I'm using the MDADM version and not DMRAID. It has been working fine other than a couple minor issues with clean shutdowns that I fixed by tweaking a couple of the scripts under /etc. I upgraded to the latest Linux kernel (3.2.0-51) and my FakeRAID stopped working, probably because auto-detection failed to see the RAID array. Everything works fine with the previous kernel image, 3.2.0-49. Here is /proc/mdstat with the 3.2.0-49 generic kernel image: Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] md126 : active raid1 sdb[1] sdc[0] 976758784 blocks super external:/md127/0 [2/2] [UU] md127 : inactive sdb[1](S) sdc[0](S) 6306 blocks super external:imsm The /proc/mdstat file is empty (other than listing personalities) in 3.2.0-51. Note that the sdb and sdc drives are recognized by 3.2.0-51, and their partition tables look reasonable, so I don't see any issues with 3.2.0-51 actually seeing the physical drives. The problem appears to be that the MD driver doesn't detect the external RAID (aka 'imsm') metadata created by Intel fakeraid. Here's the additional data requested for new bug reports: lsb_release -rd Description: Ubuntu 12.04.2 LTS Release: 12.04 apt-cache policy linux-image-3.2.0-51-generic linux-image-3.2.0-51-generic: Installed: 3.2.0-51.77 Candidate: 3.2.0-51.77 Version table: *** 3.2.0-51.77 0 500 http://us.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu/ precise-security/main amd64 Packages 100 /var/lib/dpkg/status FWIW, here's the apt-cache data on the previous kernel where fakeraid worked correctly: apt-cache policy linux-image-3.2.0-49-generic linux-image-3.2.0-49-generic: Installed: 3.2.0-49.75 Candidate: 3.2.0-49.75 Version table: *** 3.2.0-49.75 0 500 http://us.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status I will attach the kernel.log for booting 3.2.0-49 and 3.2.0-51. I've looked at them and all I see is that 3.2.0-49 'binds' the RAID array components and 3.2.0-51 doesn't. Here's a snippet from 3.2.0-49 where it starts my RAID. This is absent in 3.2.0-51.

There's no point bisecting the kernel images given the regression has just appeared in 3.2.0-51 and, AFAIK, there was never a release of a '3.2.0-50' kernel. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
