my / is 100% full but no recent large files or directories written

it looks like some user process holding the space
how to find out who/what it is?

cd /
du -k | sort -rn | more

You may wish to boot into single user mode, which makes it easier to id files when all the filesystems are not mounted.

If you have lsof try the following to see if any processes are holding open files that have been deleted:

# lsof +aL1 /

In case you don't have lsof get it from...

Hello Gregory,

Try : find / -size +10000 -xdev -exec ll {} \;

+10000 : nb of blocks with 512 bytes per block.

It will list all the biggest file of /

Hope this helps

You may have large files hidden behind
mount points. Do you have any NFS mounts?
If so, try unmounting and listing files
under the mount point.

I generally set the access on mount points
to 000. This severely limits the ability
to create files hidden by mount points.

You may need to shutdown the auto mounter
to free up some mount points.

Also check for files which arent really needed under /. Example for core file, or some output log files etc.. worth getting rid of these. Also Check for any directories owned by owner other than root, which are not suppose to be under /..
Also if package is moved to failover node and users still dumping files under mount point directories..
Several possibilities..

Hope it helps

If you tape drive was not connected well, and backup could fill your /dev with the backup data, that could make your / 100% full.
