If you were to enable multipath on a non-multipathed root system you need to blacklist the root filesystem. I don't know why I should have to do that. OpenSUSE 13.1 works fine with Swap, / and /srv each on RAID1 md devices and additional multipathed FC LUN's. OpenSUSE 13.2 also assembles SWAP and /, but misses /srv if multipathd.service is enabled.
Also, due to the timing involved multipath might claim the device for MD, so if MD references the devices as raw block devices (ie using /dev/sdX) it won't be able to start. If already written that I have checked that point. While in emergency mode, dmsetup does not report /dev/sd[a,b]3 to be claimed (see #c4). I can manually assemble the missing array and continue booting.
