Hey folks: Some Background =============== For customers using GFS who would like to setup fencing with the RILOE method: how to setup fencing depends on the device and method being used. That's in Section 10.2 of the GFS 6.0 doc - Fencing Methods http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-fence-methods.ht ml RILOE is there and supported, obviously. The documentation for GFS 6.0 instructs the use of the deprecated fence_rib fencing agent for the RILOE. The examples there for the RILOE method are good in the 6.0 doc: Format for fence.ccs: http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-sf-fence.html#FI G-FENCE-RIB Example of a RILOE fence.ccs: http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-sf-fence.html#EX -FENCE-RILOE Format for nodes.ccs: http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-sf-nodes.html#FI G-SF-NODESRILEOSINGLE Example of a RILOE nodes.ccs http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-sf-nodes.html#EX -SF-RILOE As you know, I'm sure, the fence_rib agent has been deprecated. The fence_ilo agent should be used instead, according to multiple references including the man pages for both. I hoped to find some explicit examples of the two files in the documentation for GFS 6.1 using fence_ilo, but the documentation has changed. Specifically, the GFS Admin Guide has a short: "Fencing is configured and managed in Red Hat Cluster Suite. For more information about fencing options, refer to Red Hat Cluster Suite Configuring and Managing a Cluster." That particular section is here: http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-config-fence -devices.html You'll note that it's not anywhere near the detail as the above GFS 6.0 documentation, as it's GUI-based. The man page for fence_ilo(8) indicates the following fields are used: action = The action required. reboot (default), off, on or status. agent = This option is used by fence_node(8) and is ignored by fence_ilo. hostname = IP address or hostname of the iLO card. login = Login name. passwd = Password for login. ribcl = RIBCL protocol to use. Default is to autodetect. verbose = Verbose mode. Since agent is ignored, looks like we can simply add the "action" parameter to the fence.ccs? I guess action is analogous to the drop-down menu at the top of the GUI? And ribcl and verbose can safely be left alone? They're not in the GUI fields. Questions ========= So, I'm wondering: does anyone have an example of a working fence.ccs and nodes.ccs for GFS 6.1 when using RILOE? I don't have a GFS 6.1 config to work on just now. Also, it appears that this is the way to test? # fence_ilo -v -a ipaddr -l login -p passwd -o off Kind regards Phil -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
