I thought the problem [1] would be because of a misconfigured kernel with no devicemapper support, but I think have compiled everything in? I cannot use any other kernels than 2.6.30 or it will not assemble the raid6 (mdadm) so I dont think i have another option than compiling it myself, apt has only 2.6.22 or such
