Hi all,
I've had a crash on my NAS and since then one of my drives will not import. They are all single drive ZFS pools at this point so structurally more simple than any RAID configs.
Attempting an import from the command line returns UNAVAIL cannot open but gpart shows the drive and its partitions appear intact. zdb -l /dev/ada0 shows label 0 cannot be unpacked but the other three are fine.
Is there any hope in resolving or is this looking a little bleak ?
Output from zpool import, gpart and zdb -l follow.
Tristan.
