LVM version checking cat /etc/os-release lvm version 2. Scanning disks lvmdiskscan lvmdiskscan -l pvscan vgscan lvscan 3. Creating Physical Volumes pvcreate /dev/sdb /dev/sdc /dev/sdd /dev/sde lvmdiskscan -l pvs pvdisplay /dev/sdb 4. Creating Volume Groups vgcreate jae-vg /dev/sdb /dev/sdc vgcreate koo-vg /dev/sdd /dev/sde vgs vgdisplay jae-vg vgdisplay koo-vg pvs pvdisplay /dev/sdb 5. Creating Logical volumes (Stripe volume) lvcreate -i 2 -I 8 -n jae-lv -L 10G jae-vg lvs lvdisplay jae-vg/jae-lv pvs 5. Creating Logical volumes (Mirror volume) lvcreate -n koo-lv0 -m1 -L 5G koo-vg lvs lvdisplay koo-vg/koo-lv0 pvs 5. Creating Logical volumes (Linear volume) lvcreate -n koo-lv1 -L 15G koo-vg lvs lvdisplay koo-vg/koo-lv1 pvs 6. Creating the Filesystems mkfs.ext4 /dev/jae-vg/jae-lv mkfs.ext4 /dev/koo-vg/koo-lv0 mkfs.ext4 /dev/koo-vg/koo-lv1 df -h /dev/jae-vg/jae-lv df -h /dev/koo-vg/koo-lv0 df -h /dev/koo-vg/koo-lv1 7. Mounting the Filesystems mkdir -p /jaekoo/jae-lv /jaekoo/koo-lv0 /jaekoo/koo-lv1 mount /dev/jae-vg/jae-lv /jaekoo/jae-lv mount /dev/koo-vg/koo-lv0 /jaekoo/koo-lv0 mount /dev/koo-vg/koo-lv1 /jaekoo/koo-lv1 df -h vi /etc/fstab /dev/jae-vg/jae-lv /jaekoo/jae-lv ext4 defaults 0 2 /dev/koo-vg/koo-lv0 /jaekoo/koo-lv0 ext4 defaults 0 2 /dev/koo-vg/koo-lv1 /jaekoo/koo-lv1 ext4 defaults 0 2 7. Unmounting the Filesystems umount /jaekoo/jae-lv umount /jaekoo/koo-lv0 /jaekoo/koo-lv1 vi /etc/fstab 8. Deleting Logical volume lvremove -f jae-vg/jae-lv lvremove -f koo-vg/koo-lv0 lvremove -f koo-vg/koo-lv1 lvs pvs 9. Deleting Volume Groups vgreduce koo-vg /dev/sde vgs pvs vgremove koo-vg vgremove jae-vg vgs pvs 10. Deleting Physical Volumes pvremove /dev/sdb pvremove /dev/sdc pvremove /dev/sdd pvremove /dev/sde pvs lvmdiskscan
