Re: [zfs-discuss] how to destroy a pool by id?
Hi Chris, Yes, this is a known problem and a CR is filed. I haven't tried these in a while, but consider one of the following workarounds below. #1 is most drastic and make sure you've got the right device name. No sanity checking is done by the dd command. Other experts can comment on a better dd command. Thanks, Cindy 1. Wipe the disk label with a dd command. For example: dd if=/dev/zero of=/dev/dsk/c1t0d0s0 count=100 bs=512k (The following two probably won't work if you're getting device in use messages.) 2. Force the creation of a new pool on the disk, like this: # zpool create -f pool ct1d0 Then, remove the new pool: # zpool destroy pool 3. Put the opposite label on the disk. If the disk has an SMI label, use format -e to force an EFI label. Or, vice versa. On 02/12/11 03:33, chris wrote: I have old pool skeletons with vdevs that no longer exist.

Re: [zfs-discuss] how to destroy a pool by id?
Hi Kent, This is what I do in similar situations: 1. Import the pool to be destroyed by using the ID. In your case, like this: # zpool import 3280066346390919920 If tank already exists you can also rename it: # zpool import 3280066346390919920 tank2 Then destroy it: # zpool destroy tank2 I wish we had a zpool destroy option like this: # zpool destroy -really_dead tank2 Cindy - Original Message - From: Kent Watsen Date: Saturday, June 20, 2009 3:02 pm Subject: [zfs-discuss] how to destroy a pool by id?

[zfs-discuss] how to destroy a pool by id?
Over the course of multiple OpenSolaris installs , I first created a pool called "tank" and then, later and resusing some of the same drives, I created another pool called tank. I can `zpool export tank`, but when I `zpool import tank`, I get: bash-3.2# zpool import tank cannot import 'tank': more than one matching pool import by numeric ID instead Then, using just `zpool import` I see the IDs: bash-3.2# zpool import pool: tank id: 15608629750614119537 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: tank ONLINE raidz2 ONLINE c3t0d0 ONLINE c3t4d0 ONLINE c4t0d0 ONLINE c4t4d0 ONLINE c5t0d0 ONLINE c5t4d0 ONLINE raidz2 ONLINE c3t1d0 ONLINE c3t5d0 ONLINE c4t1d0 ONLINE c4t5d0 ONLINE c5t1d0 ONLINE c5t5d0 ONLINE pool: tank id: 3280066346390919920 state: ONLINE status: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and the '-f' flag. see: http://www.sun.com/msg/ZFS-8000-EY config: tank ONLINE raidz2 ONLINE c4t1d0p0 ONLINE c3t1d0p0 ONLINE c4t4d0p0 ONLINE c3t4d0p0 ONLINE c3t5d0p0 ONLINE c3t0d0p0 ONLINE How can I destroy the pool 3280066346390919920 so I do have to specify the ID to import tank in the future?
