Subject: SUMMARY: Unable to Create New Boot Environment
Message-ID: <e31f9ea51003082029g5b34c0e1pca658ef2136ecfdf@mail.gmail.com>

The problem ultimately turned out to be a 'corruption' issue it seems.

Turning on the the debugging option in /etc/default/lu ( which I did not
know how to do but I will REMEMBER it) led right to the problem ( creation
of inode failed) I did a newfs on the underlying slice and rebuilt the
metadevice and the problem cleared up.

Thanks to Anthony, Darren and Espen for their answers and suggestions all
were valuable.

As several folks realized and pointed out, yes I had two questions with
find in the same script.  I separated them into two posts so that they
could have separate summaries.

I asked

The answer

Find *does* honor regex, I just wasn't looking at it right.  You cannot
negate the parameter to an expression, you negate the expression itself.
So it isn't
-user !root
it is
! -user root

the code snippet is
###
### Should files owned by certain users be excluded from the list?
### Uncomment exactly one of the ADD definitions below.
### No users to exclude?  Uncomment this line.
### ADD=""
###
### Exclude any files owned by root? Uncomment this line.
### ADD=" ! -user root"
###
### Exclude any files owned by root or epicadm? Uncomment this line.
ADD="! -user root -a ! -user epicadm"
###
[...]
/usr/bin/find ${SOURCEDIR} ${ADD} -type f -mtime +${MAXAGE} -print

other suggestions I received:
* use -not -user instead.  That generated a syntax error.
* escape the !  (ie, \!).  That works on the command line, but within a
script
  you are escaping an escape, so it no longer behaves nicely.
* do an ls grepping out the user before feeding it to find.
* many many suggestions to get the negation to the -user expression, not the
  parameter to the expression (the username), which was the bulk of my
problem.
* use gnu find to get regex.  No, I did not have to go with gnu find, I just
  needed to get the regex syntax correct.  <grin>
* make sure you ask find to the regex, not the shell.  The shell just does
  plain simple globbing.
* use the -prune directive (-user root -prune)  No, that is not what -prune
  is for.
* explicitly list all of the users for which it is ok to delete their files.
  hmmm.  maybe not.
* use perl.  I'd rather not kill a mosquito with a bazooka.

This list is wonderful.  Thanks to the 28 individuals (and counting) who
gave me suggestions.

Solution

no, its not a bug.  I'm trying to do too much at once.  Do it in two passes.
First, using -type f, remove elderly files.  Then do a second pass to remove
directories that are empty.

The code snippet

/usr/bin/find ${SOURCEDIR} ${ADD} -type f -mtime +${MAXAGE} -exec rm {} \;
###
### now go through ${SOURCEDIR} and look for directories over the specified
### age and are empty.  They can be deleted.  An rmdir will fail if there is
### anything in the directory.  STDERR is directed to /dev/null to suppress
### the expected errors when a directory is not empty.

/usr/bin/find ${SOURCEDIR} ${ADD} -type d -mtime +${MAXAGE} -exec rmdir {}
2>/dev/null \;

almost all of the suggestions centered around using -type and making two
passes.

Thanks to the 20-odd and counting folks who pointed out the wonders of the
-type flag and two passes...

Message-ID: <693CD04A19309243A42029FB8079E3F5169CF03F18@WSMSG3104V.srv.dir.telstra.com>

Thanks to everyone who replied to my question.
Neil Martin and Rob De Langhe solved the problem for me.

Neil suggested this wiki:
http://wikis.sun.com/display/StorageDev/Symmetric+Multipath+Support+for+Solar
is

and Rob said:
    likely the typical error in the "/kernel/drv/scsi_vhci.conf" file...
    To enable on Solaris-10 :


    edit the file "/kernel/drv/fp.conf" and sure the following entry is set :
    mpxio-disable=no

    edit the file "/kernel/drv/scsi_vhci.conf" and make sure the following
entries are set :
    load-balance="round-robin";
    auto-failback="enable";
    device-type-scsi-options-list =
    "EMC     SYMMETRIX", "symmetric-option";
    symmetric-option = 0x1000000;
    Make sure you put exactly the correct number of space between "EMC" and
"SYMMETRIX", or it does not recognize the disks as to be considered by MPxIO

So it appears that just running the stmsboot command is not enough.  It's
necessary to manually add the third party device id in the
/kernel/drv/scsi_vhci.conf file.

The original question:
I'm trying to configure multipathing on some SAN storage but it appears that
it's not being recognised as a dual path system.
Devices 5, 6 & 7 below are dual pathed with devices 9, 10 & 11, each about
67G.
System is Solaris 10 10/08 (update 6).
I was expecting to see the 6 devices appear as 3.

        I run:
          # stmsboot -D fp -e
        then reboot

          # stmsboot -L
        stmsboot: MPxIO is not enabled

        Can anyone suggest why stmsboot is not configuring the multipathing?

Thanks to the couple of folks who replied.
The jbod array is semi-intelligent and likes to assign it's own scsi ids 
to certain slots. This isn't working correctly.
I rebooted the jbod.
I now have my new ultra-320 drive with an id of 15 where it should have an 
id of three.  I can label the disk but can seem to get disksuite to write 
to it.
I'm going to chalk this up to an incompatible replacement drive and move 
on to plan b... rooting around in my spares and finding a good used drive 
as a replacement.

SUMMARY,  ..  Help for "+lost system +control +key sunfire netra +v440 -PGP"
Looks like a lost key or keys may not be a big problem

Do you mean these keys:
http://shop.ebay.com/?_from=R40&_trksid=p3907.m38.l1313&_nkw=v440+key&_sacat=See-All-Categories
I've a couple v440's, both use the same key.
You might also search google products for "v440 key", sort price lowest to 
highest, i think it's also p/n 240-4341 but doublecheck with a vendor:
http://sunsolve.sun.com/handbook_pub/validateUser.do?target=Systems/SunFireV440/components&source
Just noticed Sun has a 'buy' link there too, $30.

------Original Message-----
I can probably dig up a key for you.
Scott

-----Original Message-----
If I remember there are two keys one larger one where the handle is triangle shaped and one smaller one.
The larger key controls system power up for the front panel I believe the smaller key controls disk access.
I have the larger key, and maybe the smaller one, it might be for an e240, that I kept as a memento that I could send you if you can't find a replacement.
Jordan

-----Original Message-----
don't know about the V440, but with my E250's that is certainly the case. I have a store room with several surplussed E250's that I harvest for spare parts/bodies when emergencies come up. Many of them arrived without keys or drives. Any one key will fit any E250.

-----Original Message-----
I Google'd "sun v440 key" and found reference to part#
	240-4341
and further searches suggest that it may also be part#
	240-4429
Allan

-----Original Message-----
I've got a handful of V440's we're getting rid of. I think the netra version is about the same hardware wise as the standard model. As I recall the same key is used for everything. I probably have a few keys sitting around somewhere, assuming I can find them I could drop you one or two in the mail. I'm out of the office today but could look around on Monday and see about digging them up if you want. All of mine use the same key, ...

Subject: Summary: Can a user-process cause Solaris to boot-up, with

Message-ID: <c4ab18df1003160559w1c533e2ah34232adba22d4ee0@mail.gmail.com>

Thanks a lot to all,

Most responses agreed this can be power failure, or much more likely
Oracle RAC evicting the node and forcing it to shutdown "improperly"
to avoid having it "save anything"...

We confirmed from Oracle RAC log files on other nodes that the host
"elli" was indeed evicted, and also found a bug report mentioning
that:

6389053 Oracle RAC defines "uadmin 1 1" as reboot command, trips over
boot archive check after reset

So that would explain the observed system logs.

Thank you all very much.
Mohamed.

Hi, all.

Thanks to everybody who responded.

1. I had two people point me to the correct documentation at the Sun web site:
http://dlc.sun.com/pdf/817-4048-13/817-4048-13.pdf. Thanks! My other info was
not sufficient for sure.

2. Per the instructions, you have to be careful about which thermal material
is (a) currently on the existing CPU/heatsink and (b) what is provided with
older vs. newer 440 systems. The documentation is clear about how to proceed
... depending on whether you have the thermal paste or the glue pad. However,
the procedure involves having the processor freshly turned off (i.e, still
hot) in one situation - see the doc - so some experimentation is needed if you
do not know the answer.

3. My new heatsink came with a thermal glue pad, so I planned to use it as a
replacement after cleaning the old material off.

4. From the ten or eleven responses, only one person said that the "replace
the fan" idea would work, since he had recently done this about 4 months ago.
I took that as a good omen later - see next few lines. :)

5. I went looking for isopropyl alcohol around here to clean the surface of
the cpu, but could not find any handy, so I took the risk of removing the old
fan and installing a new one - *without* removing the existing heatsink at
all.

6. The fan is held in place with two screws (not four as I had incorrectly
mentioned earlier), and is fairly easy to remove. Just have to be careful to
move the fan wires out from under the two metal guides on the heat-sink
without moving it around. And you may have to remove some of the memory cards
that are in the way to reach the fan screws.

7. You have to be careful with the small Phillips screwdriver, and you have to
be careful not to drop the screws - our system is rack-mounted, so finding a
dropped screw could have been painful. Fortunately, my dropped screw landed on
top of the small green heatsink next to the fan, so it was an easy retrieval.
Whew!

In any case, the system powered up fine, both CPU fans are now working and the
system is back in operation.

Thanks again, everybody!

Subject: Question about replacing CPU fan (or CPU heatsink) on a V240.

Hi, all.

CONTEXT:

We received a CPU fan error message on one of our V240 systems. I powered down
and pulled the cover and sure enough, one of the fans (there are two tiny ones
on the CPU heatsink) is sticking and not spinning too well when I move it by
hand or an air can. The other one does fine.

I ordered a replacement, and instead of just a fan, I received an entire
heatsink with two fans, etc. More expensive, but ... okay! FWIW, it appears
that removing and changing the fan may be more pain than needed - there are
four tiny screws that could get stripped, torqued down too tightly to spin, or
come loose, etc.

So, I decided to proceed with changing the heatsink instead. (Although I am
still open to just changing the fan if people feel that is the better
approach).

QUESTIONS:

My experience with changing heatsinks (on Intel windows systems for example)
required cleaning the heatsink and cpu surface carefully, using thermal paste
(Arctic Silver 7 for example) between the heatsink and the processor, etc.,
etc., etc.

Physically changing the entire heatsink appears to be very simple on the V240
from what I can see, *BUT* the instructions I have found do not state anything
about using thermal paste, etc.

	What are the Sun requirements here?
	Will I mess things up by using thermal paste?
	Do they require thermal material?
	Would it be better if I did so?
	Or would be better to simply remove the old heatsink and install the new one
(without any paste, etc.)?
	(Or should I simply attempt to unscrew the fan from the old heatsink and
replace it with a new one from this new heatsink)?

Thanks in advance, and I will summarize.

Hi All,

I would like to thank all who answered and explain that sched is just
waiting for the disk and should not be blame on. Especial thanks to Gary
Paveza who payed my attention on high fpi which means an active reading from
the file system.

iosnoop from DtraceToolkit showed me a process which was reading a lot small
files. Files were moved to CFS and the problem has been solved.

Thanks again and best regards,

Thanks for the response from Bismark Espinoza, Darren Dunham, Darren
Brechman-Toussaint. 
There is no quicker way to dump quota information directly in order to find
out files owned by particular user.  ncheck and quota are the approach,
although it is time consuming if you have a big filesystem.
For nfs, showmount can map the shared directory to remote nfs client. With the
aid of find, I can find out how many filles were not accessed in the last one
year.  Therefore, I can do the cleanup work.
Darren Dunham also suggest using nfslog, which can outline nfs daemon
activities. 
Thanks for all your help,
Zhu

Hello All,


I have one solaris 9 NFS server with multi Terabyte nfs sharing. The
filesystem is Veritas vxfs 4.1 with quota enabled.


I need to find out where are  the file/directory for particular user.
Using
find or ncheck is not efficient on such big filesystem. It took a
hour to
finish one run.:-) My understanding of quota filesystem is it
maintains an
internal structure to track inode usage information for
every user. Is it
possible I can access that information directly? I
assume that could be very
quick. 


Second question is whether it is possible to find out which nfs sharing is
being used by which client?


I have scratched my head for a hour. Could anyone share their thoughts? I
will summarize.


Thanks in advance,


zhu

A few replies.

Stuart Saxon mentioned Service'ability Reliability Acces'ability  
Support'ability (SRAS) and "Traffic Light Patching" (TLP). TLP however  
was EOSL in December 2007 from what I can tell:

	http://blogs.sun.com/patch/entry/patch_automation_tools

Damir Delija brought up SANS' "User Vetted Tools" (see Critical  
Control 10), and some do mention Solaris support on their web page:

	http://www.sans.org/critical-security-controls/user-tools.php

Rob De Langhe mentioned that the Explorer tools collect patch  
information, but that's not much different than PCA.

Karl Vogel said that I should probably just go with PCA plus some home- 
grown scripting.


So it seems that there's no consensus on this.

Subject: SUMMARY: ZFS in Production
Message-ID: <ce3ed3611003230616j40552bb2g6f1820e6e346cb76@mail.gmail.com>

Sorry for the delay with this summary. I was surprised that production
use of zfs pretty common. Unfortunately my client was not willing to
switch from his tried and true ufs.

The common thread in the responses was that zfs is particularly well
suited as storage for file services. Less well suited for databases
but still very good provided tuning best practices were followed.

One responder pointed out that you can't take a lun back from zfs as
you can with a veritas disk group for example.

All the responses I received follow...

#############################################################################
I wrote a perl script to take hourly snapshots and to remove old
ones.  The idea for it came from the Apple's TimeMachine concept.
The thinking behind is that the users should be able to go back to a
snapshot several months old and copy back a file they deleted.
However, unlike the Apple TimeMachine, this script does NOT make
snapshots in a second drive.  So, if the drive dies, original data
and the snapshots all go with it.  I'll work on the next iteration
of the script to move the snapshots to a second drive/array.

###########################################################################

I've been using it for the past year, plus some.

I've been using the compression feature to conserve disk space.

I usually create one large pool, and create all the filesystems under
it. (All of the free space is share by the pool, and not locked away in
separate filesystems.)

I've been using the snapshot feature to do point in time backups. It
greatly simplified the scripts I had written to do UFS snapshots with
'fssnap'.


#######################################################################

We've been using zfs for years.  You don't describe your application,
depending on the particulars, you may want to look into tuning:
http://www.solarisinternals.com/wiki/index.php/ZFS_Evil_Tuning_Guide
We make some modifications for Oracle with SAN disk, but for most uses
don't change anything.

As far as non-evil tuning, depending on your app you may benefit from
compression and other settings.  Even parts of Oracle benefits from
compression - we found that RMAN backups happen faster and save space
when sent to zfs with compression enabled.  Test out settings on your
app.

Also be sure to read and understand the Best Practices guide:
http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide

We use snapshots for many different situations.  On some servers we
snap partitions on a daily basis and keep these for 2-7 days,
providing us with instant recover capabilities.  To do this be sure to
understand how space is consumed with snapshots.

We also snap before upgrades to provide rollback and comparison in
case something doesn't work as expected.

In some cases we snap for transmission to remote site, using zfs
send/receive capabilities.  Still not automated or regular, though.

We're also investigating using snapshots for backup, e.g. snap
partitions and backup the snaps instead of the actual partitions.


When using snaps be sure to understand how they consume space, how
your application reacts to the snap (e.g. does database need to be
down for consistency) and be sure to clean up after yourself.  We've
had some admins create a snap, forget about it for a year, and then it
causes problems consuming too much unused space.


Good luck,

-f
http://www.blackant.net/

###################################################################################

The attached text file is the perl script.  It has a "requre" line
which I commented out.  That's a localism to get some variables
pre-loaded for our machines.  If you find some variables (ie:
$HOSTNAME) missing stuff you can figure out pretty early on.

This particular script is being used for a RAID array that has large
datasets.  The lab tells me that the original data can be re-created
so they don't want to back it up.  This is a way to guard against
accidental file deletions.  This is NOT a backup strategy.  HW = Sun
Blade 2000 + Anacapa RAID arrays.  Production and Dev.

We use ZFS for SAN luns to aggregate them to a large filesystem and
to lay OpenAFS on top.  (See www.openafs.org to see an enterprise-class
multi-platform filesystem)  We also use ZFS to make filesystems out of
Sun J4400 JBOD arrays.  We have ~5-7 TB of production data that uses
ZFS at the moment.  All production.  Does not use this script to make
backup snaps as OpenAFS has its own backup snapshots.

We run Solaris on Sun SPARC hardware, not x86, if that makes a
difference.


#####################################################################################

Awesome. Bloody easy and lots of value/features above/beyond ufs.

I've not moved to zfs boot environment. But, everything else on my
newer Solaris 10 systems is ZFS. I love it. I'm using it on a
StorageTek 2510 iSCSI device and on a J4200 multi-homed SAS device.
Also on the extra internal drives (beyond the hardware mirrored boot
drive).

You'll find recipes online for rotating snapshots. They take virtually
no resources unless/until they are needed for data replication. I
implemented a basically endless version of that that allows me to
recover data files from any day in the semester for our bio-imaging
class/laboratory.

   #!/bin/ksh

   # this should be run off cron before midnight every night.
   # it will generate a date stamped snapshot of those zfs filesystems
we deem important.
   # `date +%Y%m%d%H%M` generates a date stamp for the snapshot name
of the form 200909151431,
   # which corresponds to Sept. 15, 2009 at 2:31pm. These can be
viewed with `zfs list`.
   # for a quick overview of recovery, roll back, etc., see
   #       https://www.sun.com/offers/details/zfs_snapshots.xml

   /usr/sbin/zfs snapshot biopool/bioimaging@`date +%Y%m%d%H%M`;
   /usr/sbin/zfs snapshot biopool/capstone@`date +%Y%m%d%H%M`;
   /usr/sbin/zfs snapshot biopool/quantbiol@`date +%Y%m%d%H%M`;
   /usr/sbin/zfs snapshot biopool/students@`date +%Y%m%d%H%M`;
   /usr/sbin/zfs snapshot jpool/outreach@`date +%Y%m%d%H%M`;


of course, I have to clear those out manually, and/or create a script
to clear them out. However, I still haven't gotten a clear policy
statement from the faculty on what time frame they need; and, since it
still isn't eating much space compared to what I have, it all still
sits there.

The one complaint I have is that there is no replacement for
ufsdump/ufsrestore. The zfs send and receive only does full file
systems. You cannot recover just one file or directory using those
tools. So, they aren't really functional for backups. Amanda can be
configured to use them, but it turns out that gnutar is more
functional in terms of the use cases that typically turn up. That's
one reason I haven't gone to zfs boot environments. I depend on fssnap
and ufsdump/ufsrestore configured with a wrapper in Amanda to backup
my primary partitions. It could be I just don't know enough yet or
don't have enough experience to have confidence, and, perhaps, zfs
might actually be better for boot environments. Anyway, my setup works
fine for me.

Something I haven't seen a clear analysis of yet is higher level
failure modes for zfs. Ok, so I have raid 6 with a hot spare
configured using zfs raidz2. But, what if I was away on vacation,
didn't pay attention, and I got 3 drives failed. Now, suppose I had
two of those raidz2 (or even more for that matter) configured into one
zpool. Do I lose the entire zpool? Or will it self heal and at least
give me what data happened to be on the surviving raid components?
Based on the lack of an answer for this, I don't use one giant zpool
with multiple raidz components for large scale storage. That might be
easier in terms of allocating space and the usage of space, but I
don't want to risk it.

So, I use multiple zpools rather than putting all my eggs in one
basket. This is much better than the old situation of ufs where you
have a gazillion drives with even more partitions, and you have to
manage who gets what space and where directories are mounted and all
that stuff. Some of my Solaris 9 systems with over 30 individual
drives have become a bear in that respect. With zfs, I can ask a
faculty member to buy a drive and I will allocate him a certain amount
of space, but I don't have to just mount that drive and give him a
directory on it. The disadvantage is that I can't just add a drive to
a zpool and have any kind of raid protection. I have to wait until I
have enough drives to make sense and set up a raidz. Then I can set
reservations if they are appropriate. I would like a more incremental
way of adding space to a zpool or even to a raidz component. Say, I
have 3 drives in a raidz and want to expand it to 5 drives. I have to
zfs send the data to something else, destroy the raidz and remake it,
and then bring all the data back.

I found one of the people who works on zfs posted a specification of
how to do that and invited people to implement it (it's open source
after all). But, as far as I know, it hasn't been done.

Anyway, I've been using zfs for a couple of years and love it.

If you happen to have a StorageTek 2510 iSCSI device or something
comparable, I posted a very detailed summary on the sun managers list
on how to set that up with zfs. However, if you haven't got one, I
would recommend against it. The J series is just way easier to set up.
The J4200 or J4400 with SAS.

One thing I haven't done is to use the SSD drives to boost overall
speed. That hasn't been an issue for me. But, if raw speed really is
an issue, zfs can make use of an SSD for it's write intent log and end
up running much faster. As far as I know this isn't possible with any
other existing file system. It's part of what allows the Sun 7000
series storage systems to beat out NetApp in price/performance.

We use ZFS extensively in all environments including production. We
have been migrating systems from Veritas and SVM OS filesystems to ZFS
with great success. Our newly jumpstarted systems are all using zfs
root. The best advantage is the ability to create a new boot
environment using snapshots, then patch that BE live and simply reboot
into it. Turns a 3-hour downtime for patching into 10min.

We use ZFS to create application filesystems using internal drives in
a mirrored pool. I've personally used it to manage SAN LUNs, though
this is not ready for prime-time since we absolutely need multipathing
and MPXIO does not make it straightforward to test that both paths are
actually active...it'll just tell you whether mpxio is turned on or
not. We need explicit tests for when we do SAN maintenance.

I've tested ZFS fault tolerance on internal drives (either system or
for app filesystems) and it works as advertised, and it's real easy to
replace failed disks.

Hi Victor,

I've been using zfs in a production oracle environment for about a year

Hi Vic

I have implemented (an early version) of ZFS with 11 x T3 arrays with
a V480 for around 2
years now in a production server giving both NFS and Samba file
serving to a workgroup of
50 people and have approx 8Tb of data managed. So far it has held
together really well without
incident, very happy with it. Weekly backups are approx 3Tb to ZFS disk.

We snapshot every night and keep 14 days worth of snapshots available.
Also use snapshot for
tape backups. A real winner with the Windows users to beable to get
last weeks version.....

ZFS is the best thing that has come out of the OS industry in the past
years IMO.  I've used it for years now, I use ZFS to create Sun virtual
servers within each specified ZFS.  I've created scripts that send
incremental changes to off-site servers, perfect for DR scenarios.  The
list goes on.  Can save a company hundreds of thousands of dollars by
virtualizing and replicating data.  I would not hesitate to use it in a
production environment.

My biggest problem is the way that I/O to a pool with a bad disk slows
to a crawl until it's detached,
despite remaining mirrors.  SVM usually doesn't do that. I've seen ZFS
resilvers  saturate the disk subsystem
too; a way to avoid starvation has been requested from Sun for over a year

################################################################################

Just remember one thing Vic you can not take away devices you add to a
zpool currently which would
result in you recreating your zpool if one of the devices would have
to be removed.  I have used zfs in
prod environment and it all depends on what you trying to do with it.
We are using one of sun's open storage
products that has zfs built in, which was purchased to replace 3 emc
clarion's (note: not based on my
recommendation) and to say the transition has been flawless is a
understatement.  We have nothing
but problems problems problems.  I am not trying to trash sun or not
recommend zfs for what you are
doing but I am just sharing my experience.

Thanks,

Hi Victor,

ZFS is certainly production ready. I have been using it for quite a
few years now in various configurations and
for me it has been very reliable.

Primarily I am using it in bothe ZFS mirrors and RAIDZ's. Biggest
RAIDZ is a 35TB configuration on a J4500
used as a staging areas in Disk->Disk->Tape for Veritas Netbackup.
Handles arund 3-4 TB a day of new data
and dat being flushed. This is on a 10 Gige attached T5220 server.

Another great use I have is fo Squid web caches where the ARC cache
proves to be a great addition for speeding
up web queries. My caches have between 1500 and 2000 simultaneous
connections to them. Works a treat there
for 24/7 type workload.

Also using it for compliance archiving for email as well on another J4500.

If you really want to get a lot of info on who is using it, try having
a look through the zfs-discuss at opensolaris.org
archives. This question gets asked regularly with plenty of good user
cases being reported. I have certainly
done so there in much more detail than above.

Hope this helps.

/Scott.


PS. Further to m previous email.

I have foind  snapshots to be fantastic in multi stage upgrades of
varyong software. I have used
it to great affect with a Blaackboard upgrade that involved multiple
Oracle updates and schema changes.
If there was a problem at any stage we just found the cause, rolled
back, fixed it and the did the step
over until we had a succesfull outcome. at that point we snapshotted
and moved onto next step. Very,
very helpful with a 20 GB database!

##################################################################################################

On a Solaris x86 (Actually a Nevada deployment) I've used/setup ZFS
snapshots for a client to do daily snapshots of his Accounting
database that is presented as a SAMBA share to the clients.

Haven't hear any complaints etc. for the past 3 years...

#########################################################################################################

First off, ZFS is production-ready, at this point, it's not a concern
with it being out for so long now.
I am using ZFS snapshots for a group of users who need multiple copies
of the same data from production,
but yet need to modify it for each test environment, which is an ideal
use of ZFS snapshots + clones. I'm
able to provide 8+ sets of test data, and no additional blocks are
used until they change data within each
test environment. Furthermore, because its test data, I've set ZFS
compression on the filesystem to
save disk space; with some types of data ZFS compression is actually
faster because if the data is
highly compressed in memory, then there is less I/O. The whole process
is very scriptable, and the
only command used is different variations of 'zfs'.

The answer:

It cannot be done.  The user is defined by the client side before connecting
to any server.  Several people suggested UseLogin in the sshd_config file, but
that did nothing.  I've put the proper usage in the /etc/issue file so that
inbound connections will know that they need to specify

Hi all, thanks for replies from:

  Michael Horton
  John Hallman
  Crist Clark

It sounds like this is currently not really possible with ipfilter.
Based on feedback I got on the ipf mailing list, it sounds like folks
_expected_ that it work and were interested in using dtrace to figure
out why it doesn't.

However, the multihome setup I'm using is most typically done when the
interfaces are on different subnets.  The way we had things set up just
wasn't really something planned for.

Recommendations are to rework the infrastructure and use IPMP/LACP if
using both physical links is truly required.

The ipf syntax I was using is correct in theory, it just doesn't do
what I'd expect.

Thanks for all of the replies and suggestions.

I did see the xpdf package on sunfreeware.com and was unaware that "pdftotext"
was a part of it.

I thank Francisco Roque for pointing this out to me.

This is what I needed.

I'm in need of a PDF to Text Converter that runs on Solaris 8 or 9.
Does anyone know of a free source?

Update 2 that is multipathed through two brocade switches.  Each LUN is split
up into two filesystems using SVM.  This server has gone un-patched for some
time now and it currently does not have a mirrored root filesystem so it is
just going to be easier/cleaner to reload the machine rather then patch.  In
order to reload I need to move the array to a different host but I am having
trouble determining the best way to go about it.

SVM partitions were not set up using disk sets so a simple import is not going
to be possible.

I didn't realize that MXPIO names were based on the Volumed ID of the LUN that
is reported to the OS by the FLX240.  This was made obvious once I opened
SANtricity and looked at the LUN properties.  This is a no brainer now that
the names generated are predictable.  Thank you to Scott Lawson for tipping me
off.

Now I can see that it's supposed to be in slots J2900, J2901, J3001, and J3000. But according to the doc, they come in four groups, A0, A1, B0, and B1. My question is, how do convert the J2900, J2901, J3001, and J3000 to one of the four groups? The docs don't say.

Thanks.

Summary:

* General consensus is that running large Oracle DB's in zones should work
just fine.

* There is a bit of disagreement about what kind of performance impact
running a Oracle DB in a container will have. Some folks said there should
be none while others suggest there will be some. I did find this blog post
though that shows there will likely be some performance impact:

http://blogs.sun.com/JeffV/entry/virtual_overhead

 * Running Oracle RAC nodes in containers is a no go since the clusterware
software requires lower level access than the container allows.

* One suggestion to dump Sparc in favor of X64 sun boxes.

* While no-one disagreed that it is possible to move zones from machine to
machine if needed it was suggested that I look into Sun Cluster or Veritas
Cluster to do a similiar thing but in a much more automated way.

* You can use solaris zones resource controls to limit the licensing costs
of Oracle by limiting the number of cpu's a zone has access to.

* Be aware of how you are going to backup the databases in the zones. As
they are all sharing the hosts network resources you can quickly run into
throughput bottlenecks during backup windows.

* One comment that the best way to divide the cpu's out is via CPU pools and
that it doesn't really matter if you use dynamic pools or not. The
recommendation was not to use the FSS scheduler. Also recommended not to
split out the memory among the zones due to some issues with resource caps.
(I don't have all the details on this yet.)

* About mount points.

So I think that the best way is to mount vxfs file system in /etc/vfstab to
