Details

Description:
The current kernel (2.6.30-ARCH) is not configured with CONFIG_MD_AUTODETECT. Therefore, it does not probe and assemble software RAID arrays while booting.

All that is required is to set "CONFIG_MD_AUTODETECT=y" in the kernel configuration.

Additional info:
Package version : kernel26-2.6.30.5-1

Steps to reproduce:
N/A

IIRC autodetection is deprecated and should be handled elsewhere (mkinitcpio). Please take a look at the mdadm mkinitcpio hook to initialize your arrays during boot.

Yes this is done by the mdadm hook in archlinux.

AFAIK this would also require the raid modules to be built inside the kernel instead of as module.

as far as i remember yes, this is a won't implement we use initrd for assembling those things, for more flexibility
