We updated our 2.9 LFS to zfs 0.7 and lustre 2.10 and we see the same thing when mounting the MDT and OST's on the servers – for both the primary lustre MDT/OST devices and snapshots. Here is an example with a snapshot.

The second OSS already got zfs-0.7, so I created new Lustre modules. Both went fine. Of course I was curious about what happens when updating ZFS-beneath-Lustre, so I did that on the first OSS. Again everything fine - except that the successful 'mount -t lustre...' ends with a funny error message >> mount.lustre FATAL: unhandled/unloaded fs type 0 'ext3' So far I see no problems with these OSTs. May not be connected to updating zfs, of course.
