Hi all,
After shuffling some disks around in a ZFS array (moving them to a
hot-swap cabinet) I am now seeing gptid numbers when doing a zpool
status:
zpool status schtuff
pool: schtuff
state: ONLINE
scan: scrub repaired 0 in 5h57m with 0 errors on Wed Jul 20 17:05:29 2011
config:
NAME STATE READ

schtuff ONLINE 0

raidz1-0 ONLINE 0

gptid/13aed7e6-9ca8-11e0-99f1-001a4d9c179c ONLINE 0

gptid/15c300de-9ca8-11e0-99f1-001a4d9c179c ONLINE 0
0 0
errors: No known data errors
Now this is all very interesting, but I would like to be able to map
that back to a /dev/adXpY device entry, so when I offline them I can
then go to the appropriate physical disk. I thought that gpart show -r
might help, but the numbers emitted from that don't match up. Looking
at the major/minor numbers of the devices don't help either. Does
anyone have an idea?
Stephen
