Troubleshooting

If pvgroup doesn't see new space, need to extend the physical partition: growpart
Then rescan the physical volume: pvscan
Then extend logical volume: lvextend
Finally Resize File System: resize2fs

sudo growpart /dev/sda 3
CHANGED: partition=3 start=2101248 old: size=417327104 end=419428352 new: size=1046474719 end=1048575967
