Description Paul Kennedy 2008-06-11 16:26:29 UTC
Description of problem: Provide example configuration for NFS-GFS configuration in a 5 node cluster. Include specification of clients connection setup and how to manage failover of the servers. This documentation is an example document to supplement existing cluster suite documentation. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Note: This bug is being opened from a use case cited in Bug #233052.

I sent the following email on August 4 to the following review list: To: firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com, firstname.lastname@example.org, email@example.com CC: "Michael H. Smith" <firstname.lastname@example.org>, Steven Bonneville <email@example.com>, Marc Curry <firstname.lastname@example.org> Subject: To Review: Outline of New Cluster Configuration Procedure Doc Enclosed for your review is the outline for the first of several proposed cluster configuration procedure documents. This document will provide a procedure for configuring NFS over GFS in a 5-node Red Hat Cluster using Conga. As documented in Bug 450888, which is a branch off of Bug 233052, we are beginning to document example cluster configuration procedures for "common use" cases. This documentation will supplement existing cluster suite documentation. This first procedural document is for a simple configuration of a single NFS service that can fail over to any of the nodes in the cluster. Once we document this procedure and work out a template for the documentation, we can add procedures for more complicated configurations. Please let me know by Monday, August 11 if you have any comments or suggestions for this document in particular. In addition, if you are able to help in providing other sample cluster configuration procedures you think would be useful, please let me know that as well. You can check out Bug 233052 to see what other cluster configuration procedures we are planning to document down the line. Thank you, -Steven Levine Configuring NFS over GFS in Red Hat Cluster Suite ------------------------------------------------- I. Introduction Description of cluster configuration that this procedure provides: - 5 nodes in a cluster - NFS services over GFS file system - N clients: Will show target configuration of 2 A. Illustration of setup that this procedure will define B. Description of what happens with this configuration: - Cluster Suite assigns server - If server goes down, automatically fails over - Failover invisible to client II. Prerequisite Configuration Description and table of what has been set up beforehand: - 5-Node Cluster - Fencing Devices for each node - Logical volume with GFS filesystem - No failover domain defined: Cluster will take care of administration within system. III. Components to Configure Table of what this procedure will define (spec sheet): - Resources and parameters - NFS service IV. Configuring Resources Procedure for configuring the following resources using Conga, with descriptions of each parameter and its meaning: - IP address - GFS file system - NFS export - NFS clients V. Configuring Service Procedure for configuring an NFS service using Conga, with descriptions of the service parameters and a small discssion of configuring child resources in NFS services: - Name of Service - IP address - GFS Resource - NFS export is a child of GFS - NFS clients are children of NFS export VI. Checking Service Simple instructions for checking that the service is working: - Go to client and execute an NFS mount - Fence the node and check what happens (from client side, and from Conga administration view) VII. The Cluster Configuration File Example of configuration file before the resources and services were defined in this procedure, and after the resources and services were defined for this procedure. VI. Troubleshooting What to check if NFS mount is not working, or if failover is not happening. VIII. General Caveats and Concerns in NFS Configuration - NFS is not cluster aware - Other concerns?

The RHEL 5.3 release includes a new manual documenting configuration of NFS-GFS in a cluster.
