Auto suspend after some time of hard drive inactivity

[Menhir]

Hi,

I am using Gentoo on my builded NAS. It means I have no GUI, just simple gentoo.
I want to fully hibernate after some time of inactivity. Is there any posibility to do it?

I instaled laptop-mode, and have fucntioning pm-utils with possibility to hibernate to disk a then resume manualy.
I also setup wake on lan. I just want my NAS going to deep sleep if we not use it for a while and then wake it on lan.

Can you help me?

Thanks,

Hello,

first the Linux kernel must know where to copy the memory contain on the hard disk and where to resume. It's in a swap partition. The swap partition must be enough big to contain all the memory size.Than the kernel parameter resume=/dev/sda1, or anywhere else the swap partition is, must be pass at the boot time before to hibernate and at the resume time. So the kernel know where to hibernate and resume. It can be set in the kernel image too.

When I hibernate, I do it through a command line

Hello,

I managed to setup kernel, grub2 with kernel resume parametrs, etc. It's working and resuming like a charm.
What I do not have is enough experience to make script you mentioned. Any help?

Thanks a lot
