Blob Blame History Raw
From bf7d9cb56b80314a8c936ae01d2d755aefa93e16 Mon Sep 17 00:00:00 2001
From: Kaleb S. KEITHLEY <kkeithle@redhat.com>

Subject: [PATCH 115/129] common-ha: cluster setup issues on RHEL7

 * use --name on RHEL7 (later versions of pcs drop --name) we guessed
   wrong and did not get the version that dropped use of --name option
 * more robust config file param parsing for n/v with ""s in the value
   after not sourcing the config file
 * pid file fix. RHEL6 init.d adds -p /var/run/ganesha.nfsd.pid to
   cmdline options. RHEL7 systemd does not, so defaults to
   /var/run/ganesha.pid.
