I've tried to resize my home partition using parted. Prior to it I had removed ext3 flags following some advices found on net. Resizing failed and I ended up with filesystem bigger than partition. Then I managed to enlarge the partition using fdisk but it didn't help. When I run fsck on it it prints:
fsck from util-linux-ng 2.16.2
e2fsck 1.41.9 (22-Aug-2009)
fsck.ext2: Group descriptors look bad... trying backup blocks...
fsck.ext2: Bad magic number in super-block when using the backup blocks
fsck.ext2: going back to original superblock
fsck.ext2: Device or resource busy while trying to open /dev/sda6
Filesystem mounted or opened exclusively by another program?
(Same message when fscking from live cd).
I had a backup of most important data and it was a new system, but there where some notes that I had made whilst setting my linux up and it would be nice to have it back.
