Role Name
=========
Role to manage LVM Groups/Logical Volumes. Can be used to create, extend or resize LVM.
Role to manage LVM Groups/Logical Volumes. Can be used to create, extend or resize LVM Groups and volumes.
Requirements
------------
Devices/disks to be part of the LVM setup must be identified prior to using this role. Ensure that you select the correct devices/disks.
##### Creating LVM
###### /dev/sda5
##### Extending LVM
###### Current disk /dev/sda5
###### New Disk /dev/sdb
