container shows wrong disk usage?

Ok I now did

  pct mount $vmid

and

fstrim /var/lib/lxc/$vmid/rootfs

for every single vm and i got my disk space back



is there any way to do this automatically? did this happen because the containers are unprivileged?

edit: ok no the container which freed like 50GB is privileged

so maybe your thin-pool was partially corrupted and the mount/unmount has triggered some ext cleanup code? this is the only thing which comes to mind for this behaviour

I think I'll just use esxi and get away from containers
