Where is that image allocated? On the disk? There is still 65 GB of
space, so 16 GB of memory should fit? Could the error message be
improved, so users know more details to fix it?
Kind regards,
Paul

In swap. See docs.

Dear Pavel,
Thank you very much.

Thank you. Unfortunately, I am not seeing my case described in
`Documentation/power/`. Only:

I have 16 GB RAM and 8 GB swap partition.
$ LANG= free
total used free shared
buff/cache available
Mem: 13828768 9760192 3115932 5383256
6681400 4068576
Swap: 8387904 1531820 6856084
Shouldn’t user space (systemd or GNOME?) then know beforehand if
hibernate is possible? Is there a script for users to check, if
hibernation would be possible?
Kind regards,
Paul
