swap partition size regarding to kernel panic ?
 

Hello!
I last days i reading a lot information about creating software RAID 1 massives under linux, and in one document in russian ( looks it translate from english, but not contains any link to original) i found advice to create swap partition with minimum size of RAM *1.25, because, as they wrote, in such a kernel panic, for all ram amount must be entire on swap partition, because if not, can be data damage in next partition space on HDD.... ( it means, when encaounter a kernel panic situation, kernel puts all RAM contain to swap file / partition).
can anyone, who is close with "how kernel works in low level", comment this? it is a real thing, or myth?

Myth - absolute rubbish.
In a panic, the contents of memory are not (usually) written anywhere - all processing effectively just "stops". It is possible to configure things like kdump to write out dumps, but even that won't write over the current swap partition.

Ever since I've had systems with 1GB or more of RAM, I've stopped adding a swap partition and never had a problem yet. I don't know though if the fs one uses would make any difference, but I've been a firm believer (and it's paid off many, many times!) in reiserfs...just in case that happens to come up for any reason.

2 syg00: thanks for clarification.
2 irgunII: i found, even small swapspace enabled do system work better. after i installed slack14 32bit on my home desktop with 3 gb ram, i do with commented swap in fstab, but sometimes after a few hours work ( i use kde) it strangely lost network settings ( ip address). maybe its not chained, but after that i enable swap space, and computer looks like work a bit better. simply me own opinion...
