Hmm, good thought, but I don't think that would be it, since his mdstat
is showing 2 raid-disks for each array.

David, could you send the rest of your log from the time you create the
array until after the hot add? I'm wondering what's in the log when the
hot add is done. Are there errors?

Also, would it be possible to run "mdadm --examine /dev/sd[ab]3" and/or
run this:

perl -e '$io_num = 0x0913; open (FD, "/dev/md2") or die "open: $!";
ioctl(FD, $io_num, $null) or die "ioctl: $!";'

and send the log output, so we can see what's in the superblocks?
