  • login as root ;

  • try :

# find /* -xdev -maxdepth 0 -type d -exec du -s {} \;

this should give you a report of disk usage per directory ;

HTH

good luck, and success !

If you tried deleting files that were in use to free up space, then they still exist and won't truly be deleted until the process holding them open is killed or you reboot the system.

  • you see ... there may be directories whose name begin with "." - which will not be found by the command I suggested ;

  • try :

ls -aF /

to see if there are any such directories ...

ok ?

Can you reboot the computer? This will clear any files which have been deleted while they were still open by a process.

Also check the root directory itself visually and look for rogue large files:
ls -ald /* | more

Is that the total size of the partition? I only see 4 GB allocated for the total slice. I am just wondering what kind of server is deployed.

/ is 4G only
/var 8G
/opt 8G
/boot 200M

Reboot done many time but still issue is there

see for any oracle related application which uses system disk space and does not release it.
Once you kill or restart the process , then ur disk space issue will go off.

server rebooted many time, No oracle installed on this server
