Linux-LVM: Resize Partition to Grow LVM Volume Group

Mon, 20 Aug 2012 00:00:00 +0000

Logical Volume Manager makes the dynamic expansion of file systems dead stupid simple. However there is a weakness, if you are using a partitioned file system as your Physical Volume (PV) then you will end up needing to expand the file system if you ever need to grow the actual storage. This can be avoided by using the actual physical device /dev/sda as the PV, however if this is the same volume where your /boot partition lives then you will have no choice but to partition it out since /boot cannot reside on a Logical Volume (LV). The other way you can avoid this is by simply creating a second partition on the same disk and adding it as a new PV to the existing Volume Group (VG). This is preferable as there is far less room for error than in this procedure, but I personally find that method a little more confusing to inherit then a straight forward single partition made an LV.
