Disk full but no files..

Arno Haverlach — Mon, 23 Jan 2006 06:18:46 GMT

Hello,

We have got a HP-UX 11.11 system that has some problems on a partition. /oracle/admin/zipprod1 is full according to bdf but there are just a few megs used..

# bdf

Any idea's on this one..?
also is it possible to do a fsck on a live filesystem as i'm unable to umount the partition right now..

Thanks..

Hello,

Try running "fsck" to find out any inconsistency in your filesystem.

Hi Arno,

probebly a file is removed which is still being used.
do an fuser /oracle/admin/zipprod1
to see which process uses the filesystem and restart that process.

Shalom,

If a file has been deleted but the process still has a lock on it, the space will not be available.

fuser -cu /filesystem
# to display the processes.

You may kill them individually or:

fuser -cuk /filesystem
# very dangerous can halt a system if run incorrectly.

Hi Arno

did you try
# lsof +L1 /oracle/admin/zipprod1 | grep REG

This gives you the "unlinked" files.

Try to umount and mount back the file system

See if that helps.

My first gess is alsow a file that was removd when it was in used.

If this the above solutions does not resolve the probelem it can be that if there is a other filesystem mounted under this filesystems that you have files in the mountpoint you can find this "hidden"files whit:
ff /dev/vgprod1/lvol4
where you can see all the files that are on the lvol.
