- The document discusses client, server interactions in Glusterfs, including client connection, disconnection, and reconnection. - When a client connects, it first connects to glusterd to get the port for the brick, then connects to the brick to perform operations. On disconnection, resources are cleaned up and reconnection is attempted every 3 seconds. - During reconnection, the client tries to recover resources like open file descriptors by reopening them, though locks are not currently restored.
