Autodefrag shouldn't have any snapshots mount-time-related interaction, with snapshot-aware-defrag disabled. The interaction between defrag (auto or not) and snapshots will be additional data space usage, since with snapshot-aware disabled, defrag only works with the current copy, thus forcing it to COW the extents elsewhere while not freeing the old extents as they're still referenced by the snapshots, but it shouldn't affect mount-time. -- Duncan - List replies preferred.
