I did the scrub after the first couple panics. So after the corruption
had already happened.

It's a backup server with 16TB sitting on it with only a top level
filesystem. I can move the parent directories of the corrupt file around,
at least within the same filesystem. I believe that moving it to a new
filesystem will require ZFS to read the file (and xattrs) in order to
write them in the new filesystem. I would be shocked if this does not
crash the box, but I will give it a try when I get a chance.
