Hi @SmartManoj,

Your swapfile is already 4GB full and it would need to store the 8GB RAM additionally. This doesn’t work.

According to Power management/Suspend and hibernate - ArchWiki

About swap partition/file size

Even if your swap partition is smaller than RAM, you still have a big chance of hibernating successfully. See “image_size” in the kernel documentation for information on the image_size sysfs(5) pseudo-file.

You may either decrease the value of /sys/power/image_size to make the suspend image as small as possible (for small swap partitions), or increase it to possibly speed up the hibernation process. For systems with a large amount of RAM, smaller values may drastically increase the speed of resuming a hibernating system. systemd#systemd-tmpfiles - temporary files can be used to make this change persistent:

/etc/tmpfiles.d/hibernation_image_size.conf

#    Path                   Mode UID  GID  Age Argument
w    /sys/power/image_size  -    -    -    -   0

The suspend image cannot span multiple swap partitions and/or swap files. It must fully fit in one swap partition or one swap file.[1]
