Also can someone tell me if I'm too late for an uberblock rollback to help me?
Diffing "zdb -l" output between c7t0 and c7t1 I see:
- txg=12968048
+ txg=12968082
Is that too large a txg gap to roll back, or is it still possible?

hot plugging the disks, I get:

OK, things are now different (possibly better?):

I suspect that an uberblock rollback might help me - googling all the
references now, but if someone has any advice, I'd be grateful.
And I'm afraid I just did something foolish. zdb wasn't working, so I
tried exporting the pool. Now I'm back to:
bash-3.2# /usr/sbin/zpool import
pool: media
id: 4928877878517118807
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.
see: http://www.sun.com/msg/ZFS-8000-3C
config:
media UNAVAIL insufficient replicas
raidz1 UNAVAIL insufficient replicas
c7t5d0 UNAVAIL cannot open
c7t2d0 ONLINE
c7t4d0 ONLINE
c7t3d0 ONLINE
c7t0d0 OFFLINE
c7t7d0 ONLINE
c7t1d0 ONLINE
c7t6d0 ONLINE
Can anyone help me get c7t0d0 "ONLINE" and roll back the uberblocks so I
can import the pool and save my data?
