When you run swapon - are you specifying the partition or just using the
- -a option? Ubuntu uses UUID in the /etc/fstab file, not /dev mount
points, and the UUID of the swap partition changed when you sic'ed
gparted on it.
Use vol_id or something like it to figure out the new swap partition
uuid, or just replace the uuid with the /dev path if you prefer.
Hope that helps,
