I can't export one of the pools. Here is the zpool status -x output for
reference:
# zpool status -x
pool: zs-scat-dmz
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

I find that appending s0 to the device gives me better information:
