So, on to my next upgrade issue (sorry for all the questions and thanks for everybody's help)... I upgraded my test cluster from 3.5 to 3.6 (latest version of each, all on CentOS 7 except the engine on CentOS 6). Now I'm working on the next step, upgrading to 4.0 and migrating the HE to the appliance. When I went from 3.5 to 3.6, I ended up with an fhanswers.conf in the shared storage that only contained "None"; I fixed that based on some mailing list messages (but just mentioning it in case it could be related). My problem is that the hosted engine storage domain did not get imported into the engine DB, so I can't proceed with "hosted-engine --upgrade-appliance". I didn't see any errors, so I'm not sure how that happened. I'm also not sure how to fix that. Suggestions? -- Chris Adams <cma@cmadams.net>
