2. Step 2 – Find out information about new disk.
3. Step 3 – Create physical volumes (pv) on new disk named /dev/vdb.
4. Step 4 – Add newly created pv named /dev/vdb to an existing lv.

How do you add physical volume to an existing volume group?

To add additional physical volumes to an existing volume group, use the vgextend command. The vgextend command increases a volume group’s capacity by adding one or more free physical volumes. The following command adds the physical volume /dev/sdf1 to the volume group vg1 .

How use Pvmove command in Linux?

pvmove moves the allocated physical extents (PEs) on a source PV to one or more destination PVs. You can optionally specify a source LV in which case only extents used by that LV will be moved to free (or specified) extents on the destination PV.

How do I merge two logical volumes in Linux?

Follow the steps below :

1. Umount the mount points under both the VGs. # umount /data01 # umount /u02.
2. Deactivate the volume group we want to remove and merge with another VG. In our case it is vg02.
3. Merge the volume groups.
4. Activate the Logical volumes merged from vg02.

What is LVM volume group?

A volume group ( VG ) is the central unit of the Logical Volume Manager (LVM) architecture. It is what we create when we combine multiple physical volumes to create a single storage structure, equal to the storage capacity of the combined physical devices.

What is Pvmove?

Description. pvmove allows you to move the allocated physical extents (PEs) on SourcePhysicalVolume to one or more other physical volumes (PVs). You can optionally specify a source LogicalVolume in which case only extents used by that LV will be moved to free (or specified) extents on DestinationPhysicalVolume(s).
