I think the documentation for using the rps10 fence device is incorrect (http://sources.redhat.com/cluster/doc/cluster_schema_rhel5.html), or else there is a bug in the fence agent in rhel5: The doc does not mention that you must specify an "option" attribute or else the agent returns an error. Eg. <fencedevice agent="fence_rps10" name="rps10" device="/dev/ttyS0" port="0" option="reboot" /> will work but without the "option" attribute you get the error: failed: operation must be 'on', 'off', or 'reboot' Thanks Ben -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
