Subject: [PATCH v2] multipath: change default configuration parameters
Date: Thu, 10 Jan 2013 14:05:08 -0600 [thread overview]
Message-ID: <20130110200508.GO19059@ether.msp.redhat.com> (raw)
This patch makes multipath devices default to setting fast_io_fail,
switches the default selector to service-time and removes the
round-robin setting of the builtin device configurations. The goal is
to give multipath devices better performance "out of the box".
