Indeed. I do not think we have a tested procedure for renaming a hosted-engine. The rename tool [1] will not handle this. Nikolai - IIRC we discussed this some months ago. Did you eventually test this? You can run the tool, but then ha-agent will fail to connect to the engine to see that it's alive. To answer your question: This is saved in a file called hosted-engine.conf, as 'fqdn='. Until 3.5, this file was only saved locally on each host in /etc/hosted-engine. Since 3.6, it's also saved in the shared storage. You can try extracting it from the shared storage, edit, then update. See e.g. [2] for how to do this, but that one is for a different file (the answer file, also saved in both /etc and the shared storage). I now read parts of the relevant code, and AFAICT we do not use fqdn from the shared storage, only from the one in /etc. So it might be enough to change there (although you risk that this will change in a future version). Please open a bug about this. If you try the above, please tell us if it worked or not and what problems/errors you got. Thanks!
