Suspend2 - Change Suspend File Size
This is another one of my posts that's more for my notes than anything else. I
recently (as in today) got more memory for my laptop taking it from 256MB to
512MB. Since I'm using
Suspend2 to suspend to disk and am using the suspend file
vs the swap partition I had to increase the files size. The original one was
only 300MB, not enough to hold my physical RAM if it was full. So, I went to
the Suspend2 website and found out that the instructions for creating a suspend
file are not easy to find. Eventually I found the answer buried on a
Gentoo
Wiki.
The steps were as follows:
- Delete my old suspend file.
- Edit my hibernate.conf file by changing the
FilewriterLocation
line. The last number on the line is the size of the file to be created in MB.
I just made it a number larger than my physical RAM.
- As root run
hibernate --no-suspend which will create the file
and then tell what "resume2" line to put in your bootloader. If using LILO
don't forget to run lilo before rebooting.
That's it. Try a suspend and resume to see what happens. But make sure to get
it right the first time and have a good backup because resuming from a bad
suspend file has the potential to ruin your file system.
