[opensuse] suspend to disk and size of swap partition
Hi there, in order to use suspend to disk one has to set a swap partition with the "resume=" option in the bootloader. Okay. But, if I have e.g. 2 GB of RAM I should have 2 GB swap space for suspend to disk. Now I have two seperate swap paritions, each 1 GB, in sum it is enough, but with "resum=" you can name only one partition. So, my question is, is "suspend to disk" intelligent enough to use ALL available swap partitions, though there is only one resume=/dev/hdc5 specified in GRUB ? /dev/hdc5 is only 1GB swap, but I have more swap space, does STD recognize them automagically? tia Malte -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

In the past, no. It would even refuse to suspend if you had two swaps defined. now I have two, and it works, but I don't know if it uses one for hibernation or both; I guess it ignores the second for the image, but it uses both for frozen apps. You can set up both, and set "resume" to one of them, and try. I believe it will refuse to go ahead if there is insuficient space. - -- Cheers, Carlos E.

This is exactly what I did, set up all swap partitions (actually 3, each 1 GB) and specified only 1 with resume= So far it works fine, hibernated correctly and woke up correctly. I hope hibernation will detect and complain automatically if there's not enough swap space...
