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.

Update 09/16/2015 – I have published an updated article for this here: http://blog.allanglesit.com/2012/08/bash-automatically-mount-file-systems-on-volume-group-if-present/

In my laptop I have a solid state disk, and frankly I am way past addicted to solid state disks, but what you get in performance you lose in capacity. As such I have had to be creative with how I can have the capacity and the performance that I need. Lately the solution has been to have a spinning disk in the slot that would normally be occupied by my CD/DVD drive. However the problem with this, revealed itself to be that my Fedora install would actually fail to boot when it tried and failed to mount the file systems if this device was not present. So my first “solution” was to set noauto in the /etc/fstab for these secondary file systems. Which presented a new problem… I would forget to manually mount these devices before launching Virtualbox to start my VMs. So I decided that I would need to have an auto-mount script which would check for the volume group to be present and then if it was mount the file systems contained within the /etc/fstab which live on the volume group.
