Here a screenshot http://imgur.com/8pQgG8g Making changes to /etc/fstab didn't seem to work and nor did manually adding device=/dev/sda1,device... in the GRUB config itself.

I'll file a bug report but I'm not sure whether this is a GRUB or an initrd / initramfs problem. Getting a persistent fix required a bodge in /etc/grub.d/10-linux As for support, I don't think it is considered stable in 14.04 but I haven't had to do anything special to use it and used to official installer to get where I am (converting the single disk FS to a RAID1 after). In any case, thanks for the help :)
