PM: Hibernation image not present or could not be loaded

Question

After hibernating with systemctl hibernate, the system boots normally as if it had been shutdown. I have the resume parameter in the kernel line and the resume hook in mkinitcpio.conf

These are the relevant kernel messages:

$ dmesg | grep -i swap
[    0.000000] Command line: initrd=\initramfs-linux.img root=/dev/sda2 rw resume=/dev/sda4
[    0.000000] Kernel command line: initrd=\initramfs-linux.img root=/dev/sda2 rw resume=/dev/sda4
[    0.350295] PM: Checking hibernation image partition /dev/sda4
[    8.776686] Adding 8191996k swap on /dev/sda4.  Priority:-1 extents:1 across:8191996k FS
$ dmesg | grep -i hibern
[    0.350295] PM: Checking hibernation image partition /dev/sda4
[    0.350301] PM: Hibernation image not present or could not be loaded.

So the only remaining possibility is that systemctl didn't write to disk. In fact, when I run the command, the screen first goes blank for a couple of seconds, then I can see my terminal again, and finally it shutdowns itself.

I read that pm-utils do not work very well with systemd, so I wouldn't want to switch to those. Any suggestions?

Thanks!

Solution

To elaborate @AdrianRatnapala's comment, you have to:

1. Find uuid of your swap partition. Suppose the partition is sdb3, then

   $ ls -l /dev/disk/by-uuid/ | grep sdb3
   lrwxrwxrwx 1 root root 10 окт.   9 08:59 1dd7e123-1f82-45f0-a202-0ff3ea6f081a -> ../../sdb3
   

2. Open /etc/default/grub, and find the line starting with GRUB_CMDLINE_LINUX_DEFAULT=". Add there between the quotes resume=/dev/disk/by-uuid/your-swap-uuid. As an example:

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=/dev/disk/by-uuid/1dd7e123-1f82-45f0-a202-0ff3ea6f081a"
   

3. Run as a root update-grub
4. A reboot is needed to use the new kernel command-line.

@AdrianRatnapala: Thanks for the help! I'll try your solution.

I have the same problem. Could you please share your solution here?

@abforce Following Adrian's solution worked for me. Replace normal paths with UUIDs in the kernel options.

[rubik]

I don't use Grub but the essence of the procedure is the same!

UUID of my swap changes every reboot so this doesn't work :(

[Hi-Angel]

@Petr this is weird… UUID should only change upon reformatting. I found alike bug-report though, but this is dated by 2008 year. Okay, just for the safe case try sudo mkswap </dev/partition-name>, then check its UUID with sudo blkid </dev/partition-name>. If it still would change upon reboot, I'd suggest you to ask a question at unix.stackexchange.com

[Hi-Angel]

@Petr ah, another thing to try before asking — you could manually set UUID of swap with sudo swaplabel -U <NEW-UUID> </dev/partition-name>. You could generate new UUID with uuidgen utility.

I think it's easier and safer to get the UUID with blkid. ls -l /dev/disk/by-uuid/ won't give you a useful output if you are using lvm.

grub-mkconfig -o /boot/grub/grub.cfg in Arch Linux. :)

Did not work for me still getting Jan 6 15:34:55 hostName kernel: [ 2.111487] PM: Checking hibernation image partition 86cfa90d-b28e-4915-8856-47750aac8903 Jan 6 15:34:55 hostName kernel: [ 2.165479] PM: Hibernation image not present or could not be loaded.

This answer provides some additional useful information that could be appended to the accepted answer. In particular, the need to reboot in order to use the new kernel command-line is obvious to experienced Linux users, but might trip up new users.
