While trying to do a hyperconverged setup and trying to use "configure LV Cache" /dev/sdf the deployment fails. If I dont use the LV cache SSD Disk the setup succeds, thought you mighg want to know, for now I retested with 4.3.3 and all worked fine, so reverting to 4.3.3 unless you know of a workaround?
