Hmm? Since when does swapping work on raid-1? How about
swap running on raid then, if it works at all, is not actually
protecting you. the swap code in the kern is capable of doing
striping automatically if you have two swap partitions.
Yes it does. If one of two swap partitions goes down on non-raid
drives, the kernel locks up and you loose
Hi again,
I have done a small test with a raid-1 swap partition. I have filled up
memory so that the system swaps
to the raid swap partition with a little test program and the system
worked, top shows 800M of swap used
and still going. Does this tell me that it will always work? Or are there

Why do you want to swap onto raid?
Creating ordinary swap partitions with equal priority on
several drives will achieve the same speedup as far as I know,
as the kernel will spread swapping across all the swap partitions.
This achieves the same speedup as raid-0

AFAIK, the swap code uses raw file blocks on disk, rather than passing
through to vfs, cause you dont want to cache swap accesses, think
about it :)
Sort of correct. It does bypass most of the VFS, but it does use the
standard

Swapping to a file should work, but if I remember correctly you get
horrible performance.
Swap-file performance on 2.2 kernels is _much_ better.

It wasn't a month ago that this was not possible because it needed to
allocate memory for the raid and couldn't because it needed to swap to
do it? Was I imagining this or have you guys been working too

Can this be done? I have a machine that I may want to later expend using
linear mode expansion, but right now I on;y have one slice I'd like to
use. Can linear mode be initiated with only one drive at the present
time?
Thanks
