From ebee985b34dcbef204bc7fd609da9a525467ce67 Mon Sep 17 00:00:00 2001 From: Ryan Haasken Date: Mon, 7 Jul 2014 10:40:16 -0500 Subject: [PATCH] LUDOC-247 mount: Clarify recovery_time_{soft,hard} defaults It was not clear that the recovery_time_{soft,hard} default values depended on the RPC timeout value at mount time. The descriptions of the default values of these recovery times were clarified. Links were added from the recovery_time_{soft,hard} descriptions to the section which describes the RPC timeout.
