[HowTo] Enable and configure hibernation with BTRFS

openminded · 14 February 2021 06:54

As far as I remember, swapfile should be created on a special subvolume with CoW disabled.

thomas85 · 8 July 2021 12:02

amazing!
thank you, it works!

I have been looking for weeks to get this working, see my previous ramblings about the topic here:

(I even wasted several hours to try to setup an Arch installation, but failed miserable )

thomas85 · 22 September 2021 16:09

If I understood it correctly, CoW can only be disabled globally for the whole btrfs file system or for single files as done by the command:
chattr +C ./swapfile

The nodatacow option is ignored for subvolume mounts, if other subvolumes of the same btrfs filesystem have been mounted before without it. (at least that’s what I read here: [SOLVED] BTRFS: nodatacow on subvolume / Newbie Corner / Arch Linux Forums )

The only thing missing is creating this file on a seperate subvolume, in order for things like Timeshift to work correctly. You do not want to include a huge swapfile in snapshots and backups.

Simply add btrfs subvolume create /@swap to the beginning of your script and replace /swapfile for /@swap/swapfile in your script should do it. I will try it out later.
This also corresponds with the Manjaro wiki. It is a requirement for compatibility:
Swap - Manjaro

Also, when you run this script after installing Manjaro and you had already selected “swapfile” during setup, the script deletes the existing swapfile first. All good, but should you not first do swapoff -a otherwise the file is probably locked/in use? Also, should you not first unmount the swapfile?

@megavolt your script misses a closing bracket on line 54.
Also, my /etc/fstab contains the following commented line:
# Created by a script\n/swapfile\tnone\tswap\tsw\t0\t0 nothing below this comment.
The script should have added:
/swapfile none swap sw 0 0
In my case:
/@swap/swapfile none swap sw 0 0

Hello @zilexa

I added a note so that it makes clear that you can edit the article at any time:

So if you think that a subvolume should be used, then feel free to change or add it there.

zilexa · 16 November 2021 09:31

@megavolt I updated & tested the script, works fine now (tested on Manjaro Gnome).

It will now first disable swap, backup fstab and remove any lines with “swap” in fstab before creating btrfs swap properly.

However, I do have 1 question: Why do you need to install pm-utils ?
It won’t install when you use the script because it conflicts with tlp. But after running the script (and verifying pm-utils is indeed not installed and tlp is still installed, hibernation works fine?

megavolt · 18 November 2021 18:41

TLP and pm-utils share some symlinks and therefore it conflicts, but I see that I actually use systemd on all systems… FS#38692 : TLP and pm-utils are now conflicts

I will comment it out and remove it after it is clearly verified

Hello, I followed a mix of this tutorial and the arch wiki to make swapfile working on my Manjaro Plasma system.
In particular I followed the arch wiki here and here (the first one links the second one, so read the steps carefully), creating the swapfile on a new dedicated and non-snapshotted subvolume (no compression, discard and autodefrag options).

In particular, on my old pc I had no problems using

filefrag -v /swapfile | awk '{ if($1=="0:"){print substr($4, 1, length($4)-2)} }'

I saw this arch wiki page: https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation_into_swap_file_on_Btrfs and I tried to compare the results of both ways and there were identical.

But I have to claim that with my new pc the filefrag command didn’t worked, like wrote in the arch wiki.
So, using the btrfs_map_physical.c method I was able to set up the hibernation correctly.

The part of this HowTo that I found very useful is:

megavolt:

Then add resume after filesystems with space between to the HOOKS= variable in /etc/mkinitcpio.conf like this:
HOOKS="base udev autodetect modconf block keyboard keymap filesystems resume"
Now we need to bypass the memory check because systemd does not support it on btrfs.

Edit the services with:
sudo systemctl edit systemd-logind.service
and
sudo systemctl edit systemd-hibernate.service
and add there:

Environment=SYSTEMD_BYPASS_HIBERNATION_MEMORY_CHECK=1

Thank you all for the collaborative effort!

@megavolt when installing the latest (stable, from homepage) Manjaro Gnome, your script no longer works. A swapfile is created and is ‘active’, but hibernation is impossible. Tested on an Intel Nuc gen8 and HP Spectre x360 14 (Intel). With both, your script worked when I installed Manjaro in November.

Now that I have done clean install and run it again it no longer works. The errror

apr 07 11:53:26 Idefix kernel: PM: Cannot find swap device, try swapon -a
apr 07 11:53:26 Idefix kernel: PM: Cannot get swap writer

My swapfile is mounted and working. free command shows swap does exist.

I have no clue how to solve this.
I whish the developers would add “Swapfile with hibernation” (in a subvolume, no need to snapshot the file) in Calamares for BTRFS, that would make it so much easier

Rulinux · 31 May 2022 07:52

@megavolt Does your instruction How to Enable and configure hibernation with BTRFS]([HowTo] Enable and configure hibernation with BTRFS) also work with LUKS-encryption?
What exactly has to be considered extra in case?

megavolt · 31 May 2022 08:14

Not sure, but according to the ArchWiki, the only thing what changes is that the resume parameter at grub must point to unlocked/mapped root partition (which contains the swapfile).

resume=/dev/mapper/root_device

I am actually not very interested in full encryption and therefore can only point to wiki articles.

PS: I reworked the steps a bit recently. If you stuck somewhere, see a mistake or have a suggestion, please note it here or edit the content. thanks

zilexa · 2 June 2022 07:32

Hey thanks for this, I was also going to spend some time fixing the old script that didn’t work.

I applied your steps to a clean install and found a few minor issues, like setting permissions to /swapfile, instead of /swap/swapfile. Mounting to /swap before creating /swap
Also, for some reason temporarily mounting using /dev/... didn’t work. I am used to doing everything via uuid anyway so that is how I solved it.
This way, only 1 variable is used since you use uuid already in fstab.

But the main issue I found (also in the old script):

echo -e "GRUB_CMDLINE_LINUX_DEFAULT+=\" resume=UUID=$swp_uuid resume_offset=$swp_offset \"" | sudo tee -a /etc/default/grub
Gives me:

GRUB_CMDLINE_LINUX_DEFAULT+=" resume=UUID=7d25c3b8-0c7b-4fd3-8de6-eb911909e71b resume_offset=5288750 "

This does not seem correct:

the “+”
the space before resume
the space after the offset number.

I removed the + and extra spaces, performed the rest of the steps and will reboot now

zilexa · 2 June 2022 08:15

Unfortunately, still doesn’t work for me.
I have re-checked all steps, I have my @swap subvolume, it is mounted (checked with mount) to /swap, it contains swapfile, I can see it is active via free command. Yet the error I get is:

Cannot find swap device, try swapon -a
Wtf? I don’t get it.

jun 02 10:12:03 Idefix gnome-shell[1031]: Removing a network device that was not added

EDIT:
OK I found more issues, fixed now:

sudo sed -i "s/ filesystems / filesystems resume /g" /etc/mkinitcpio.conf does not work because in the file, filesystems is the last attribute, there is no space after it, just ". This is on a clean install of Manjaro Gnome (installed yesterday with latest image from homepage).
(see response from freggel.doe below, not an issue) the file /etc/default/grub already has a line with GRUB_CMDLINE_LINUX_DEFAULT=, after following the steps, an additional one is added to the bottom, I manually added those attributes to the top one and removed the bottom one:
Looks like this now:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor udev.log_priority=3 resume=UUID=7d25c3b8-0c7b-4fd3-8de6-eb911909e71b resume_offset=5288750"

Then I performed the last action, to update initcpio + grub and reboot.
Still, same error! Does not work.

I then checked this command:

export swp_uuid=$(findmnt -no UUID -T /swap/swapfile) && echo $swp_uuid

It returns the same UUID as findmnt / -o UUID -n, which is the UUID of my root drive/btrfs root subvolume /dev/nvme0n1p2, the same UUID that is in /etc/fstab to mount ech subvolume… it is not a unique UUID for /swap or /swap/file.

This might be the issue?

I looked up the btrfs UUID of the @swap subvolume, replaced it in /etc/default/grub, again updates initcpio + grub and rebooted, still cannot hibernate, exact same error

freggel.doe · 2 June 2022 08:38

But it is, see

In the context where an assignment statement is assigning a value to a shell variable or array index (see Arrays), the ‘+=’ operator can be used to append to or add to the variable’s previous value.

Using witespace “around” strings to append is commonplace to not mess up any previous content.

zilexa · 2 June 2022 08:39

@freggel.doe thanks! I restored that command in the wiki. But I already fixed that file manually on my, still hibernation doesn’t work. Might have found the culprit, see my latest message above you. Not sure how to fix.

megavolt · 2 June 2022 13:20

Hello @zilexa

I will check/test the script again with the latest xfce minimal iso (that is the one which I use for testing in a vm).

I will update this post, when finished this weekend.

zilexa · 2 June 2022 17:10

Thanks @megavolt I do believe every command in the guide now works correctly.

Why I get this error is beyond me.

I have had this error on older systems since almost half a year now. No matter how many times I configure this, always end up with the same error.
Now that I tested your new version on a clean new install I’m convinced the issue is not isolated to my systems.

megavolt · 3 June 2022 08:34

Hello @zilexa,

I guess I have found the issue and it was my mistake. I forgot that I didn’t use filefrag on my setup

Normally it is a “setup and forget” configuration for me and well you know, I have forgotten it.

Thanks @zomberman for mentioning it. Sadly you did not edit the wiki post. I almost over read it.

zilexa · 4 June 2022 07:12

Thanks!
With the new & updated wiki, my script is now working again, copy pasted the wiki and also enabled a few related stuff, tested & verified:

manjaro-gnome-post-install/btrfs-hibernation.sh at main · zilexa/manjaro-gnome-post-install · GitHub

The script will:

Automatically perform the actions in this wiki, creating the root subvolume for swap, swap file and configuring hibernation.
Additionally, enable "suspend-then-hibernate", the most modern way of standby! suspend-then-hibernate will be the default suspend method for suspend, always hibernating 2 hours after suspend.
Power-off key will skip suspend, instead hibernate the system immediately.
(If a laptop) lid close will “suspend-then-hibernate”.

What is suspend-then-hibernate?
The system will go quickly into standby and wake up quickly if woken by the user within 2 hours. Otherwise, it will automatically wake up and hibernate (write to swap & shutdown completely), saving battery power and preventing you from losing data when battery dies.
When you wake the system after 2 hours, wake up can take slightly longer as it will wake up from hibernation.

Great guide. Very well written and helpful. However I want to put a HUGE WARNING.

Before “step 2” of the Hibernation enabling with (mkinitcpio -P etc). Check that /etc/mkinitcpio.conf looks ok.
If it looks like this:

MODULES=(btrfs)
BINARIES=(/usr/bin/btrfs)
FILES=()
HOOKS=(base udev autodetect keyboard keymap modconf block filesystems fsck)
HOOKS+=" resume "

Then it’s not ok and running mkinitcpio -P will print errors “ERROR: Hook 'base resume ’ cannot be found” and now your system is unable to boot… (so don’t do this or don’t reboot until you fix it).

Instead, edit it like this, moving the resume to it’s proper place:

MODULES=(btrfs)
BINARIES=(/usr/bin/btrfs)
FILES=()
HOOKS=(base udev autodetect keyboard keymap modconf block filesystems fsck resume)

Then you can continue with “step 2”, but I would really do it like this instead:

Backup grub.cfg sudo cp /boot/grub/grub.cfg /boot/grub/grub.cfg.bak
Run sudo grub-mkconfig -o /boot/grub/grub.cfg first. If you want, diff the new conf with the backup to see that the changes are applied.
Then you can run sudo mkinitcpio -P. If gives you errors it’s important to fix them. Revert your config changes and then run sudo mkinitcpio -P again until it works. Warnings are fine though (especially “Possibly missing firmware for module” which are common).
Reboot
