I have a suggestion to improve our logging config.  The format below is the
default configuration (more or less, the corosync systems aren't sending
anything to syslog, but cman.log seems full of "info"-like stuff, but it's
beside the point):

       <logging to_syslog="yes" to_logfile="yes" syslog_facility="daemon"
                syslog_priority="info" logfile_priority="info">
           <logging_subsys="qdiskd"
                    logfile="/var/log/cluster/qdisk.log"/>
           <logging_subsys="groupd"
                    logfile="/var/log/cluster/groupd.log"/>
           <logging_subsys="fenced"
                    logfile="/var/log/cluster/fenced.log"/>
           <logging_subsys="dlm_controld"
                    logfile="/var/log/cluster/dlm_controld.log"/>
           <logging_subsys="gfs_controld"
                    logfile="/var/log/cluster/gfs_controld.log"/>
           <logging_subsys="rgmanager"
                    logfile="/var/log/cluster/rgmanager.log"/>
           <logging_subsys="CLM"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="CPG"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="MAIN"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="SERV"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="CMAN"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="TOTEM"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="QUORUM"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="CONFDB"
                    logfile="/var/log/cluster/cman.log"/>
           <logging_subsys="CONFDB"
                    logfile="/var/log/cluster/cman.log"/>
       </logging>

Now, I just realized that I've missed some corosync subsystems, EVT, and CKPT
is probably one?, and maybe some others, I don't know.  The point is, to make
a change to "corosync" in general, a user has to go and list every single one
of these things, repeating the same info for each.  That's a big pain, and
definately not intuitive.  I realize it can be useful to enable debugging for
select corosync subsystems, so that should still be possible.

I suggest the following, notice the final "corosync" entry,

       <logging to_syslog="yes" to_logfile="yes" syslog_facility="daemon"
                syslog_priority="info" logfile_priority="info">
           <logging_daemon="qdiskd"
                    logfile="/var/log/cluster/qdisk.log"/>
           <logging_daemon="groupd"
                    logfile="/var/log/cluster/groupd.log"/>
           <logging_daemon="fenced"
                    logfile="/var/log/cluster/fenced.log"/>
           <logging_daemon="dlm_controld"
                    logfile="/var/log/cluster/dlm_controld.log"/>
           <logging_daemon="gfs_controld"
                    logfile="/var/log/cluster/gfs_controld.log"/>
           <logging_daemon="rgmanager"
                    logfile="/var/log/cluster/rgmanager.log"/>
           <logging_daemon="corosync"
                    logfile="/var/log/cluster/corosync.log"/>
       </logging>

the corosync entry would apply to *all* corosync subsystems by default.
We can still allow per-subsystem configuration,

           <logging_daemon="corosync" subsys="QUORUM"
                    logfile="/var/log/cluster/corosync-quorum.log"/>
           <logging_daemon="corosync" subsys="TOTEM"
                    logfile="/var/log/cluster/corosync-totem.log"/>
           ...
