Thanks for the reply. Should I be using a different version/release that would work better for RAID? If so, pls let me know. As far as your info requests, see below.
thanks.

OK, so RAID support is in the kernel and you've got the required modules loaded. What about your IDE drive? IIRC, you arn't using one of the kernels with IDE built-in, and it doesn't look like you're loading any IDE modules based on the above.
Can you access the low-level /dev/hdX devices that make up your RAID?
What does "fdisk -l /dev/hdc" and "fdisk -l /dev/hdd" show?
Are you *REALLY* trying to build a RAID5 device with two partitions on the same drive (/dev/hdd1 & /dev/hdd2 in your example raidtab, which go along with /dev/hdc1)? If so, I'm not sure that will work, and it wouldn't be recommended in any case...
# fdisk -l /dev/hdc
Disk /dev/hdc: 16 heads, 63 sectors, 8374 cylinders Units = cylinders of 1008 * 512 bytes
Device Boot Start End Blocks Id System /dev/hdc1 1 6242 3145936+ 83 Linux native
toaster: -root- # fdisk -l /dev/hdd
Disk /dev/hdd: 255 heads, 63 sectors, 977 cylinders Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System /dev/hdd1 1 392 3148708+ 83 Linux native /dev/hdd2 393 784 3148740 83 Linux native
As far as my raid5 device, I just want to make sure I can get the raid5 working before I buy a 3rd drive. My test set is 1 4gb drive (hdc) and an 8gb drive (hdb). I created 3 partitions each +3072M on the two devices and am trying to build the raid5 test. I also tried to do this with just doing raid1 on /dev/hdc1 and /dev/hdd1 and got the same error on the same command.
OK, you've got raid support in the kernel, and IDE support is working.
There's not a lot else that needs to be there for RAID to work. Did you remember to make the raid devices (ie: does /dev/md0 exist)?
<excerpt http://lrp.steinkuehler.net/Documentation/LRPHardDiskHOWTO.txt> Check to make sure the /dev directory contains all the devices you need for your hardware. You may also need to update /var/lib/lrpkg/root.dev.mk to create additional device nodes. I added the following lines on my system to support the newly added RAID functionality:
# RAID Devices makedevs md b 9 0 0 15 >null 2>&1 </excerpt>
What a bonehead! I totally missed that -- then again, I really don't understand what the command is/means so I'm not sure "missed" is the right word. :-) My ls -l /dev/md* returns no rows so there's the problem. Once I did this, I was able to run my mkraid, mke2fs and mount.
Thanks, Charles. You are the Man!
Actually - Thanks to all of you LEAF developers/contributors. I started using LRP w/the first version of eigerstein, and used to follow the list back before the big fallout with lrp. The names are remember from years ago: Charles -- I never did catch you on Robot Wars :-( ; Jack Coates and MonkeyNoodle for dinner, Tom Eastep, Ray Olszewski, Jeff Newmiller, Mike Noyes, George Metz, Matt Schalit, and even Dave Cinege inspired people to participate. I know I answered a few questions when I could, but alas, I'm not a developer, so I cannot contribute at the level I'd like to. I have been amazed at your dedication to the betterment of the community and appreciated when those of you who did took a stand to keep LRP pure and out of politics. I've watched the development of all the branches and saw new names take on leadership roles (David Douthitt, Jacques Nilo, Eric Wolzak, and so many others)...I very much appreciate that all of you take time out of your lives to develop this product and to teach us how to use it.
Thanks. mike.
PS -- I know I probably messed up my little trip down "Name Memory Lane" in that some people probably got involved before others, etc -- it's just how I remember things (or my email does) ;-) That being said, please know that any and all mentors on this list, regardless of when they started contributing, have my utmost thanks.
