Can you show ls -lh /srv and ls -lh /var/snap/lxd/common/lxd/storage-pools/ ?

23

[root@centoslxc ~]# ls -lh /srv
total 0
drwxr-xr-x. 2 root root 6 Oct 19 23:14 lxc
drwxr-xr-x. 9 root root 162 Oct 13 15:11 lxd

24

Can you show ls -lh /var/snap/lxd/common/lxd/ too?

Ok, not seeing anything obviously wrong at that point.
Try:

  • umount -l /run/snapd/ns/lxd.mnt
  • rm /run/snapd/ns/lxd.mnt
  • systemctl start snap.lxd.daemon
  • journalctl -u snap.lxd.daemon -n 30

You are a life saviour thank you so much !

Excellent :slight_smile:

I’ve confirmed that a clean LXD still will not let you use a relative source, so hopefully this won’t be a problem again :slight_smile:
