Thanks for the reply, I did not find any documentation on Suse/Novell website to assist with the config, I'm sure they have other customers that would think that bcache does not work or is bugged. Dependencies should be added to bcache_tools for SLES12 that will point to the specific Development Kit tools i.e. libraries that are needed. As for me I'll stop the script I created, reboot; and then try modprobe bcache.
