This tutorial is a brief writeup of setting up the General Parallel Fils System (GPFS) Networked Shared Disk (NSD). For more detailed and comprehensive, do look at for a detailed understanding of the underlying principles of quorum manager.
This tutorial only deals with the technical setupStep 1: PreparationAll Nodes to be installed with GPFS should be installed with supported Operating System; For Linux, it should be SLES and RHEL. The nodes should be able to communicate with each other and password-less ssh should be configured for all nodes in the cluster. Create an installation directory where you can put all the base and update rpm. For example, /gpfsinstall. Copy all the. Build the portability layer for each node with a different architecture or kernel level.
For more information see, For ease of installation, put all the rpm at /gpfsinstallStep 2: Export the path of GPFS commandsRemember to Export the PATH # vim /.bashrc export PATH=$PATH:/usr/lpp/mmfs/binStep 3: Setup of quorum manager and clusterJust a nutshell explanation taken from. Node quorum is the default quorum algorithm for GPFS™. With node quorum:. Quorum is defined as one plus half of the explicitly defined quorum nodes in the GPFS cluster.
There are no default quorum nodes; you must specify which nodes have this role. For example, in, there are three quorum nodes.
