The message "last accessed on another system" is the normal behavior if the pool is ungracefully offlined for some reason, and then you boot back up again on the same system. I learned that by using a pool on an external disk, and accidentally knocking out the power cord of the external disk. The system hung. I power cycled, couldn't boot normal. Had to boot failsafe, and got the above message while trying to import. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] is this pool recoverable?
Patrick, I'm happy that you were able to recover your pool. Your original zpool status says that this pool was last accessed on another system, which I believe is what caused of the pool to fail, particularly if it was accessed simultaneously from two systems. It is important that the cause of the original pool failure is identified to prevent it from happening again. This rewind pool recovery is a last-ditch effort and might not recover all broken pools.

It looks like it wants you to use both -f and -F at the same time. I don't see that you tried that. Good luck.
