Hi Everyone, First I want to say that dmraid was been a wonderful tool for use. We use it with many Sun X2100s, and other motherboards with great success. The only feature we really miss is an option like mdmonitor to notify us if there is a problem with an array. However, I have several identical Supermicro X7DBR-i+ (BIOS 2.0) motherboards that seem to have issues with dmraid. I'm not sure if it's a problem with the board, dmraid, or the combination. The motherboard provides with option for either an Intel or Adaptec code base. We had exceptional troubles (corruption, or drives just disappearing, normally unable to complete install) withe Intel code base and decided to try the Adaptec option instead. It appeared to work, but on closer inspection after install it's still not working right. With 1.0.0.rc13 the array appears to be recognized by dmraid, but never activated through the device mapper, instead the operating system was mounting the underlying physical device based on it's label. I noticed that it was using the ddf1 "driver" for the array and looking through the changelog and noticed that there was a fix for some ddf1/Adaptec problems in rc14 so I upgraded to that and rebuild initrd, etc. However, while I appear to be able to successfully manually start the array, it appears to not work within the sysinit/initrd default procedure. While "/sbin/dmraid.static -ay -i -p -t" grep, etc does return the array name eg: ddf1_Volume0 the later command to activates fails with a seg fault eg: /sbin/dmraid.static -ay -i -p "ddf1_Volume0". However without specifying an arrayname it appears to activate properly. It looks like the initrd was written for dmraid using the "-p" arrayname to utilize kpartx to create the partition device maps with the "p" deliniator. I would guess that if one could specify the partition deliniator then kpartx and the might not be needed? Any thoughts on how to debug this issue further? I can provide more details.
