How can I get rid of the UNAVAIL disk slice so that this pool doesn't
try to resilver (From what, pray tell?) all the time.  I don't know
where that ugly number came from--this system only has SATA disks.  I
have a new mirror slice just waiting for it as soon as it stops doing
this.  zpool clear  just hangs. Meanwhile, despite its assertions of
ONLINE,

# zfs list -r cloaking
cannot open 'cloaking': pool I/O is currently suspended
# zpool remove cloaking 8647373200783277078
cannot remove 8647373200783277078: only inactive hot spares, cache, top-level, or log devices can be removed
# zpool offline cloaking 8647373200783277078
cannot offline 8647373200783277078: pool I/O is currently suspended
# 

I'm of the opinion that the data is mostly intact (unless zpool has been
tricked into resilvering a data disk from a blank one (horrors)).

# zpool export cloaking

hangs.
