Hello David, Thank you! We setup 2 pools to use EC with RBD. One ecpool and other normal replicated pool.
However, would it still be advantageous to add a replicated cache tier in front of an EC one, even though it is not required anymore? I would still assume that replication would be less intensive than EC computing?
