Steps

之前:

ssh登录:

./MegaCli64 -LDInfo -LALL -aAll查看VD信息， 其中VD0（600G）不需要动.

./MegaCli64 -PDList -aAll | grep -i adapter得到adapter数值:

删除VD1-VD3:

# ./MegaCli64 -cfglddel -L1 -a0
# ./MegaCli64 -cfglddel -L2 -a0
# ./MegaCli64 -cfglddel -L3 -a0

当前VD：

查看PD对应磁盘:

# ./MegaCli64 -PDList -aAll | more
两个600G的是0和1, 其他的随便动

查看多少块盘:

# ./MegaCli64 -PDList -aAll |  grep 'Slot Number'

这里注意,2,3 是没有，从4~27为slot number.

得到Enclosure ID:

# ./MegaCli64 -PDList -aAll | grep 'Enclosure'
为9

开始做24个raid0:

# ./MegaCli64 -CfgLdAdd -r0 [9:4] -a0
# ./MegaCli64 -CfgLdAdd -r0 [9:5] -a0
......
# ./MegaCli64 -CfgLdAdd -r0 [9:26] -a0
# ./MegaCli64 -CfgLdAdd -r0 [9:27] -a0

脚本:

lsblk查看磁盘信息:

删除多余分区, sdb/sdn/sdr:

add zfs pool

命令行下添加:

# zpool create -f -o ashift=12 vmpool raidz2 /dev/sdb /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg /dev/sdh /dev/sdi
# zpool add -f -o ashift=12 vmpool raidz2 /dev/sdj /dev/sdk /dev/sdl /dev/sdm /dev/sdn /dev/sdo /dev/sdp /dev/sdq
# zpool add -f -o ashift=12 vmpool raidz2 /dev/sdr /dev/sds /dev/sdt /dev/sdu /dev/sdv /dev/sdw /dev/sdx /dev/sdy
# zpool list
