Issue

After healing the data and root aggregates, one of the root aggregate disks is not returned to the node that is waiting for switchback:
 
Example:
 
  • Disaster Site perspective of root aggregate after aggregate healing

  Plex /DisasterSite_root/plex0 (online, normal, active, pool0)
    RAID group /DisasterSite_root/plex0/rg0 (degraded, block checksums)

      RAID Disk    Device         HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)    Phys (MB/blks)
      ---------    ------         ------------- ---- ---- ---- ----- --------------    --------------
      dparity      4b.125L1027    4b    50  0   FC:B   0  BSAS  7200 1695466/3472315904 1695759/3472914816 
      parity       4b.125L1028    4b    50  1   FC:B   0  BSAS  7200 1695466/3472315904 1695759/3472914816 
      data         FAILED                 N/A                        1695466/ -

 

  • Active Site perspective of root aggregate after the failed drive was recovered:

  Plex /DisasterSite_root/plex0 (online, normal, active, pool0)
    RAID group /DisasterSite_root/plex0/rg0 (double degraded, block checksums)

      RAID Disk    Device         HA  SHELF BAY CHAN Pool Type  RPM  Used (MB/blks)    Phys (MB/blks)
      ---------    ------         ------------- ---- ---- ---- ----- --------------    --------------
      dparity      FAILED                 N/A                        1695466/ -
      parity       FAILED                 N/A                        1695466/ -
      data         4b.125L1029    4b    50  2   FC:B   0  BSAS  7200 1695466/3472315904 1695759/3472914816
