How do you extend logical volume?

How do you extend logical volume?

In short, here are the steps to extend the size of your logical volume:

1. Create new partition on harddisk.
2. Add the partition you just created as a physical volume.
3. Add the new physical volume to the volume group.
4. Assign space from the volume group to the logical volume.
5. Resize the filesystem.

How do I extend physical volume in Linux?

Extend LVM manually

1. Extend the physical drive partition: sudo fdisk /dev/vda – Enter the fdisk tool to modify /dev/vda.
2. Modify (extend) the LVM: Tell LVM the physical partition size has changed: sudo pvresize /dev/vda1.
3. Resize the file system: sudo resize2fs /dev/COMPbase-vg/root.

Is it possible to increase the logical volume on fly?

This process is extremely easy to do with LVM as it can be done on the fly with no downtime needed, you can perform it on a mounted volume without interruption. In order to increase the size of a logical volume, the volume group that it is in must have free space available.

How do I extend XFS logical volume?

2. Extend the underlying device (lvextend, grow LUN, expand partition).

1. Identify the new disk and create a Physical Volume. # pvcreate /dev/sdc.
2. Extent the Volume Group vg_test using the new PV.
3. Verify the new size of the volume group.
4. Extend the logical volume to the desired size using the “lvresize” command.

What is a major advantage of using logical volume management?

The main advantages of LVM are increased abstraction, flexibility, and control. Logical volumes can have meaningful names like “databases” or “root-backup”. Volumes can be resized dynamically as space requirements change and migrated between physical devices within the pool on a running system or exported easily.

Why can’t XFS be shrunk?

The reason it hasn’t been done is that there is basically no demand for shrinking large filesystems. Storage is -cheap-, and in most environments data sets and capacity only grow.
