``me, too'' with b71, so the symptom isn't new.
I think this happens for me when the pool is UNAVAILABLE at boot, and
then enough devices come on line that it becomes ready. In that case
I need to do both zfs mount -a and zfs share -a. (or export/import)
For me the main aspect of this problem is zfs mount mounting things in
the wrong order: some of the datasets are mounted but not all. If you
have nested filesystems,
a/A
a/A/1
a/A/2
a/B
sometimes you can end up with a/A/1, a/A/2, a/B mounted but a/A is not
mounted. In this case, the 'a' filesystem contains empty directories
serving as mountpoints a/A/1 and a/A/2, when it should contain only
mountpoint a/A (with the deeper two mountpoints inside the a/A
filesystem). You have to clear out the incorrect deeper mountpoints
before zfs mount -a will work properly again.
so on second thought since you say none of your filesystems are
mounted, you may have a different symptom.
