[zfs-discuss] zpool replace

2011-08-15 Thread Doug Schwabauer


  
  
Help - I've got a bad disk in a zpool and need to replace it. I've
got
an extra drive that's not being used, although it's still marked
like
it's in a pool. So I need to get the "xvm" pool destroyed, c0t5d0
marked as available, and replace c0t3d0 with c0t5d0.

root@kc-x4450a # zpool status -xv
 pool: vms
state: UNAVAIL
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run
'zpool
clear'.
 see: http://www.sun.com/msg/ZFS-8000-HC
scrub: none requested
config:

 NAME STATE READ WRITE CKSUM
 vms UNAVAIL 0 3 0 insufficient

 c0t2d0 ONLINE 0 0 0

  suspended
root@kc-x4450a # zpool import

state: DEGRADED
status: The pool was last accessed by another system.
action: The pool can be imported despite missing or damaged
devices.
The
 fault tolerance of the pool may be compromised if imported.

Thanks!

[zfs-discuss] reset a disk?

2007-12-12 Thread Doug Schwabauer
I can't find how to do this...I used a disk for a zfs pool and now I 
want to use it for normal UFS stuff.  But my partition table now looks like:

Part  TagFlag First SectorSizeLast Sector
  0usrwm34  33.91GB 71116541
  1 unassignedwm 0  0  0
  2 unassignedwm 0  0  0
  3 unassignedwm 0  0  0
  4 unassignedwm 0  0  0
  5 unassignedwm 0  0  0
  6 unassignedwm 0  0  0
  8   reservedwm  71116542   8.00MB 71132925

I'm assuming zpool did this when I used the disk device c1t1d0 instead 
of the c1t1d0s2 partition?  How do I release or reset this disk so I get 
the normal 0-7 partitions?  I've already destroyed the pool.
