Dear all, As you may know, many Intel motherboards ship with a BIOS fakeraid (software raid). Presently, Ubuntu doesn't seem to know how to handle these, apparently due to mdadm being too old: as far as I know, imsm is supported starting from mdadm V3 and higher. I checked the ubuntu packages, and came to know that v3 will be shipped in the upcoming release 11.04 (natty). The present version of mdadm is below 3. Presently, I use SW raid on many of our servers. But for some customer installations, support of imsm would be nice. Will ubuntu support imsm raids by default? Some relevant info I found on the web: <a href="http://www.expert.tc/topic.php?id=159833">http://www.expert.tc/topic.php?id=159833</a> -> After running <tt>mdadm --assemble --scan</tt> which finds and assembles the container, running <tt>mdadm -I /dev/md/imsm0</tt> assembles the arrays inside the container. <a href="http://www.linuxquestions.org/questions/slackware-14/slackware-13-1-64-bit-with-intel-matrix-storage-manager-807930/">http://www.linuxquestions.org/questions/slackware-14/slackware-13-1-64-bit-with-intel-matrix-storage-manager-807930/</a> -> a guy struggling to get his RAID working on Slackware, which didn't include mdadm v3 yet.
