File System Full /var

Harsha — Mon, 12 Dec 2005 05:41:29 GMT

Hi,
We've a machine where in it shows 100% file system usage for /var file system thro' bdf command, but actually if you go in to the /var directory and do a du -sk of each files and folders, doesn't appears to be using all the space allocated to /var file system.
Ex: /var is a 2GB file system.
du -sk under /var shows the disk space utilized to be around 600MB and odd. So what could be the problem here and where is the remaining space allocated to /var getting utilized?

Thanks in Advance for your Answers.

You can cleanup the follwing directories

/var/tmp
/var/adm/crash

Look for core files in /var

find /var -name core* -print
Cleanup also this files

hallo Harscha
when files that are in use are deleted , the space it occupied still remaines "in use".
did you remove (log)files under /var ?

if yes , thy to find out which processes were connected to the files. stop and restart these processes and space will have been free-ed.

Via SAM you can trim log files:

/var/adm/btmp
/var/adm/sulog
/var/adm/wtmp
/var/adm/cron/log (and OLDlog)
/var/adm/lp/log
/var/adm/syslog/maillog
/var/adm/syslog/syslog.log

or if you're feeling brave you could null them on the command line (I prefer to trim because you still have the most recent messages available to refer to). Do NOT delete any of these files.

You've already been given a good answer regarding the discrepancy between bdf and du so I won't repeat it.

Please check any print queue penind, or core dump files. And remove them.

Harsha,

I think you have a rouge process running on /var.

1. check the df -i and see you have free inodes, which you will have many.

2. do fuser -cu /var and know the process. Just kill those.

3. Sometimes it may require to shutdown and start the application that uses var (which you get it from fuser)
on killing / stopping and starting the application you will find it fine.

Dear Harsha,

It may be being used as the temporary space by any of the running process.

Hope this helps !

With Regards,

Siva.

Hi
First of all, you need to assign point to everyone who takes time help you:
http://forums1.itrc.hp.com/service/forums/publicProfile.do?userId=CA614859&forumId=1

In order to cleanup the /var filesystem, as above ideas, you can remove content of /var/preserve/
#rm -f /var/preserve/*

This directory contain all of vi editor recover files.

You can check out for all large files in /var:
find /var -xdev -type f -size +1000 -exec ll {} \;

If can not remove any large file, you need to extend /var filesystem!

Goodluck!

Hi,
I did a work around to sort out the disk space issue. I'd moved the /var/adm/sw/save directory to a filesystem where I'd enough space and linked to the new location. I didn't found any core files not any log files of huge size to remove or trim.After I'd requested for a restart as the machine was residing in a remote place and it's a pre-production server. Finally the system is up and running fine without any problems.

Thanks Again for your precious time in answering to my question.
