Manuj,

>du -sk /var
1002440 /var

There may be some open files on /var , check with lsof to find the culprit.

# lsof /var
And sort on the filed "Size"

If you dont have lsof installed , you can download , install and check:

Cheers,
Raj.

it gave me long list, with different sizes.
should i kill the process which is eating the size?

[Kanagaraj]

Don't kill the service,just check the file using by the aby services,it may be log files.try to rename and compress it.

Don't forget to create the empty log file.

[Kapil Jha]

from lsof output see which process has open the biggest file.
and kill that process may be trim the file and restart the service.

Manuj,

>it gave me long list, with different sizes.

- You can check :
# lsof > lsof.txt
# cat lsof.txt | sort -rnk 7 | head -n 20

The above will give top 20 proceses having large open file. If you kill or bounce that process , it will release the space. You can check what process it is , by checking the pid in 2nd column. or ps -ef | grep .

Hth,
Raj.

Did someone delete a file that a process still had open?? That would show up as allocated space in bdf/df but wouldn't in du

lsof +aL 1 /var

will tell you...
