问题描述

一个数据混合聚合、其中包含少于4个SSD RAID组。示例：

Aggregate aggregate (online, mixed_raid_type, hybrid) (block checksums) Plex /aggregate/plex0 (online, normal, active, pool0) RAID group /aggregate/plex0/rg0 (normal, block checksums, raid_dp) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- dparity 0a.00.4P1 0a 0 4 SA:A 0 SAS 10000 793908/1625923584 793916/1625939968 parity 0a.00.6P1 0a 0 6 SA:A 0 SAS 10000 793908/1625923584 793916/1625939968 data 0a.00.8P1 0a 0 8 SA:A 0 SAS 10000 793908/1625923584 793916/1625939968 ... data 0b.00.21P1 0b 0 21 SA:B 0 SAS 10000 793908/1625923584 793916/1625939968 RAID group /aggregate/plex0/rg1 (normal, block checksums, raid4) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity 0b.00.3P1 0b 0 3 SA:B 0 SSD N/A 95312/195200512 95320/195216896 data 0a.00.2P1 0a 0 2 SA:A 0 SSD N/A 95312/195200512 95320/195216896 data 0b.00.1P1 0b 0 1 SA:B 0 SSD N/A 95312/195200512 95320/195216896 RAID group /aggregate/plex0/rg2 (normal, block checksums, raid4) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity 0b.00.3P2 0b 0 3 SA:B 0 SSD N/A 95312/195200512 95320/195216896 data 0a.00.2P2 0a 0 2 SA:A 0 SSD N/A 95312/195200512 95320/195216896 data 0b.00.1P2 0b 0 1 SA:B 0 SSD N/A 95312/195200512 95320/195216896 RAID group /aggregate/plex0/rg3 (normal, block checksums, raid4) RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- parity 0b.00.3P3 0b 0 3 SA:B 0 SSD N/A 95312/195200512 95320/195216896 data 0a.00.2P3 0a 0 2 SA:A 0 SSD N/A 95312/195200512 95320/195216896 data 0b.00.1P3 0b 0 1 SA:B 0 SSD N/A 95312/195200512 95320/195216896

这些SSD的可用备用分区。示例：
