zfs mounted filesystem doesn't show up

[Rob Rati]

I have 2 systems running zfs, and one back up to the other by taking a snapshot and sending it to the other.  The data and snapshot information all appear in the 2nd system, but the directories aren't accessible from the command line despite being mounted.  If I do a mount I see this:

pool/host/root on /pool/host/root (zfs, local, nfsv4acls)

But I can't list or cd into /pool/host/root.  However, if I zfs umount /pool/host/root then zfs mount /pool/host/root everything is fine and I can see the data.  This seems to be occurring every time the first system backs up to the second.

Any ideas?
