Disk full, /usr/.tempdisk file very large


New Member
My server shows 100% full.

I've cleaned out the logs and the /tmp directory, but it wasn't enough.

One of the largest files is /usr/.tempdisk. The file is owned by root is 1.5GB in size. Is it safe to delete it? How to prevent it from growing to this size again?

Running Ubuntu 20.04.1 LTS running on Google Cloud Compute with OpenLiteSpeed.

EDIT: I found some more logs to delete but I would still like an answer to this question.

Are you running Cyberpanel? CP uses /usr/.tempdisk as a temp disk for /tmp. This is what I have under /etc/fstab:
/usr/.tempdisk /tmp ext4 loop,rw,noexec,nosuid,nodev,nofail 0 0
/tmp /var/tmp none bind 0 0

FWIW, Cyberpanel does not appear to be installed. OLS WebAdmin is installed and running on the standard port.
user@openlitespeed-wp-hiplains-vm:~$ cyberpanel listUsers
cyberpanel: command not found
/var/tmp is about 600K after the latest reboot.

/usr/.tempdisk is a whopping 1.5GB.
