From 592fafe644bf3a48b9e00e182a67d301493634fc Mon Sep 17 00:00:00 2001 From: Steve French Date: Tue, 3 Nov 2015 10:08:53 -0600 Subject: Add resilienthandles mount parm Since many servers (Windows clients, and non-clustered servers) do not support persistent handles but do support resilient handles, allow the user to specify a mount option "resilienthandles" in order to get more reliable connections and less chance of data loss (at least when SMB2.1 or later). Default resilient handle timeout (120 seconds to recent Windows server) is used.
