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)
