My guess is you configured the RAID1 array as having 1 disk. Now if you add more disks to it, they are spares. You should have configured the array as having 2 disks, with 1 missing. Then when you add a disk, it will re-build to it. Read about raidreconf. Google it, if needed! It may allow you to modify a RAID1 array. I know it allows you to add a disk to a RAID5 array, but don't know about RAID1. I have never used this tool.

I'm trying to now make the second disk, hdc, a mirror of the first. When I try to add it using mdadm the second disk becomes a spare and no synchronization is done. Is there any way to add the second disk directly as a mirror? Thanks.
