[SOLVED] Hibernation with swap file

Hi,

first of all I followed the instructions from the wiki [1] but it's not working for me.

I identified the UUID of the partition containing the swap file

$ findmnt -no UUID -T /swapfile
---------
51557bdf-b990-4a05-bf4f-4d2626f47457

and the file offset

$ sudo filefrag -v /swapfile | head -n 10
---------
Filesystem type is: ef53
File size of /swapfile is 12884901888 (3145728 blocks of 4096 bytes)
 ext:     logical_offset:        physical_offset: length:   expected: flags:
   0:        0..       0:   18286592..  18286592:      1:            
   1:        1..    2047:   18286593..  18288639:   2047:             unwritten
   2:     2048..    6143:    3717120..   3721215:   4096:   18288640: unwritten
   3:     6144..    8191:    2793472..   2795519:   2048:    3721216: unwritten
   4:     8192..   12287:    2766848..   2770943:   4096:    2795520: unwritten
   5:    12288..   14335:    2775040..   2777087:   2048:    2770944: unwritten
   6:    14336..   16383:    1701888..   1703935:   2048:    2777088: unwritten

Which resulted in the following configuration

$ cat /etc/mkinitcpio.conf | grep ^HOOKS
---------
HOOKS=(base udev autodetect microcode modconf kms keyboard keymap consolefont block filesystems resume=UUID=51557bdf-b990-4a05-bf4f-4d2626f47457 resume_offset=18286592 fsck)

But building the initramfs image results in an error

$ sudo mkinitcpio -p linux
---------
...
==> ERROR: Hook 'resume=UUID=51557bdf-b990-4a05-bf4f-4d2626f47457' cannot be found
==> ERROR: Hook 'resume_offset=18286592' cannot be found
...

Did I overlooked something?

Re: [SOLVED] Hibernation with swap file

The UUIDs should be applied as a kernel parameter. They do not belong in the HOOKS array.
