from your response i understood that i was using the wrong terms for=20
explaining my need.=20
=20
What i'm willing to change the fqdn of the engine vm running on hosted=20
engine. I've seen that the deployment procedure asked for it, so i=20
think somewhere this value is used for configurations.=20
Indeed. I do not think we have a tested procedure for renaming=20
a hosted-engine.=20
The rename tool [1] will not handle this.=20
Nikolai - IIRC we discussed this some months ago. Did you eventually=20
test this?=20
You can run the tool, but then ha-agent will fail to connect to the engine=
=20
to see that it's alive.=20
To answer your question: This is saved in a file called hosted-engine.conf,=
=20
as 'fqdn=3D'. Until 3.5, this file was only saved locally on each host in=
=20
/etc/hosted-engine. Since 3.6, it's also saved in the shared storage.=20
You can try extracting it from the shared storage, edit, then update.=20
See e.g. [2] for how to do this, but that one is for a different file=20
(the answer file, also saved in both /etc and the shared storage).=20
I now read parts of the relevant code, and AFAICT we do not use fqdn=20
from the shared storage, only from the one in /etc. So it might be=20
enough to change there (although you risk that this will change in=20
a future version).=20
Please open a bug about this. If you try the above, please tell us if=20
it worked or not and what problems/errors you got. Thanks!=20
