Creating and Extending Logical Volumes

While I do not frequently have the need to create or extend logical volumes, I find that every time I do I need to lookup the commands. To make it easier for myself and others, I have decided to put together the commands I frequently run.

UPDATE: Added some more information and broke it down into a two step process.

1. Disk

a. DisksĀ less than 2 TB

NOTE: You can join multiple disksĀ that are less than 2TB together instead of using a larger disk.

b. Disks greater than 2 TB

2. Volumes

a. Create volumes

b. Extend volumes

NOTE: I find that using -L with a size often fails and -l with extents works better. You can use vgdisplay to find out how many extents you have available to use.
