In situation where you need to add new physical storage into an LVM volume, you're essentially extending the LVM volume. This guide shows you how to extend the LVM volume when a new storage disk is available for extension.
Before starting to extend a logical volume, it is always good to check the LVM volume status for available free space and label for correct LVM volume.
Now that you had confirms the information, you may extend it using vgextend
command. The command pattern is as follows:
$ lvextend <volume name> <disk device>
Example:
$ vgextend lvmvg01 /dev/sdg_crypt
That's all for expanding LVM volume.
