IncreasingSwapSize
The initial configuration of swap space is only 32MB. this prevents successful hibernation.
Steps to change the existing configuration to a larger swap are based on recipes as for example in http://geekpeek.net/resize-filesystem-fdisk-resize2fs/
- boot into the recovery image
- reduce /dev/sda3 in size to make enough room after it using resize2fs. For instance remove 7GB in sectors at the end to fit a 6GB swap. (resize2fs /dev/sda3 225G)
- change the partition size of /dev/sda3 by deleting and recreating it with a reduced length (for example original minus 6*1024*1024*2 sectors)
- delete the existing swap partition /dev/sda2
- create a new partition /dev/sda2 (type 0x82) starting after /dev/sda3 until the end of the device (old end of /dev/sda3)
- extend the filesystem on /dev/sda3 again to fill up to the full size (resize2fs /dev/sda3)
After this the partitions are out of order, but this has not been an issue so far. It may look like:
