问题

聚合的 RAID 组处于联机状态，但已降级。要进行识别，请在 MetroCluster 中的每个节点上运行 sysconfig -r 命令。

node run -node * -command sysconfig -r

Aggregate aggr0 (online, raid4, degraded, mirrored) (block checksums) Plex /aggr0/plex0 (online, normal, active, pool0) RAID group /aggr0/plex0/rg0 (normal, block checksums) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity switch1:8.217L2 1a 10 1 FC:A 0 SSD N/A 915465/1874872832 915715/1875385008 data switch3:8.217L3 1a 10 2 FC:A 0 SSD N/A 915465/1874872832 915715/1875385008 Plex /aggr0/plex1 (online, normal, active, pool1) RAID group /aggr0/plex1/rg0 (degraded, block checksums) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity switch2:8.217L2 1c 20 7 FC:B 1 SSD N/A 915465/1874872832 915715/1875385008 data switch4:8.217L3 1a 20 6 FC:A 1 SSD N/A 915465/1874872832 915715/1875385008 (offline)

在以上示例中，aggr0 具有降级的 plex1。
