Re: root file system at 99%
Hi Torsten!
:) I am not hiding anything , but if you want more information I can provide it to you, I was just trying to abbreviate, sorry I was wrong.
The "/" file system used to be 69% at all time, so I come back from leave today and I found that someone has messed up with the system

SolutionOK, but it was confusing ...
You need to look for large files in lvol3, not in other lvols (e.g. using "du").
If there is a single large files, it is likely much smaller than 1GB, because your / is 1GB only.
So a file in question is about 300MB ?
Hope this helps!
Regards
Torsten.

Re: root file system at 99%
>I meant that I could not see anything that was big enough, because normally that is under 50% figure.
And I answered that question. You may have removed an open file so it is now invisible. You need to download and run lsof to find it.
And what does this show: du -kxs /
>Try to find files with big sizes: find / -size +1000000000c -exec ls -l {} +
>The files are in /var, /tmp and other file systems, not in the root:
You need to add -xdev so it only looks at /.
>but you obviously have /opt directly in /.
Yes, I also mistakenly trusted in the bdf output. ;-)

Re: root file system at 99%
Rather than looking for big files in "/" you should be looking for big directories. A directory can be large because it has one giant sized file, or it could be big because it has 50,000 junk files in it, none of which are very big. USe du to provide a useful listing:
du -kx / | sort -rn | head -20
The two largest directories are /sbin and /etc. Anything else at the top of the list is a mistake. A common mistake is /dev -- it will always be less than 100k or so. If it is megabytes, you have a bad file in it. There are *NO* ordinary files in /dev:
find /dev -type f -exec ls -l {} \*
The above should produce nothing. Remove (or move if it is a useful file) the ordinary files in /dev.

Re: root file system at 99%
I found the problem, indeed there were some 300Mb in excess in a directory under /data/ICTPRD. Thank you very much

Re: root file system at 99%
So it was outside of these mount points?
dev/vg03/lvol1 29360128 6900586 21056081 25% /data/ICTPRD/ict_archive
/dev/vg02/lvol1 56623104 534693 52582957 1% /data/ICTPRD/dwf
/dev/vg04/lvol1 6291456 366294 5554890 6% /data/ICTPRD/bulkload
/dev/vg17/lvol1 115343360 55718343 55900917 50% /data/ICTPRD/bmd1
Ok, then it was in /.
Hope this helps!
Regards
Torsten.

So that this was valid and not a good idea:
#du -kxs /data
851336 /data
