8.7. Configuring Debug Options
You can enable debugging for all daemons in a cluster, or you can enable logging for specific cluster processing.
To enable debugging for all daemons, add the following to the
/etc/cluster/cluster.conf. By default, logging is directed to the /var/log/cluster/daemon.log file.
<cluster config_version="7" name="rh6cluster"> <logging debug="on"/> ... </cluster>
To enable debugging for individual cluster processes, add the following lines to the
/etc/cluster/cluster.conf file. Per-daemon logging configuration overrides the global settings.
<cluster config_version="7" name="rh6cluster">
...
<logging>
<!-- turning on per-subsystem debug logging -->
<logging_daemon name="corosync" debug="on" />
<logging_daemon name="fenced" debug="on" />
<logging_daemon name="qdiskd" debug="on" />
<logging_daemon name="rgmanager" debug="on" />
<logging_daemon name="dlm_controld" debug="on" />
<logging_daemon name="gfs_controld" debug="on" />
</logging>
...
</cluster>
For a list of the logging daemons for which you can enable logging as well as the additional logging options you can configure for both global and per-daemon logging, see the
cluster.conf(5) man page.
