question about rbd_read_from_replica_policy

[Noah Elias Feldt <N.Feldt@xxxxxxxxxxx>]

Hello,

I have a question about a setting for RBD.

How exactly does "rbd_read_from_replica_policy" with the value "localize" work?

According to the RBD documentation, read operations will be sent to the closest OSD as determined by the CRUSH map. How does the client know exactly which OSD I am closest to?

The client is not in the CRUSH map. I can't find much more information about it. How does this work?

Thanks
