From 168b9090c739c4b5556023a3f08789b349ca7339 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Thu, 21 Jan 2016 16:33:19 +0100 Subject: libceph: monc hunt rate is 3s with backoff up to 30s Unless we are in the process of setting up a client (i.e. connecting to the monitor cluster for the first time), apply a backoff: every time we want to reopen a session, increase our timeout by a multiple (currently 2); when we complete the connection, reduce that multipler by 50%.
