问题描述

修复数据和根聚合后,其中一个根聚合磁盘不会返回到正在等待切回的节点:
 
示例:
 
  • 在聚合修复之后从灾难站点角度查看根聚合

  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/ -

 

  • 恢复故障驱动器后根聚合的 Active Site 视角:

  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
