I can observer a similar problem where I can not list .zfs directory under filesystems which do not have any snapshots. I can not tell if the problem happens when all snapshots are removed or if it only happens if a filesystem doesn't have any snapshots when ZFS is initialized (a system is booted). I am not sure what's going on but a quick check with DTrace points to negative caching as a culprit. I see that cache_lookup() returns ENOENT for .zfs. -- Andriy Gapon
