Learning Linux : Lesson 20 Managing LVM

More videos like this online at http://www.theurbanpenguin.com . Welcome to this lesson in the learning Linux series. here we will take a look at managing logical volumes in Linux, or LVM2. Using static disk or partitions for file-systems is ok, however the issue will always be when you run out of disk space then you have to add a bigger disk and copy the original data across. Using LVM disks we just need to add extra disk space and extend the volumes. At the bottom of the LVM structure is the storage itself, this is marked as available to LVM with pvcreate. Then in the middle we have volume groups, these groups consume the storage from physical volumes. In the video we look at vgcreate, vgscan and vgextend. Then we present logical volumes to the file-system . LVs take space from the volume groups and we look at lvcreate , lcscan and lvextend. I hope this helps and is of use,
