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 :)
Regards, - Jake
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 :) Richard

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, - Jake

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.
