once upon a time we randomly needed to add two new separate lvm logical volumes to a server 1. verify which devices we will work with ::: {#cb1} sudo disk -l ::: We need to create physical volumes on both of these buggers: - /dev/sdb - /dev/sdc 2. create a physical volume on the 20G and 400G LUNs ::: {#cb2} sudo lvm pvcreate /dev/sdb sudo lvm pvcreate /dev/sdc ::: 3. create a volume group on the 20G and 400G physical volumes ::: {#cb3} sudo lvm vgcreate vg1 /dev/sdb sudo lvm vgcreate vg2 /dev/sdc ::: 4. create a logical volume on the new volume groups ::: {#cb4} sudo lvm lvcreate vg1 -l 100%VG --name app sudo lvm lvcreate vg2 -l 100%VG --name data ::: 5. format each logical volume with ext4 filesystem ::: {#cb5} sudo mkfs --type=ext4 /dev/mapper/vg1-app sudo mkfs --type=ext4 /dev/mapper/vg2-data ::: 6. create mount points ::: {#cb6} sudo mkdir /app sudo mkdir /data ::: 7. configure mount points in /etc/fstab ::: {#cb7} /dev/mapper/vg1-app /app ext4 errors=remount-ro 0 1 /dev/mapper/vg2-data /data ext4 errors=remount-ro 0 1 ::: 8. verify fstab ::: {#cb8} sudo mount -a ::: 9. verify new filesystems ::: {#cb9} df -hal ::: --- **Source:** [https://foxhop.net/f3d70a5f-2f95-11f1-8b49-e86a64d24d78/lvm-story](https://foxhop.net/f3d70a5f-2f95-11f1-8b49-e86a64d24d78/lvm-story) **Snapshot:** 2026-10-16T05:51:51Z **Generator:** Remarkbox `d747782`
