How to set swap in /etc/initramfs-tools/conf.d/resume if I have two swap partitons?

  • 772

I have two swap partitions in fstab :

    /dev/sda8    none            swap    sw,pri=1           0       0
    /dev/sdb8    none            swap    sw,pri=1           0       0

How to set swap in /etc/initramfs-tools/conf.d/resume file?

According to SwapFaq this will not work for 12.04:

INFO: This will not work for 12.04, resume from hibernate work differently in 12.04.

How to do it in Ubuntu 12.04?

  1. Check UUID

     sudo blkid

    Then

     sudo gedit /etc/default/grub

    to pull up the boot loader configuration. Look for the line GRUB_CMDLINE_LINUX_DEFAULT="" and using your UUID add:

    resume=UUID=41e86209-3802-424b-9a9d-d7683142dab7

    That means change this

       GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

    to this

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=41e86209-3802-424b-9a9d-d7683142dab7"

    save then edit:

    gksu gedit /etc/initramfs-tools/conf.d/resume

    and make sure its contents are

    RESUME=UUID=41e86209-3802-424b-9a9d-d7683142dab7

    (with your UUID of course in place of mine). Save the file!

     sudo update-grub
 sudo update-initramfs -u -k all

    Reboot!

    Edit: Technically only one of the two methods needs to be used, the kernel parameter in the grub file will take precedence over the initramfs resume config file

  2. (18.04) You can also edit /etc/initramfs-tools/conf.d/resume and change RESUME=UUID=$uuid to the output of blkid /dev/raidN (whatever block device your 2 swap devices are RAID'd as)
