I'm actually running PiMox on an RPi4, and I'm seeing increased disk usage for no obvious reason. It seems the .qcow file keeps consuming more and more disk space. I see no reason why. 384GB are allocated for it, but everyday it consumes another GB or so. What have I missed?
Thanks.

No snapshots, but how do I enable Trim/Discard? I can't find it.
Thanks for the reply.
You check the "discard" checkbox for the virtual disk in the PVE webUI and choose a protocol that supports TRIM like "virtio SCSI" and then it totally depends on your guestOS how to tell the OS to actually send TRIM commands. For linux you for example let cron/systemd run a daily fstrim -a or you edit your fstab and add a "discard" to the mount options of the ext4/xfs filesystems.
