Look for unlinked but open files, it may not be Ceph at fault. Suboptimal logrotate rules can cause this. lsof, fsck -n, etc.

Hi Matthew,
Cephadm doesn't cleanup old container images, at least with Quincy. After a upgrade we run the following commands: sudo podman system prune -a -f sudo podman volume prune -f
But if someone has a better advice, please tell us.
Kind regards, Sake

Hi All,
*Something* is chewing up a lot of space on our `\var` partition to the point where we're getting warnings about the Ceph monitor running out of space (ie > 70% full).
I've been looking, but I can't find anything significant (ie log files aren't too big, etc) BUT there seem to be a hell of a lot (15) of sub-directories (with GUIDs for names) under the `/var/lib/containers/storage/overlay/` folder, all ending with `merged` - ie `/var/lib/containers/storage/overlay/{{GUID}}/`merged`.
Is this normal, or is something going wrong somewhere, or am I looking in the wrong place?
Also, if this is the issue, can I delete these folders?
Sorry for asking such a noob Q, but the Cephadm/Podman stuff is extremely new to me :-)
Thanks in advance
Cheers
