From 25c7533357a4c4a9311d40cc92e9648c8a7e763e Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 18 Sep 2012 17:01:12 -0400 Subject: NFSv4.1: Retry pNFS after a 2 minute timeout If we had to fall back to read/write through MDS, then assume that we should retry pNFS after a suitable timeout period. The following patch sets a timeout of 2 minutes.
