ZFS weird issue...

Here's what happened:

LSI9260-16i, 16x3T SATA drives.  15 LDs each configured as single disk
RAID0 last drive a hot spare.

All LDs configured as a ZFS RaidZ2 pool ('sorbs')

Bay/Drive 8 failed, hot spare kicked in.  ZFS resilvered. (mfid15 became
spare-8)

On reboot mfid9-15 were re-named automatically to mfid8-14 ... ZFS
didn't seems to care...

Days later new drive to replace the dead drive arrived and was
inserted.  System refused to re-add as there was data in the cache, so
rebooted and cleared the cache (as per many on web faq's)  Reconfigured
it to match the others.  Can't do a zpool replace mfid8 because that's
already in the pool... (was mfid9) can't use mfid15 because zpool
reports it's not part of the config... can't use the uniq-id it received
(can't find vdev) ... HELP!! :)

This is what I can see currently ...

Thanks, in advance.
