zfs discuss - May 2006 - Borked zpool is now invulnerable

Hello,

while testing some code changes, I managed to fail an assertion while
doing a zfs create.

My zpool is now invulnerable to destruction. :(

bash-3.00# zpool destroy -f test_undo
internal error: unexpected error 0 at line 298 of ../common/libzfs_dataset.c

bash-3.00# zpool status
  pool: test_undo
 state: ONLINE
 scrub: none requested
config:

        NAME        STATE     READ WRITE CKSUM
        test_undo   ONLINE       0     0     0
          c0d1s1    ONLINE       0     0     0
          c0d1s0    ONLINE       0     0     0

errors: No known data errors

How can I destroy this pool so I can use the disk for a new pool? Thanks! :)

dd if=/dev/zero of=/dev/dsk/c0d1s1
dd if=/dev/zero of=/dev/dsk/c0d1s0

that should do it.

Nifty - does that mean your disk is also invulnerable to hardware errors
too ? [ as in, your typical superhero who gets endowed with special
abilities due to a failed radiation experiment  ;-) ]

I''d suggest zpool exporting all other pools on the system, then reboot
into failsafe mode, mount your root partition somewhere (like /tmp/a)
then remove /tmp/a/etc/zfs/zpool.cache. Finally, reboot and create a new
pool on the disk which has now been made available, and then zpool
import the others.

Hope that helps (all disclaimers about making backups of anything you
care about before doing this sort of thing apply)

Anyone know of a simpler way ?
