LXD 5.14 in both sides with ZFS.
I use copy --refresh to backup containers daily.
After a network failure during a lxc copy --refresh, my target instance was deleted on ZFS. Repeating the command:
lxc copy cb2:zammad zammad-backup --refresh
Error: Failed instance creation: Error transferring instance data: Failed migration on target: Failed creating instance on target: Volume exists in database but not on storage
To correct, I need to remove this target machine and copy all again.
It’s easy to reproduce, interrupting communication while in copy.
