I have not been able to find a solution as of yet. My issue deals with nested raid using mdadm, and it seems that upon a reboot mdadm is attempting to assemble the larger array before the smaller component array is created, and thus it is failing. I have a degraded raid 5 array md1 whch is composed of hda1 and md0. Upon a reboot, mdadm attempts to build md1 before md0 is built. It fails, so md1 is not build and I need to assemble it manually. Is there a solution for this? Thanks you for your time, Marc p.s. I would like to also take a second to express my gratitude to Neil Brown for the mdadm utility. I have found it very useful and it has made working with raid in linux very enjoyable and straight-forward!
