On this tutorial I will show you how to create a Logical Volume using several disks. LVM (Logical Volume Management) is a powerful way to manage multiple disks under Linux. We can use any number of disks as on big disks. The system will see those disks as single disk. For more information you may want to read more about LVM.
Steps to create Logical Volume on Manjaro Linux
Step 1. Create Physical Volume
Step 2. Create Volume Group
Step 3. Create Logical Volume
Step 2. Create Volume Group
Step 3. Create Logical Volume
Step 1. Create Physical Volume
Physical volume can consist of many hard disks or partitions. We can add or remove disks from the physical volume. To create a new physical volume you will need one or more hard disks connected to Manjaro. Check the disk using fdisk -l or lsblk command.lsblkOutput
pvcreate /dev/sdb /dev/sdcOutput
Verify the new Physical Volume
pvdisplayOutput:
pvsOutput:
Step 2. Create Volume Group
Now we can create a new volume group. Volume group contains one or more physical volume. For example, we will create a new volume group called VGTest. I will add /dev/sdb to this VGTest.vgcreate VGTest /dev/sdbOutput
vgsOutput
vgdisplayOutput
In some cases we need to extend or increase the size of a volume group by adding more physical volumes. Here I will extend my previously created VGTest with /dev/sdc. We use vgextend command as follow.
vgextend VGTest /dev/sdcOutput
vgsOutput
Step 3. Create Logical Volume
Now we can start to create a new Logical volume. For example, I want to create a logical volume with 7 GB in size. I would use the following command:lvcreate -L 7G -n project VGTestThe command will create a new logical volume called project inside VGTest Volume Group with 7 GB in size. You can adjust the parameter to meet your own needs.
After created a new logical volume, we can then mount and format this logical volume.
