Gérer le swap
1. Via partition
Make a suitable partition with : gparted or cfdisk (or fdisk)
Format the new partition : # mkswap /dev/sdx1
Add the new swap partition to : /etc/fstab.
/dev/sdx1 swap swap defaults 0 0Run # swapon -a to activate the new swap.
2. Via file
Create the file : # dd if=/dev/zero of=/swap bs=1M count=1000 [1] (this creates 1Go empty file).
Give secure rights : # chmod 0600 /swap
Format the swap file : # mkswap /swap
Add the new swap partition to : /etc/fstab.
/swap swap swap defaults 0 0Run # swapon -a to activate the new swap.
3. Deactivate swap
# swapoff -a4. Add fstab options to allow the machine to hibernate
As per tok0z advice :
Add the resume=swap-device parameter in your fstab swap definition to allow the machine to hibernate.
And resume_offset=<swap_file_offset> if you use a swap file (instead of swap partition),
where <swap_file_offset> can be obtain via filefrag -v swap_file as explained on Arch wiki.
