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.
