/dev/mapper/centos-root is 100% full

[Gerlis]

My /dev/mapper/centos-root is mapped to / and is 100% full. This is causing issues with services crashing and the server becoming unstable. However, I am not sure why this keeps happening. /home is far from full, where all user data is stored. I clear out /tmp with tmpwatch, I removed old logs in /var/log and any unnecessary files.

df -h

41G backup
3.1G var
5.5G usr

The calculation is correct.

When installing the server, 50 gb of space is reserved for the main directory and backup and other system directories have consumed this space.

You can move backups into /home directory.

How can I move or back up to the home directory?

can be done in whm settings?

 

[vacancy]

mkdir /home/backup
rsync -avp /backup/ /home/backup

Check that the backups have been moved to the /home/backup folder, then delete the backup folder in the main directory.

For new backups change the backup file path from "Backup configuration > Default Backup Directory" /backup to change /home/backup

Keep in mind if you move the backups to /home you will encounter issues with quotas if you use them.

A better solution to this would he to put backups on a separate mount rather than have them included in / or /home
