Hi,
I've just been re-installing a box, and saw that the wiki says regarding using the mdadm_udev hook:
"This is the preferred method of mdadm assembly (rather than using the above mdadm hook). "
I've tried to use the mdadm_udev hook, but the devices get named:
normal md0 (/boot) is md127 normal md1 (encrypted, then lvm with swap and / on it ) is md126
I found this out with "cat /proc/partitions" once my box failed to boot and dropped to the initramfs shell.
Seems pretty random, the first actual device isn't even the lowest number.
You need to create a file /etc/mdadm.conf. mdadm --examine --scan will generate the right lines for you. This file will be added to the initramfs and your names will be fine again.
