問題

コマンドstorage aggregate add-disks -aggregate -simulateを実行して既存のミラーアグリゲートにディスクを追加する場合、最初のプレックスのディスク数と 2 番目のプレックスの数が異なって表示されます。

次のコマンドは、既存のアグリゲート「 aggr_SSD 」に 11 本のディスクを追加しています。

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.
