Comment 2 for bug 285156

Oh, meant to attach my current md status, which shows the problem very well:

md1 : active raid10 sdc3[3](S) sda3[0] sdb3[1]
      113859584 blocks 512K chunks 2 near-copies [3/2] [UU_]

I've added a new drive, md knows it exists, md knows there's a drive missing... but it doesn't sync. No amount of removing and re-adding the drive makes it sync.
