If you haven't completed the install, make the swap during the install when you configure the disks. If you've already finished the install, the Handbook has a section[0] describing methods for adding swap. > Is It recommended to configure swap area in both HDs ?? I don't see the point -- swap is where pages that don't fit in your real memory go. It's less optimal than real memory in terms of latency, but I don't see how two disks would make swap performance much better. > How large ?? I'd suggest 1-4G of swap depending on whether you need to read full dumps of the kernel/memory for debugging. If you don't, you'll probably be fine with a lesser amount of swap, unless you'll be running applications which will overload the memory.
