Hi Daniel

Thanks for your comments, this was not the issue. All the subvols have
mount points.

BUT

I did find the issue, I had a fstab entry which was doing a bind from
the rbd to a normal path location

This was causing the zfs mount service to fail because it thought the
rbd had files in it.

Removed this by changing the service to use the rbd directory directly
instead of a bind.


Cheers
