From c13c1fd5a487eeca269e8b62114f607487ee30f6 Mon Sep 17 00:00:00 2001 From: Vijaikumar M Date: Tue, 13 May 2014 17:36:01 +0530 Subject: glusterd: Disable ping-timer between glusterd and brick process When there are too many IO happening, brick process epoll thread will be busy and fails to respond to the glusterd pick packet within 30sec. Also epoll thread can be blocked by a big-lock. Solution is to disable ping-timer by default and only enable where ever required Later when the epoll thread model changed and made lighter, we need to revert back this change. http://review.gluster.com/3842 is one such approach.
