I've got a MacBook Pro (late 2011). I just bought a 1TB HDD to replace the original 500GB. My plan was to partition the 1TB in half and let one side be Ubuntu and the other OS X (until I can reasonable get rid of OS X. I need it for work).
Right now I have Ubuntu 12.10 installed on the 1TB and it's fine, but it's taking up all of the drive. It automatically set the partition that way. I made sure to check the LVM box. Easy to resize, they said. Right. Here's what I've got right now, as seen from booting up on a live CD or USB:
The partition is locked. It's not mounted though. Yet for the life of me I can't figure out how to resize it. It makes me wonder why I bothered with the LVM in the first place instead of just installing on FAT32. In fact the real reason it's this way is that I just let it do the auto install, and was never given an option for other partition setups. I did this because I wanted to make sure the EFI partition was set up right. I've had problems with that on past computers.
I have a few questions, but only a few need to be answered to solve this for me. I'm less concerned with the intellectual pursuit at this point than I am in just getting it working.
Why can't I resize this? Why is it locked? More importantly, how do I fix this? Google returns answers that don't work for one reason or another.
Should I go back and reinstall but do it all manually and set it up as 2 partitions? If so, do I need to create a EFI and swap partition in the process, or is EFI taken care of automatically?
I'm coming back to linux after years away, so I'm quite rusty. Any help will be greatly appreciated.
edit: the following is from the terminal
ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda3 e2fsck 1.42.5 (29-Jul-2012) /dev/sda3 is in use. e2fsck: Cannot continue, aborting. ubuntu@ubuntu:~$ umount /dev/sda3 umount: /dev/sda3 is not mounted (according to mtab)
So it's in use but yet it's not mounted?
