The LUN id is the last number of 2:0:0:x or 1:0:0:x.
The order should be mpatha, mpathb, mpathd, mpathc.
# vgcreate VGMD1 /dev/mapper/mpatha /dev/mapper/mpathb /dev/mapper/mpathd
/dev/mapper/mpathc
d. Create logic volume.
# lvcreate -i 4 -I 1024 -l 100%FREE VGMD1 -n LVMD1
e. Create XFS file system.
# mkfs.xfs -l size=128m /dev/VGMD1/LVMD1
f. Mount XFS file system.
# mount -o noatime,allocsize=1g,nobarrier,inode64,logbsize=262144,wsync
/dev/VGMD1/LVMD1 /mnt/xfs1/
Make sure the above commands can be executed successfully, then unmount XFS on /mnt/xfs1.
g. Unmount XFS file system.
# umount /mnt/xfs1
h. Go to step 6 in section A.7.2 to resume the HA cluster configuration.
Configure 288TB storage array
For 288TB storage array configuration, it is very similar to the 144TB storage array configuration.
The difference is that 288TB configuration requires performing 144TB configuration first, then
extending the configuration to 288TB.
# pvcreate /dev/mapper/mpatha /dev/mapper/mpathb /dev/mapper/mpathc
/dev/mapper/mpathd /dev/mapper/mpathe /dev/mapper/mpathf
/dev/mapper/mpathg /dev/mapper/mpathh
Note: different mpath names may be observed according to the actual configuration, please modify
them before executing pvcreate.
For creating volume group, pay attention to the order of physical volumes, make sure they follow
the order of LUN ids (from small to large).
