[rdo-users] Scaling integrated Ceph cluster with post deployment customization

[Cody]

Thank you John for the reply.

I am unsure to what extent I should include in an environment file
when it comes to scale a Ceph cluster. Should I include every
customization done to the cluster since previous deployment? In my
case, I have altered the CRUSH hierarchy, changed failure domains, and
created an EC pool with a custom EC rule. Do I need to count in all of
those?

Thank you very much.

Best regards,
Cody
