Unfortunately I'm not very familiar with writing driver code, and I'm painfully out of practice with writing code in general. For someone interested in looking, the source for the modified md driver is available from lime-technology that they use to implement these features. I don't know if I'm able to attach the files to this message, so I'll just tell you how to get them. Download from http://lime-technology.com/dnlds/ the unRAID Server install. I got version 4.2.4. I used 7zip (I'm in Windows at work) to open the archive and then open the bzroot image. The source files are in bzroot\[Content]\usr\src\linux-2.6.20\drivers\md\ . Hopefully that will be useful to someone. > Date: Wed, 28 May 2008 19:14:30 -0400 > From: davidsen@xxxxxxx > To: cgreen@xxxxxxxxxxxxxxxxx > CC: tony_germano@xxxxxxxxxxx; linux-raid@xxxxxxxxxxxxxxx > Subject: Re: Proposal: non-striping RAID4 > > Agree, you can't get that with current kernel, although I think the > parts are there to actually make it work.

Interesting summer project for someone. _________________________________________________________________ Give to a good cause with every e-mail.
