Re: FileSystem /var It is 97% used

Hi:

There are any number of threads in this forum dealing with nearly full filesystems.

For '/var' you could begin by running:

# cleanup -c 1

...which will remove the rollback images of patches that have been committed at least once. If this hasn't been done recently, you will likely find a great deal of space will be returned.

Regards!

Re: FileSystem /var It is 97% used

After you run cleanup, begin examining /var more closely by running "du -sk /var/* |sort -n". That will show you the largest sub-directories in ascending order so you can focus your attention on the worst offendors.

You will want to stay away from the software distributor database directories: /var/adm, /var/patches, /var/spool/sw. Manually removing entries from those can ruin your system.

You can use the du command to examine sub-directories further down the line, too. Just change the directory name from /var/* to /var/whatever/* and run it again.

Re: FileSystem /var It is 97% used

Hi,

do you have separate mount point for /var/adm/crash?

could you please check if there is any dump already?

could you please paste the output of bdf?

Re: FileSystem /var It is 97% used

Hi,

Check any core file in /var , if found core file , remove core file .u can also check that issue by rebooting server .
Also check by deleting unnecessary file.

Re: FileSystem /var It is 97% used

Daniel,

See the largest files on var:

First check these known files which grows significantly over the course of time :

/var/adm/syslog/syslog.log
/var/adm/syslog/mail.log
/var/opt/resmon/log/*


- Also to check top 30 largest files on /var filesystem:
# cd /var
# find . -type f -xdev -exec ls -l {} \; > /tmp/var_files.txt
# cat var_files.txt | sort +4 -5nr | head -n 30


- Also if you are seeing sudden growth of 95 % from a less used /var filesystem, you may suspect something wrong happened suddenly. suppose your /var FS was 50% and suddenly it is 95% , you may try looking for the files created or modified recently in 1 day or 12 hours.


- If there is nothing to trim/cleanup , you can go ahead and extend the filesystem, depending on the free space on vg00.
# Free Space can be check with:
# vgdisplay vg00 | grep "Free PE"

- also check if you have online JFS:
# swlist -l product | grep OnlineJFS



Hth,
Raj.

Yes, in the directory /var/opt/OV/tmp exist core

I can delet "core"

Yes, it is almost a year old.
You could also move it elsewhere or you could try to get a stack trace with gdb.

Re: FileSystem /var It is 97% used

James, with the command "cleanup -c 1"

there may be problems running the command?

Re: FileSystem /var It is 97% used

Hi (again) Eli:

> James, with the command "cleanup -c 1"

No, this is a standard Software Distributor (SD) tool. This is the only safe way to reclaim space from '/var/adm/sw'.

You can backup '/var/adm/sw' beforehand if you like. *Never* remove anything from the IPD (Installed Product Database) as held in '/var/adm/sw'. To do so may leave your system un-patchable. Use the standard SD tools, like 'cleanup' instead.

Regards!

How about checking /var/.audit (slash var DOT audit). This can grow very large when auditing is enabled.

Have you run cleanup(1m) yet? Most of these are patch save areas.

You might be able to remove all but the latest of:
/var/opt/hpsmdb/pgsql/pg_xlog/*

Hi (again):

> what is the best option?

2 - delete these files

Why don't you run 'cleanup' as I have suggested and *see* how much space is returned!

As for "delete these files", I presume you mean '/var/opt/hpsmdb/pgsql/pg_xlog/*' as Dennis mentioned.

Do what you like or do both! You have a very nearly full filesystem that isn't going to improve unless you *do something*.
