from your response i understood that i was using the wrong terms for
explaining my need.
What i'm willing to change the fqdn of the engine vm running on hosted
engine. I've seen that the deployment procedure asked for it, so i
think somewhere this value is used for configurations.
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!
