I have a machine that had some trouble with some bad RAM. After I diagnosed it and removed the offending stick of RAM, The ZFS pool in the machine was trying to access drives by using incorrect device names. I simply exported the pool and re-imported it to correct this. However I am now getting this error.

The pool Storage no longer automatically mounts

sqeaky@sqeaky-media-server:/$ sudo zpool status
no pools available

A regular import says its corrupt

sqeaky@sqeaky-media-server:/$ sudo zpool import
  pool: Storage
    id: 13247750448079582452
 state: UNAVAIL
status: The pool is formatted using an older on-disk version.
action: The pool cannot be imported due to damaged devices or data.
config:

    Storage                 UNAVAIL  insufficient replicas
      raidz1                UNAVAIL  corrupted data
        805066522130738790  ONLINE
        sdd3                ONLINE
        sda3                ONLINE
        sdc                 ONLINE

A specific import says the vdev configuration is invalid

sqeaky@sqeaky-media-server:/$ sudo zpool import Storage
cannot import 'Storage': invalid vdev configuration

I should have 4 devices in my ZFS pool: /dev/sda3 /dev/sdd3 /dev/sdc /dev/sdb

I have no clue what 805066522130738790 is but I plan on investigating further. I am also trying to figure out how to use zdb to get more information about what the pool thinks is going on.

For reference This was setup this way, because at the time this machine/pool was setup it needed certain Linux features and booting from ZFS wasn't yet supported in Linux. The partitions sda1 and sdd1 are in a raid 1 for the operating system and sdd2 and sda2 are in a raid1 for the swap.

Any clue on how to recover this ZFS pool?
