To create a logical volume and mount it on Linux, you can follow these steps:

  1. Make sure you have the Logical Volume Manager (LVM) tool installed. If it is not installed, use the package manager for your Linux distribution to install the lvm2 package.
  2. Create a physical volume using the pvcreate command. For example, if you want to use /dev/sdb1 as the physical volume, you can run the following command:
  3. Create a physical volume on /dev/sdb1 using sudo.
  4. Use the vgcreate command to create a volume group, which is a logical collection of physical volumes. For example, to create a volume group named myvg and add the physical volume /dev/sdb1 that was just created to this volume group, you can run the following command:
  5. Create a volume group named myvg using the /dev/sdb1 device.
  6. Create a logical volume using the lvcreate command. A logical volume is a logical partition within a volume group. For example, to create a logical volume named “mylv” with a size of 10G, you can use the following command:
  7. Create a logical volume named “mylv” with a size of 10GB in the volume group “myvg” using the command “sudo lvcreate”.
  8. Run the mkfs command to create a file system on a logical volume. For example, if you want to create an EXT4 file system on a logical volume, you can run the following command:
  9. Create an ext4 file system on the logical volume named “mylv” in the volume group “myvg” using the command “sudo mkfs.ext4 /dev/myvg/mylv”.
  10. Create a directory to use as a mounting point. For example, to create a directory named /mnt/mylv as the mounting point, you can run the following command:
  11. Create a directory called “mylv” under the /mnt directory.
  12. To mount a logical volume onto a mount point using the “mount” command, for example, to mount the logical volume /dev/myvg/mylv onto the directory /mnt/mylv, you can use the following command:
  13. Mount the logical volume named mylv from the volume group myvg to the directory /mnt/mylv using sudo.

You have now successfully created a logical volume and mounted it to the designated directory. You can access and use the files in the logical volume at /mnt/mylv.
