I attempted to install grml automatically with an XFS file system.
Then, I installed grub, like this.
grub
root (hd0,1)
setup (hd0)
Then,
rebooted.
Then, I did:
echo disk >/sys/power/state
The box hibernated.
Then after about 3 minutes (note that I did not as yet try cutting all power) I turned it back on, and it resumed.
So then, I performed a second test.
I hibernated it again. But this time, (I shut off the power) (and it should have, retained the information and resumed anyways) but, it didn't.
In fact, the machine did not eaven boot up. Took me thousands of hard-forceful shut-downs and more, before I could get the computer working properly again.
Note:This all occured under an XFS file sytem.
So, I've decided not to use that one.
Mikap:
What file system do you use yourself, and, what file systems have you tested?
I want someone (if this has never been done) to test this out by hibernating a system with all the file systems GRML supports, and in every test shut off all power for about 5 minutes, turn on all power, turn on the computer, and see if it resumes.
Any tests, or assistance with this would be greatful!
Regards,
Keith
