I have reloaded my OS (SuSE 11.3, FWIW). I have three Linux RAID5 arrays on other disks that were not touched in the reload. The partitions are all there and all should be fine, except I can't figure out how to tell the new OS what the arrays should look like.

I have copies of all my old system files, including mtab and mdadm.conf. I have restored these two files in the new OS.

What I seem to be lacking is some sort of system file that describes which partitions belong to which arrays. I'm sure I have a copy of it from the old OS (I have a copy of everything), but I don't know what it is named or where it is.

Can anyone help me out?
