Issue

  • More than two disks pre-failed in the same RAID group. Example:

Aggregate node_name_aggr1 (online, raid_dp) (block checksums)
  Plex /node_name_aggr1/plex0 (online, normal, active, pool0)
    RAID group /node_name_aggr1/plex0/rg0 (normal, block checksums) 
      RAID Disk Device   HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)    Phys (MB/blks)
      --------- ------   ------------- ---- ---- ---- ----- --------------    --------------
