I want to increase the main partition size on Ubuntu 12.04.5 LTS server. I'm trying to follow this guy's tutorial.
At "Increasing the logical volume" step (I'm using sda2 instead of sda3):
root@Ubuntu:~# pvcreate /dev/sda2 Physical volume "/dev/sda2" successfully created root@Ubuntu:~# vgdisplay No volume groups found
So I'm stuck here. Next step is to extend the volume group, that you learn from vgdisplay command.
EDIT: Maybe I have to pvcreate /dev/sda1... according to this:
But sda1 is my / partition, so I get "device is busy".
EDIT: The output of df is:
/dev/sda1 16G 3.2G 12G 22% / udev 487M 4.0K 487M 1% /dev tmpfs 100M 220K 100M 1% /run none 5.0M 0 5.0M 0% /run/lock none 497M 0 497M 0% /run/shm
/dev/sda2 not visible here...
