Dave, I suspect this is the same problem I had two weeks ago. Search for my thread called: "How does grub assemble a RAID1 for / ??" and read that for background. If I'm correct this is a metadata issue. You have two choices: 1) What I think you've done is create the RAID1 without specifying --metadata=0.90. If that's correct then you __must__ use an initramfs to load mdadm. I'm studying how to do that myself. 2) Rebuild the RAID1 specifying --metadata=0.90 which is the only metadata type that the kernel can auto-assemble for you at boot time without an initramfs, and what I'm currently using here. Hope this helps, Mark
