http://ubuntuforums.org – Ok here is my predicament. I had a 2TB hard drive that had a 1.8TB ext4 partition at the beginning of the drive (/dev/sda2) and I had a LVM volume group inside an extended partition on the rest of the drive (/dev/sda5). I made the mistake of vgextend VolGroup /dev/sda5 and have lost access to my 1.8TB partition. I have done nothing else with this PC (not even rebooted). (Hardware)
