[lxc-users] zfs @copy snapshots

[Kees Bos]

Thanks a lot.

It looks like that these @copy are left overs from failed container
snapshots. I'm creating an destroying snapshots via the api (pylxd) and
I've seen @copy snapshots at creation time where I expected a @snapshot
zfs snapshot. I'm now destroying these @copy snapshots automatically
(which most of the time succeeds, every now and then there's still a
@snaphot dependency that blocks the destroy).
