Appendix A. Using Red Hat GFS with Red Hat Cluster Suite 133
A.3.2. Adding Red Hat GFS to an Existing Red Hat Cluster Manager
Deployment
Adding Red Hat GFS to an existing Red Hat Cluster Manager deployment requires running the Red
Hat GFS druid application, GFS Setup Druid (also known as redhat-config-gfscluster ). As with
the scenario in Section A.3.1 New Installations of Red Hat GFS and Red Hat Cluster Manager , while
Red Hat GFS is scalable up to 300 nodes, a Red Hat Cluster Manager limits the total number of nodes
in a cluster to 16. Therefore, in this scenario, Red Hat GFS scalability is limited. If the 16-node limit
is too small for your deployment, you may want to consider using multiple Red Hat Cluster Manager
clusters.
A.3.3. Upgrading Red Hat GFS 5.2.1 to Red Hat GFS 6.0
To upgrade Red Hat GFS 5.2.1 to Red Hat GFS 6.0, follow the procedures in
Appendix B Upgrading GFS . Running an upgraded version of Red Hat GFS (Red Hat GFS 6.0) with
Red Hat Cluster Manager, requires the following actions:
1. Install and configure Red Hat Cluster Manager.
2. Install and configure Red Hat GFS, configuring the Red Hat GFS CCS files according to the pro-
cedures in Chapter 6 Creating the Cluster Configuration System Files . It is recommended that
you edit the CCS files manually rather than by using the Red Hat Cluster Manager GFS Setup
Druid .
Note
For assistance with installing Red Hat Cluster Manager and performing the Red Hat GFS upgrade in
this scenario, consult with Red Hat Support.
