Sachin Punadikar has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1208717?usp=email ) Change subject: SAL: IP based recovery object for "rados_cluster" ...................................................................... SAL: IP based recovery object for "rados_cluster" Usually this recovery backend objects for “rados_cluster” backend are named using nodeid. For enabling movement of an IP (which being served by one Ganesha instance) to another Ganesha instance, IP based recovery backend is required. In such scenario, Ganesha will read this backend and allows reclaim of the clients those were connected to that IP. This mechanism will help in achieving load balancing or IP movement from one node to another easily. How this works - 1. Ganesha started with “-V” option, which will input the IP address Ganesha will listen by default. 2. Ganesha config parameter RecoveryBackendIPBased set to true in NFSv4 block. 3. For “rados_cluster” as recovery backend, based on above 2 steps recovery objects based on IP address will be created & used. 4. While adding or removing a client record, the server address to which the client was connected will be used to identify the recovery object name. 5. For an event TAKE_IP, it will use the passed in IP address to identify and use the recovery object. Ganesha will enter in grace and reclaim of these connected clients will happen.
