Disks with wrong GUID in labels
Something happened with one of my controllers and I now have an un-importable pool. The issue that I am seeing is that when certain disks are connected, they show up in the pool device list twice. One ONLINE and one UNAVAIL. For example:
    NAME                       STATE
    root                       UNAVAIL
      raidz2-0                 UNAVAIL
        c0t5000C500C5202E8Ad0  REMOVED
        c0t5000C500C540ED27d0  UNAVAIL
        c0t5000C500C540ED27d0  ONLINE
        c0t5000C500C540ACB3d0  REMOVED
        c2t3d0                 ONLINE
        c2t2d0                 ONLINE
        c2t0d0                 ONLINE
Notice the two instances of c0t5000C500C540ED27d0. One of those is hiding the actual other device (c0t5000C500C5202BEBd0).
