[zfs-discuss] Recover data from detached ZFS mirror
Does anyone know where the Jeff Bonwick tool to recover a ZFS label is? The old link was: http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg15620.html But it does not exist anymore. I have a zfs detached disk that was part of a root mirror and I need to boot from it. Thank you for any information. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Recover data from detached ZFS mirror
Hi Judy, Without much to go on, let's try the easier task first. Is it possible that you can re-attach the detached disk back to original root mirror disk?

Re: [zfs-discuss] Recover data from detached ZFS mirror
Hi Cindy, Well, the other half of the zfs mirror is on a truck via snail mail to another location. We thought we were saving a copy of the root disk when we did a zfs detach. We didn't know it would remove the zfs label information. Is there a way to get the disk back to a bootable state? Thanks, --Judy-- Hi Judy, Without much to go on, let's try the easier task first.

Re: [zfs-discuss] Recover data from detached ZFS mirror
Hi Judy, The disk label of the detached disk is intact but the pool info is no longer accessible so no easy way exists to solve this problem. Its not simply a matter of getting the boot info back on there, its the pool info. Your disk will have to meet up with its other half before it can be bootable again is my assessment. Many experts are on this list so maybe they will have a suggestion.
