Issue

  • Reconstruction only occurring on a single RAID group while the others remain idle:
Aggregate aggr2 (online, raid_dp, reconstruct, fast zeroed) (block checksums)
  Plex /aggrb/plex0 (online, normal, active, pool0)
    RAID group /aggrb/plex0/rg0 (reconstruction 16% completed, block checksums)
      RAID Disk    Device         HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)    Phys (MB/blks)
