问题

执行命令 "storage aggregate add-disks -aggregate -simulate" 向现有镜像聚合添加磁盘时,第一个丛的磁盘计数与第二个丛显示不同的数字。

示例

以下命令将 11 个磁盘添加到现有聚合 "aggr_SSD" 中:

Cluster::> storage aggregate add-disks -aggregate aggr_ssd -disklist 1.31.12,1.31.13,1.31.14,1.31.15,1.31.16,1.31.17,1.31.18,1.31.19,1.31.20,1.31.21,1.31.22 -raidgroup rg0 -mirror-disklist 4.21.12,4.21.13,4.21.14,4.21.15,4.21.16,4.21.17,4.21.18,4.21.19,4.21.20,4.21.21,4.21.22 -simulate

Disks would be added to aggregate "aggr_ssd" on node "Cluster_node1" in the following manner:

First Plex

RAID Group rg0, 22 disks (block checksum, raid_dp)
Usable Physical
Position Disk Type Size Size
---------- ------------------------- ---------- -------- --------
data 1.31.12 SSD 3.49TB 3.49TB
data 1.31.13 SSD 3.49TB 3.49TB
data 1.31.14 SSD 3.49TB 3.49TB
data 1.31.15 SSD 3.49TB 3.49TB
data 1.31.16 SSD 3.49TB 3.49TB
data 1.31.17 SSD 3.49TB 3.49TB
data 1.31.18 SSD 3.49TB 3.49TB
data 1.31.19 SSD 3.49TB 3.49TB
data 1.31.20 SSD 3.49TB 3.49TB
data 1.31.21 SSD 3.49TB 3.49TB
data 1.31.22 SSD 3.49TB 3.49TB

Second Plex

RAID Group rg0, 11 disks (block checksum, raid_dp)
Usable Physical
Position Disk Type Size Size
---------- ------------------------- ---------- -------- --------
data 4.21.12 SSD 3.49TB 3.49TB
data 4.21.13 SSD 3.49TB 3.49TB
data 4.21.14 SSD 3.49TB 3.49TB
data 4.21.15 SSD 3.49TB 3.49TB
data 4.21.16 SSD 3.49TB 3.49TB
data 4.21.17 SSD 3.49TB 3.49TB
data 4.21.18 SSD 3.49TB 3.49TB
data 4.21.19 SSD 3.49TB 3.49TB
data 4.21.20 SSD 3.49TB 3.49TB
data 4.21.21 SSD 3.49TB 3.49TB
data 4.21.22 SSD 3.49TB 3.49TB

Aggregate capacity available for volume use would be increased by 32.85TB.
