Hi Matthias and Zachary, Thanks for the help - I was able to mount the device after manually attaching. Now, to just figure out the last pieces preventing it from mounting as the root device, which it looks like Zachary's tips should help with.

I did put bcache into /etc/sysconfig/kernel INITRD_MODULES (suse) and generated a new initrd > More tweaks might be necessary, don't know if that already gives you the > udev rules inside the initramfs (it should, if you have bcache-tools > installed which provide initramfs-tools/hooks/bcache). > Regards > Matthias bcache-tools, with the initrd rules, in installed in Suse as well. lsinitrd shows bcache.ko and /usr/lib/udev/bcache-register are present. I'll follow Zachary's tips next - thank you both very much!
