Comment 17 for bug 368986

It's almost unbelievable that mdadm (and so software RAID) does not work on Ubuntu (and since so much time!). Please note that the patch it's a one-liner... Also please note that software RAID it's one way (the only one?) to get better performance from disks on the cloud (e.g. RAID0/striping helps parallelizing I/O requests with AWS EBS) and Ubuntu is investing so much in cloud computing.

BTW thanks nsrderooy for the patch, I applied it successfully but RAID continued to not work (maybe a kernel/initrd problem?).
