Operation Process

To manage EVS disks using LVM, you need to first install LVM, create logical volumes, and then create and mount file systems on top of the logical volumes.

With LVM, a file system can be created on top of multiple EVS disks and can be easily resized as needed. This way, the file system size is no longer limited by the underlying disk capacity.

You can increase the file system size in either of the following ways:

• Extend the logical volume directly if the unallocated space in the volume group is sufficient.
• Extend the volume group and then logical volumes if the unallocated space in a volume group is insufficient.
