What Is Eating CentOS Disk Space

right ?
I just noticed from you df -h above, /home is already a separate logical volume. That is not the problem. The issue is that your /var is too big. Run this instead...
du -smx /var/ 2> /dev/null | sort -n | tail -n 5*

Hi Sam,
I had mounted a 2 TB hdd on my server, when i had this issue ...
@ arround 10 Am IST server got stuck. And i started building new one ...................Removed the HDD and mounted to the new one. -
As soon as i un mounded the External hdd ., i tried df -h
and got the output..........root@trvbackup [~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_trvbackup-lv_root
50G 28G 19G 60% /
tmpfs 3.9G 0 3.9G 0% /dev/shm
/dev/sda1 485M 53M 407M 12% /boot
/dev/mapper/vg_trvbackup-lv_home
402G 145G 236G 39% /home
/usr/tmpDSK 1.6G 38M 1.5G 3% /tmpThat means 19 gb free as soon as i unmounted my External Hdd.
-
And please find the output of this without The external Hdd
root@trvbackup [~]# du -smx /var/* 2> /dev/null | sort -n | tail -n 5
4 /var/tmp
30 /var/cache
377 /var/cpanel
5323 /var/log

That would be coincidental. Possibly a process was running and holding open files. Removing the drive might have killed the process releasing the storage for the filesystem to clean up.

root@trvbackup [~]#Yes, that supports my theory. It appears to have cleaned up by the time that you ran this the first time.

So Is there any way to figure it out , so that i can take necessary steps for the next time..

Most important thing is to have monitoring watching disk space on a regular basis so that you can see if it starts to fill up and get an alert. Every business has this issue. Logging or any number of things can cause it to fill up so having a way to keep tabs on it is always important.
-
Sure , will keep monitoring it regularly.
Thank you very much for your help and support SAM........... -
@ajin.c you bet. We are here to help
