Is there a log file I can check to find out WHY a drive is not being added? It's been a while since the reboot, but I did find some entries in dmesg - I'm appending both the md lines and the physical disk related lines. The bottom shows one disk not being added (this time is was sda) - and the disk that gets skipped on each boot seems to be random - there's no consistent failure: [...] md: raid10 personality registered for level 10 [...] md: Autodetecting RAID arrays. md: autorun ... md: ... autorun DONE.
