Moby,
THANKS!!!!!! That fixed my problem! Yes I don't know why people insist
swap should be on raid 0 other that performance reasons but if your
disk goes belly up then yeah your totally screwed. Anyways I'm glad I
didn't have to go raid 0 in order to fix this problem and now it works
my 10.3, very sweet thank you very much :)

I can't say I insist that RAID 0 for swap is safer in case of
malfunction, only that performance is improved and of course you get
twice the space over raid 1 and with Linux's ability to mkswap in other
partitions in an emergency, either when you run short or if the array
poops, you aren't really as exposed as you might think, IMO. But,
either way, I'm glad you got it going and I'll remember the 'resume'
trick for the future...Thanks Moby... The way many of us divide up our
physical drives to make up multiple raid arrays, if my swap partition
were to fail, it is likely that I have also lost a drive, which has
compromised my other raid arrays, so I have a lot of work to do, and
worrying about loss of swap space is the least of my problems :) FWIW,
I have 3 G of RAM and I rarely use any swap on disk, so my exposure is
somewhat minimal I would expect. That and the general reliability of
disk drives now days and I figure I have at least a few weeks of
relatively uneventful computing due to hardware failure ahead....now,
10.3 GM is another story :)

Well the reason why I didn't make it raid 0 because if one of the
disks were to go bad then my whole raid would go down right? Can you
give me the steps on how to make my md1 device a raid 0 without
reformatting my whole system? I don't think I can stop md1 unless I
stop all the md devices above it right? (md2/3/4/5)
Thanks,

Hello,
I tried to setup a fresh install of 10.3 with 2 disks and I used YaST
to mirror all my partitions. I had originally my raid swap partitions
on an extended partition but that didn't work and I thought that was
the problem so instead now I put the raid partitions on primary
partitions, which still doesn't work.
Any suggestions would be appreciated because I'm completely stumped, I
can't figure out for the life of mine why my swap partition won't
work.
I think I would try making your swap partition RAID 0
I have MD0 /boot Raid1
MD1 swap Raid 0
MD2 / (root) Raid 1
MD3 /home Raid 5
and it works well with both 10.2 and 10.3. There is no advantage to
using raid1 with swap anyhow, you really don't need it to be backed up
or duplicated and it just slows the system down even if it did work.
Most welcome Jake and Richard.
Richard, my apologies if I sounded a bit harsh - just my frustration
showing on having fought the very same issue for too many hours today
before finding the fix. As for swap on RAID1 - well, raid'ing any disk
has pros and cons. The machine I was fighting the very same issue on
today is almost guaranteed to swap once it goes live, and I need to have
it able to run until I can get around to fixing it should a disk go bad
- hence the decision to put swap (and everything else) on RAID.
