Thanks for your confirmation. I cannot explain this behaviour - I
just started using mdadm. If anybody here wants, I can remove the
drive and add this again, to see if I can duplicate this "bug" (?).
If so - then tell me what debug information you do need and I will
give it to you.

Anyway, it seems that this command 

  mdadm --assemble --update=resync /dev/md1 /dev/hda3 /dev/sda3 /dev/hdc3

worked, becasue `mdadm -D /dev/md1` says that array is in
"State : active" (not degraded).

best regards
