deswizzle restarts on each snapmirror update, so to check if deswizzle is running behind, make sure `wafl scan status` shows no deswizzles running before the next snapmirror update.

To my knowledge there's no way to understand the ETA (for finish) of a deswizzler WAFL scanner. It depends, on a few factors. The major one is the inode density -- it walks inodes...

This is not in any way an answer or a clue to Jeff's original Q:

Is there a way to tell how many snapmirror updates behind deswizzle is?

But still :-)

You can check what snapshot deswizzle is working on by using `snap status` to get the snapid, but it should always be on the last snapmirror snapshot.
