Extend size of LVM volume
1. Create a new partition
2. Create a Physical Volume (PV):
lvm pvcreate /dev/[new partition]
3. Add the new PV to the volume group (VG) you're extending:
lvm vgextend [vol_group] /dev/[new partition]
4. Extend the Logical Volume (LV) with the extended VG
lvm vgdisplay [vol_group]
lvm lvextend /dev/[vol_group]/[logical_volume]
5. Increase the size of the filesystem
resize2fs /dev/[vol_group]/[logical_volume]
6. Check the extended filesystem
e2fsck /dev/[vol_group]/[logical_volume]
7. Remount the filesystem
mount -o remount /dev/[vol_group]/[logical_volume]
