From a2b85d13e50327da721e32071aecad21b10ffb1a Mon Sep 17 00:00:00 2001 From: Pranith Kumar K Date: Thu, 15 Nov 2012 23:07:24 +0530 Subject: cluster/afr: Fail readv on data-split-brain Problem: Afr prevents opens on a file in split-brian but the fd that is already open still has the capability to perform both reads and writes to the file. Fix: Fail readvs on a file with EIO.
