Steps I have followed:

  1. Allocated free space from windows' C drive
  2. Booted from Ubuntu live USB
  3. Launched GParted
  4. Turned swap off
  5. Moved my root partition ext4[/dev/sda8] to the left of unallocated space
  6. Right click on ext4[/dev/sda8] - Check and repair filesystem ext4[/dev/sda8]
  7. Check ext4[/dev/sda8] successful
  8. Resize/Move ext4[/dev/sda8] to 48.23 GB - Apply
  9. ERROR!

What I have found:

  1. Bad Superblock Problem?
  2. Logical Partition table problem?

Please Help!

Apparently I was able to resize the root "/" partition while my OS was running and "/" was mounted.

Root file system /dev/sda8 extended to 48.83 GB: http://imgur.com/lINIUwn

Contrary to what I read everywhere on GParted official docs and forums, it is possible. I have restarted my system and verified it using disk-usage-analyser & gnome-disk utility.

Anyone knows how was this was possible? I'm willing to share further details.
