[Solved] Systemctl Hibernate Swap Header Not Found

calavoow · 2016-04-10 11:33:48

Hello Arch Forums,

I've recently installed Arch according to the wiki for a fully encrypted filesystem (https://wiki.archlinux.org/index.php/Dm … _with_LUKS) and followed the page to set up hibernation using a swapfile on an encrypted filesystem (https://wiki.archlinux.org/index.php/Dm … _swap_file). However, when I run `systemctl hibernate` the system momentarily looks to power down but starts up immediately after. I would like to be able to hibernate my laptop so that the data on it is encrypted when I close the lid to move around.

When I run `dmesg` I find the error Swap header not found:

#GRUB_SAVEDEFAULT="true"

Which I've written to `/boot/grub/grub.cfg`using `grub-mkconfig`.

Where `resume_offset` is decided by running according to the wiki

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

which outputs

2146304..

The output of `swapon -s` is

Filename				Type		Size	Used	Priority
/swapfile                              	file    	8388604	0	-1

All of which looks okay. I'm not sure if its necessary to have a swap that large, but my memory is also 8G so just to be sure I made my swapfile the same size.

Finally, my `mkinitcpio.conf` looks as follows:

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES=""

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect block filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev block filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev block mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev block lvm2 filesystems"
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block encrypt resume filesystems keyboard fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=""

This hopefully also correctly executes the resume hook only after system has been decrypted.

Any ideas on how to resolve or debug this issue and hibernate my laptop?

Can you provide us with the output from

$ cat /proc/cmdline

It will confirm the parameters are passed to the kernel correctly

calavoow · 2016-04-10 15:28:47

Of course, here:

$ cat /proc/cmdline
initrd=\initramfs-linux.img cryptdevice=UUID=fccddb3a-626e-48a8-b6e6-e824075e9c92:cryptroot root=/dev/mapper/cryptroot

The resume_offset setting isn't present in that output; so somehow that didn't work out

You were right so I dug deeper and solved the issue. It turns out it wasn't reading linux parameters from GRUB, because I use an UEFI boot with systemd-boot. Which for me is configured in `/boot/loader/entries/arch-encrypted.conf`. The following config succesfully hibernated and resumed:

title Arch Linux Encrypted
linux /vmlinuz-linux
initrd /initramfs-linux.img
options cryptdevice=UUID=fccddb3a-626e-48a8-b6e6-e824075e9c92:cryptroot root=/dev/mapper/cryptroot resume=/dev/mapper/cryptroot resume_offset=2146304 quiet
