I agree with you, but until now all of the scrubs have only shown errors on the 
oldest snapshot, not on the underlying filesystem.  I don't doubt the same file 
was in an error condition on the filesystem, but it was odd that zpool status 
was only showing the errors on the snapshot.  Oddly, now zpool status is 
showing errors on the files themselves too.

It was also unfortunate that the zfs send/receive would hang and even the zpool 
and zfs command would hang when working with those pools/datasets.

I guess the reason I was posting is I was looking for the right "manual 
intervention" (which may be restoring or deleting the files and then removing 
all snapshots?) and the hanging behavior of zpool and zfs send seemed somewhat 
disconcerting.  They would even block the system from both "init 5" and "reboot 
-n".  

The reality with all of these files is that I either have them elsewhere or 
they can be safely deleted since they're easily recreated.  I'll try removing 
all of the snapshots, then recover/delete the underlying files, then run 
another scrub.
