In the past, openaisparser.lcrso was responsible for turning on the
openais services as well as configuring the system. Other systems may
desire to start openais. Now there is a new plugin called
"openaisserviceenable.lcrso" which can be used with any other set of
plugins (such as pacemaker or cman).
To start openais now, you can run the services/aisexec script which
consists of:
[EMAIL PROTECTED] services]$ more aisexec
#!/bin/sh
export
COROSYNC_DEFAULT_CONFIG_IFACE="openaisserviceenable:openaisparser"
/usr/sbin/corosync -f
Or it may be run manually by setting that environment variable as shown
above.
patch attached.
