My question is: My question is: How to recover a Controller node from
an accidental deletion?
Last weekend, my company programmed an electricity cut to make some
tests. to avoid harms in our production environment, so we decided to turn
it off using the procedure described here:
and to turn it on we follows:
We started the node "Fuel Master" without problems. However, when we
started the controller 1, the problems began:
because of an old "Cluster Manager" installation that shouldn't be started,
the Controller1 was overwritten with another operating system.
Now, I need to recover the controller1 maybe using the controller2.
Please, can you tell me the procedure to do that?
Thanks in advance.
