From bb71e4a5d7eb151aa8d4e98c628b744f78af7c57 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 27 Apr 2017 11:22:07 -0400 Subject: [PATCH] pNFS: Allow multiple connections to the DS If the user specifies -onconnect= mount option, and the transport protocol is TCP, then set up connections to the pNFS data server as well. The connections will all go to the same IP address.
