問題

新しいアグリゲートと同じ数のディスクで作成した新しいRAIDグループでボリュームに使用できるアグリゲート容量が異なります

cluster::> aggr create -aggregate aggr02 -diskcount 12 -mirror true -simulate true -node cluster-01 The layout for aggregate "aggr02" on node "cluster-01" would be: First Plex RAID Group rg0, 6 disks (block checksum, raid_dp) Usable Physical Position Disk Type Size Size ---------- ------------------------- ---------- -------- -------- shared 1.0.13 SSD-NVM - - shared 1.2.4 SSD-NVM - - shared 1.2.5 SSD-NVM 3.48TB 3.48TB shared 1.2.6 SSD-NVM 3.48TB 3.48TB shared 1.2.7 SSD-NVM 3.48TB 3.48TB shared 1.2.8 SSD-NVM 3.48TB 3.48TB Second Plex RAID Group rg0, 6 disks (block checksum, raid_dp) Usable Physical Position Disk Type Size Size ---------- ------------------------- ---------- -------- -------- shared 2.1.23 SSD-NVM - - shared 2.2.4 SSD-NVM - - shared 2.2.5 SSD-NVM 3.48TB 3.48TB shared 2.2.6 SSD-NVM 3.48TB 3.48TB shared 2.2.7 SSD-NVM 3.48TB 3.48TB shared 2.2.8 SSD-NVM 3.48TB 3.48TB Aggregate capacity available for volume use would be 11.91TB.

cluster::> aggr add-disks -aggregate aggr01 -diskcount 12 -simulate true Disks would be added to aggregate "aggr01" on node "cluster-01" in the following manner: First Plex RAID Group rg1, 6 disks (block checksum, raid_dp) Usable Physical Position Disk Type Size Size ---------- ------------------------- ---------- -------- -------- shared 1.0.13 SSD-NVM - - shared 1.2.4 SSD-NVM - - shared 1.2.5 SSD-NVM 3.48TB 3.48TB shared 1.2.6 SSD-NVM 3.48TB 3.48TB shared 1.2.7 SSD-NVM 3.48TB 3.48TB shared 1.2.8 SSD-NVM 3.48TB 3.48TB Second Plex RAID Group rg1, 6 disks (block checksum, raid_dp) Usable Physical Position Disk Type Size Size ---------- ------------------------- ---------- -------- -------- shared 2.1.23 SSD-NVM - - shared 2.2.4 SSD-NVM - - shared 2.2.5 SSD-NVM 3.48TB 3.48TB shared 2.2.6 SSD-NVM 3.48TB 3.48TB shared 2.2.7 SSD-NVM 3.48TB 3.48TB shared 2.2.8 SSD-NVM 3.48TB 3.48TB Aggregate capacity available for volume use would be increased by 12.57TB.
