The kernel will automagically stripe all swap partitions given. Ie, if
you tell swap to use /dev/sda1 and dev/sdb1 it will, in effect, use the
equiv of raid 0 across them. Now, if you want to do something kinky like
raid 5, your at the point where you might as well just buy more memory
and forget about swap. :)
Sometimes I need up to 1G of swap, but that seldom occurs, so I'd like to
use that space as temporary and creating a swap file only when necessary.
I have a raid0 (striped file system) on which I'd like to build the swap
file.
Does any of you remember having seen such a discussion in the past? Does
anyone have references? Thanks.
