Does the client track which OSDs are reachable? How does it behave if some are not reachable?
For example: Cluster network with all OSD hosts on a switch. Public network with OSD hosts split between two switches, failure domain is switch. copies=3 so with a failure of the public switch, 1 copy would be reachable by client. Will the client know that it can't reach the OSDs on the failed switch? Well...thinking through this: The mons communicate on the public network -- correct? So an unreachable public network for some of the OSDs would cause them to be marked down, which then the clients would know about. Correct?
