Linux 101 : LVM, Physical Volumes - PV -, Volume Groups - VG - and Logical Volumes - LV -
We start by creating two Linux partition on our disk "/dev/sdb" as below:
We have our two partitions "/dev/sdb1" and "/dev/sdb2".
Physical volumes:
We can then check if they were created using the below command:
Volume groups:
We could check our volume group using the below command:
Logical volumes:
We can check our logical volume using the below command:
After creating our logical volume, we can create an "ext4" filesystem on it, to make it usable:
We then mount our volume on the directory "volume-mountpoint":
To survive a reboot, we would have to add our newly created volume in the "/etc/fstab" file:
We have our two partitions "/dev/sdb1" and "/dev/sdb2".
Physical volumes:
We create the physical volumes using the below command:
We can then check if they were created using the below command:
Volume groups:
We create the volume group using the two partitions:
We could check our volume group using the below command:
Logical volumes:
Then, we create a logical volumes of 500 MB named "volume-1" from our volume group:
We can check our logical volume using the below command:
After creating our logical volume, we can create an "ext4" filesystem on it, to make it usable:
We then mount our volume on the directory "volume-mountpoint":
To survive a reboot, we would have to add our newly created volume in the "/etc/fstab" file:
