I get the following output when i run a zpool status , but i am a little
confused of why c9t8d0 is more "left align" then the rest of the disks
in the pool , what does it mean ?
$ zpool status blmpool
pool: blmpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
blmpool ONLINE 0 0 0
raidz2 ONLINE 0 0 0
c9t0d0 ONLINE 0 0 0
c9t1d0 ONLINE 0 0 0

Your pool is "bad", as c9t8d0 is without redundancy. If it fails, your pool is toast. zpool history should be able to tell when it happened at least.> $ zpool status blmpool > pool: blmpool > state: ONLINE > scrub: none requested > config: > > NAME STATE READ WRITE CKSUM > blmpool ONLINE 0 0 0 > raidz2 ONLINE 0 0 0 > c9t0d0 ONLINE 0 0 0 > c9t1d0 ONLINE 0 0 0 > c9t3d0 ONLINE 0 0 0 > c9t4d0 ONLINE 0 0 0 > c9t5d0 ONLINE 0 0 0 > c9t6d0 ONLINE 0 0 0 > c9t7d0 ONLINE 0 0 0 > c9t8d0 ONLINE 0 0 0 > -- > This message posted from opensolaris.org > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss/Tomas -- Tomas ?gren, stric at acc.umu.se, http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Ume? `- Sysadmin at {cs,acc}.umu.se

Basically you have two top-level vdevs: one is your raidz2 vdev containing 7 disks, and another one single disk top-level vdev c9t8d0. I guess it was added like this "zpool add -f blmpool c9t8d0". Without -f it would complain about mismatching replication levels. You can check pool history to see when exactly it was done.> > $ zpool status blmpool > pool: blmpool > state: ONLINE > scrub: none requested > config: > > NAME STATE READ WRITE CKSUM > blmpool ONLINE 0 0 0 > raidz2 ONLINE 0 0 0 > c9t0d0 ONLINE 0 0 0 > c9t1d0 ONLINE 0 0 0 > c9t3d0 ONLINE 0 0 0 > c9t4d0 ONLINE 0 0 0 > c9t5d0 ONLINE 0 0 0 > c9t6d0 ONLINE 0 0 0 > c9t7d0 ONLINE 0 0 0 > c9t8d0 ONLINE 0 0 0 > -- > This message posted from opensolaris.org > _______________________________________________ > zfs-discuss mailing list > zfs-discuss at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
thanks for the quick responses and yes the history show just what you said :( is there a way i can get c9t8d0 out of the pool , or how do i get the pool back to optimal redundancy ? -- This message posted from opensolaris.org

Or if that isn''t an option, attach a mirror deive to c9t8d0. -- Ian.

When the mythical bp_rewrite shows up, then you can. For now, the only thing you can do to save your pool is attach another disk (or two) as a mirror. -B -- Brandon High : bhigh at freaks.com
