root file system at 99%

Hi

 

I know that are any posts regarding this issue, but I dont seem to get it right. I have the "/" at 99% I quite dont understand why. See an output of ls -lrt:

Re: root file system at 99%

>I have the "/" at 99% I quite don't understand why.

 

What do you not understand?  If it says you are using 99%, you are.  If you can't add up the file space, you have removed a file that is still open.

 

What does this show: du -kxs /ora /data /interconnect_processed /sbin /bmdtmp /opt /dev /.mozilla /home

 

If these take a lot of space, they shouldn't be in /:

drwxrwxrwx   3 root       sys             96 Sep 29  2010 ora
drwxrwxrwx   3 root       sys             96 Sep 29  2010 data

Re: root file system at 99%

thank you for your reply, I meant that I could not see anything that was big enough, because normally that is under 50% figure.

 

But, the outputs requested by you:

#du -kxs /ora
16      /ora

 

#du -kxs /data
851336  /data

 

#du -kxs /interconnect_processed
0       /interconnect_processed

 

#du -kxs /sbin
103136  /sbin

 

#du -kxs /bmdtmp
13224   /bmdtmp

 

#du -kxs /opt
14783248        /opt

 

#du -kxs /dev
80      /dev

 

#du -kxs /home
183880  /home

 

 

 

Re: root file system at 99%

Try to find files with big sizes

ex:

 find / -size +1000000000c -exec ls -l {} \;

files>1gb

Re: root file system at 99%

The files that found with the comand "find / -size +1000000000c -exec ls -l {} \;" are all outside the root (/).

 

The files are in /var, /tmp and other file systems, not in the root:

 

find / -size +1000000000c -exec ls -l {} \; | more

Re: root file system at 99%

Did you try to find the files for ex 500mb?
May be you have audit running on the root. Check /etc/rc.config.d/auditing file. There you can find path to audit folders

I really wonder where is lvol5 and lvol6.

 

lvol6 usually is used for /opt, but you obviously has /opt directly in /.

 

Could you please post your

 

# vgdisplay -v vg00


Hope this helps!

Torsten.

Re: root file system at 99%

So you just did not post the complete "bdf" output in the beginning ... confusing!


Question is still, why /data is directly in root???

Hope this helps!
