[Pacemaker] How to configure Pacemaker to obtain quorum from Corosync

[Mars gu]

hi,

I want Pacemaker use quorum iface with corosync,the following Corosync-based options are possible:

******************

1. corosync + pacemaker plugin (v0)

2. corosync + pacemaker plugin (v1) + mcp

3. corosync + cpg + cman + mcp

4. corosync + cpg + quorumd + mcp

******************

When I use option1/option2,  .../cmd/cluster/corosync.c    function crm_connect_corosync 

did not think I configured Pacemaker to obtain quorum from Corosync

I don't want to use cman because quorum and gfs will use different iface.

If option1/2 would not work.May I use option4 ,and where is quorumd?
