Disk full, /usr/.tempdisk file very large

[seezee]

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

If that's full, you will need to go clean /tmp.

As noted in the original post, I've already done that.

Then it should be safe to delete it or create an empty file with the same name? It appears to be a binary.

FWIW, Cyberpanel does not appear to be installed. OLS WebAdmin is installed and running on the standard port.

/var/tmp is about 600K after the latest reboot.

/usr/.tempdisk is a whopping 1.5GB.
