so ... i hate USB as well. i guess i''ll have to get a SAS or fibre
enclosure. (even though i only need USB2 performance.)
i hot plugged a drive into my USB2 enclosure. i was adding and removing
drives earlier just fine, but this time all (both) disks in the enclosure
became unavailable. i don''t really know yet if this was a solaris
problem or an enclosure problem.
i ran ''reboot'' which hung Solaris at the "updating boot
archive" so i
had to power cycle the machine. when it comes back up,
''rmformat'' only
sees one of the drives, which has (had) a 1-disk zpool on it.
pool: data2
state: UNAVAIL
status: One or more devices could not be opened. There are insufficient
replicas for the pool to continue functioning.
action: Attach the missing device and online it using ''zpool
online''.
see: http://www.sun.com/msg/ZFS-8000-3C
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
data2 UNAVAIL 0 0 0 insufficient replicas
c3t0d0 UNAVAIL 0 0 0 cannot open
i''ve tried various things but am unable to get this pool to import.
there
ARE no other disks in the pool, so not sure how there can be "insufficient
replicas". it was working just fine as a 1-disk zpool before the reboot.
in fact, there is another 1-disk zpool active right now.
or is it the case that solaris is telling me it knows about this data2
pool that used to exist, but it can''t physically find the drive? i
don''t
think that''s it, because ''rmformat'' shows the drive.

Most of them are cosmetic, which is why (IMHO) it has not been a high priority. I meant to track a bunch of these down and add them to the ZFS Troubleshooting Guide. -- richard
