[SOLVED] Can't hibernate Not enough swap space for hibernate errror

zakrush · 2023-05-02 11:31:19

Hello.
I can't to setup hibernation.

I have brtfs filesystem.

I get this error:

systemctl hibernate
Call to Hibernate failed: Not enough swap space for hibernation

I increase swap file to 34 GB from 24Gb but it don't help me.

Some my debug outputs:
free -h

               total        used        free      shared  buff/cache   available

Somebody can help me?

seth · 2023-05-04 06:20:48

Don't do that

Did you use the btrfs-progs to create and reference the swap file?

Ok.
Thanks, but I didn't have any idea what I can enable hibernation.
Yes. I all did as describe instructions.

this is my history of commands:

 sudo btrfs filesystem mkswapfile --size 34G /swapfile
 sudo swapon /swapfile
 sudo ./btrfs_map_physical /swapfile

the result of ./btrfs_map_physical /swapfile

Yes. I all did as describe instructions.

No, you did obviously not.

What is "./btrfs_map_physical", why does it produce completely unaligned output and where does "resume_offset=3763994" come from?

I get it from old version of wiki
see here
https://wiki.archlinux.org/index.php?ti … did=758420

where does "resume_offset=3763994"

It is first phisical offset devided to PAGESIZE

The
btrfs inspect-internal map-swapfile -r /swapfile
has the same result:

sudo  btrfs inspect-internal map-swapfile -r /swapfile
3763994

Did you create the swap file on a non-snapshotted subvolume like https://wiki.archlinux.org/title/Btrfs#Swap_file instructs?

Note:
For a stacked block device such as an encrypted container (LUKS), RAID or LVM, the resume parameter must point to the unlocked/mapped device that contains the file system with the swap file.

I all did as describe instruction. I create snapshot file on root subvolume.
It's

rootflags=subvol=@

As I understand I'm using LUCS:

cryptsetup -y -v luksFormat /dev/nvme0n1p5

How should to be looks my loader file on start topic message?

Here is my hooks in /etc/mkinitcpio.conf

HOOKS=(base udev resume autodetect modconf encrypt keyboard keymap consolefont block filesystems fsck)

~~Looking at your posted fstab, the resume= parameter looks correct.~~ A lot of people would likely use the same device specifier for both root= and resume=, but there's nothing wrong with using different ones as long as they resolve to the same block device.

Post the output of:

$ findmnt -no MAJ:MIN -T /swapfile
$ grep . /sys/power/resume*

There is output

findmnt -no MAJ:MIN -T /swapfile
  0:25

sudo grep ./sys/power/resume*
zsh: no matches found: ./sys/power/resume*

seth · 2023-05-10 06:10:49

sudo grep ./sys/power/resume*

grep . /sys/power/resume*

zakrush · 2023-05-10 13:05:38

So, sorry. I didn't see

findmnt -no MAJ:MIN -T /swapfile
  0:25

grep . /sys/power/resume*
/sys/power/resume:259:5
/sys/power/resume_offset:3763994

The resume= parameter in /boot/loader/entries/arch.conf is wrong.
I could have sworn the UUID in the resume= parameter matched with the "/" UUID in fstab when I first looked at it. I guess I can't read, shame on me.

What is wrong?
I tried to reinstall swapfile. Then I set up HOOK resume between filesystems and fsck as describe arch wiki. It didn't help me.

setup resume=/swapfile in bootloader also didn't help. I get /swapfile not found error on boot

zakrush · 2023-05-10 15:18:11

I understand.
nl6720 thank you very much. I'm see error. It was incorrect UUID in bootloader.
the command

findmnt -no UUID -T /swapfile

helped me to see it.
