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 -- Janek Kozicki | - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
