Ok...I am a complete Linux Newbie. I am using Linux Red Hat 2.6.9-42.ELsmp

We have Nimbus setup to help monitor our servers and I am getting an error that free disk space on / is at 0%. Not sure how I can see what to delete. I tried running du -ks /* | sort -nr | head (found this in another post) and these are the results.

[root@IMPENTBEA /]# du -ks /* | sort -nr | head
15893484 /bea
6085780 /database
3426972 /data
1428800 /usr
955458 /proc
812248 /enterprise
248172 /root
103148 /opt
91940 /lib
29044 /var


But not sure how to see what files or directories point to the / partition. Please help!!!

du shows your disk usage, you will need df to show which filesystems are mounted separately

[root@IMPENTBEA /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
6.0G 5.6G 18M 100% /
/dev/mapper/VolGroup00-LogVol01
39G 16G 22G 42% /bea
/dev/sda2 122M 13M 103M 11% /boot
none 8.0G 0 8.0G 0% /dev/shm
/dev/mapper/VolGroup00-LogVol02
1008M 36M 922M 4% /home
/dev/mapper/VolGroup00-LogVol03
1.5G 135M 1.3G 10% /opt
/dev/mapper/VolGroup00-LogVol04
4.0G 68M 3.7G 2% /var
/dev/sda10 21G 5.9G 14G 31% /database

as a guess, I would say /data is the culprit here

and /database

My Server is Unix and it is frequently restarted and stop in starup mode what to do

Thank you for all the help guys. I am looking into this more. In /data I found a /jackrabbit directory and have been told this is esential for our application to run. I am still investigating /database.

Thank you again for all of the help.

possability here that your database logs everyting you do and the log files have filled all the space rather than overwriting the oldest entries

@Percash:

Do not hijack a thr. Start a new one, with much more detail eg Linux name (distro) and version. Give exact details of problems and relevant log msgs.

The above drive seems to be the only one at capacity.
This partition contains the root directory "/" and probable contains the /tmp folder.

many applications use the temp folder and will not start if it is not writable or full. try deleting every thing in this folder as root.

that should free up enough room to boot the system.
I noticed that your using LVM you should be able to shrink your barely used /home or other partition and reallocate the free space to VolGroup00-LogVol00. That would permanently increase the space available on "/".

I just noticed your /data folder is on the same drive as /. I would try increasing the space on this logical volume. If /data is still growing you need the space.

Thanks XWEB. I will try and see if that helps!!!!

Any suggestions for how to do this? Sorry, but am a complete Newbie to Linux. Thanks!!!

Database seems to be on it's own partition, so it wouldn't be affecting /
