Someone posted this somewhere else:
"ok, what seems to be the problem is that MD device doesn't get running automaticly.
What happens when you run command "mdrun"?
Do you get /dev/md0 manually running by using mdstat with --assemble parameter?
If later, but not first. There is some problem with mdrun script.
Also, have you changed the type of /dev/hda1 to raid autodetect? If not, you have to explicityl help mdrun (eg. by using some conffile of mdadm) to make it scan also that device."
mdrun gave this:
md: md0 stopped
md: could not lock hda1
md: md_import_device returned -16
mdadm: failed to add /dev/hda1 to /dev/md0: device or resource busy
md: bug in file drivers/md/md.c, line 1513
md: o **********************************
md: Complete raid state printout
md: o **********************************
md0:
md: o **********************************
mdadm: failed to RUN_ARRAY /dev/md0: invalid argument
About your other two questions:
1. mdadm --assemble --scan gives "mdadm: no arrays found in config file"
2. The partition-type is set to (fd): Linux Raid autodetect
Thanks for all your help linuxlala! Don't worry about not being able to help, you have helped me a great deal already (I wouldn't be as far as I am now without your help and advice, honestly).
I have started a similar thread in a different forum, have a look and perhaps you can add some advice there as well!
