I really cannot help you until you show me the output of "mdadm --assemble
--verbose ..." like I asked.

I really WAS NOT lying!

I just did it again, and redirected output to a file

The file ( located on my USB stick) contains:

mdadm: looking for devices for /dev/md1
mdadm: no devices found for /dev/md1

If I can butt in here... presumably while the system can't assemble your array, you're running from rescue media or whatever? You may not have a suitable mdadm.conf in the rescue environment.

If you haven't already posted `mdadm --examine --scan --verbose --verbose` aka `mdadm -Esvv`, or at the very least `mdadm --examine --verbose /dev/sd[abc][12]`, then please do.

Please also try `mdadm --assemble --scan --verbose` and post the result.

Another thing that occurs to me is that since you said you had CentOS 4, you likely have kernel 2.6.9 and mdadm 1.12 which are very old. You might try SystemRescueCD or similar to get a mdadm 3.1.x which will be much better at finding and fixing any problems.

Cheers,

John.
