Operating Systems Linux Red Hat Increase root partition in LVM Post 302524714 by verdepollo on Tuesday 24th of May 2011 09:44:08 AM

What's the output of vgdisplay and lvdisplay?

Usually the process is something like this:

Code:
pvcreate /dev/sda3
vgextend VolumeGroupName /dev/sda3
lvextend -L +16G /dev/VolumeGroupName/LogicalVolumeName /dev/sda3

And then you extend the filesystem:

Code:
ext2online /dev/VolumeGroupName/LogicalVolumeName

Also I'd suggest you have a working backup of your root partition in case something goes wrong.
