I have added some RAM to my netbook. I'd like to save an option to hibernate my computer, so I have to increase my SWAP from 2GiB to 4GiB.

My /etc/fstab looks like this:

UUID=57b6e4ca-86f6-440d-8d45-2295a86a946b /               ext4    errors=remount-ro 0       1

/dev/mapper/sda6_crypt /home           ext4    defaults        0       2

/dev/mapper/sda5_crypt none            swap    sw              0       0

My /etc/crypttab looks like this:

sda5_crypt UUID=17ec5831-e49e-4eb0-aa63-05101038a85c none luks,swap

sda6_crypt UUID=2a01b2a0-e954-4a97-9202-6cdbc0152e73 none luks

Appreciate any help.
