Creating GPFS cluster


What exactly is a GPFS cluster?

Basic Installing and Configuring of GPFS Cluster (Part 1) | The Linux Cluster

All backed node types, which include Linux, AIX®, and Windows Server, can be used in GPFS clusters. These nodes can all be connected to a single set of SAN storage or via a combination of SAN and network-connected nodes. Nodes can be in a single cluster, or information can be shared between clusters.

A GPFSTM cluster can be configured in numerous ways.

All backed node types, including Linux, AIX®, and Windows Server, can be used in GPFS clusters. These nodes can all be connected to a single set of SAN storage or via a combination of SAN and network-connected nodes. Nodes can be in a single group, or data can be shared between clusters. A cluster can be contained in a single data center or distributed across multiple data centers.

Installing and configuring GPFS entails several steps that must be completed in the correct order. Before starting the setup process, go over the pre-installation and installation guidelines.

Parallel File System in General (GPFS)

IBM’s General Parallel File System (GPFS) is an elevated clustered file plan. It could be used in distributed parallel common disc or shared nothing modes. It is used by many of the world’s largest corporations.

  • GPFS enables the configuration of a highly available file system that allows concurrent access from a cluster of nodes.
  • Cluster nodes can run the AIX, Linux, or Windows operating systems.
  • GPFS provides high performance by stripping data blocks across multiple discs and reading and writing these blocks in parallel. It also provides block replication across multiple discs to ensure file system availability even during disc failures.

Roadmap for Pre-Installation

  1. Create a cluster. Examine and plan your cluster configuration.
  2. Examine the GPFS Requirements. Check that the following minimum requirements are met: • System requirements • Software requirements
  3. Set up the interface Check that you have three interface cards.
  4. Create a network configuration plan.
  5. Examine the firewalls. Before beginning the installation, ensure that all firewalls are turned off.
  6. Turning off SELinux. Turn off SELinux.
  7. Generate FQDNs and hostnames. Make the hostnames and FQDNs.
  8. Remote access. Check to see if all nodes are remotely logged in.
  9. Configuration of storage. Connect discs to all nodes.

  1. Install Nodes correctly. Before installing GPFS, we should ensure that all nodes are installed correctly.
  2. Install the GPFS code.
  3. Set up the GPFS cluster.
  4. Assigning a license to each cluster node
  5. Launch GPFS and check the status of all nodes.
  6. Make NSDs.
  7. Construct file systems.

You should decide on the network topology and information transmission before installing GPFS and deploying the system.

System configuration preparing

Comprehend the quorum, quorum-manager, and nsd-node, and compute node roles. After all the requirements are met, GPFS is managed to install on all nodes.

The quorum, as well as quorum-manager nodes, are in charge of the following tasks:

  • Cluster authority, management, as well as monitoring.
  • Cluster creation.

The nsd-node nodes are in charge of the following tasks:

  • Developing the nsd-devices
  • Producing the stanza files
  • Creating data structures on the cluster.
  • Combined file systems with other cluster nodes.
  • Hard disc sharing on a cluster.

The compute nodes are in charge of the following tasks:

  • Using the shared drive

Carrying out an Installation

  • Creating a Cluster
  • Creating an NSD
  • Creating a File System
  • Mounting a Storage Device
  • A Server Design to install
  • A Memory Architecture to create a file system on
  • A connectivity architecture to support customer’s access to file system information
  • An authentication mechanism to handle access as well as authorization to data
  • An OS to operate Spectrum Scale Software on
  • Spectrum Size Software
  • Spectrum Size Server licenses
  • Spectrum Size Cluster Quorum Devices
  • Spectrum Scale Customer Permits (Optional)
  • Define the installation procedure.
  • The server installation is finished.
  • The network installation is finished.
  • Storage hardware has been installed and is available to the servers.
  • The operating system has been registered and configured.
  • There is GPFS software available.
  • GPFS licenses have been registered and purchased.

Exchanges of information across numerous GPFS clusters

Information can be shared across multiple GPFS clusters using GPFS. After mounting a file system in another GPFS cluster, all information access would be the same if you were in the host cluster. Multiple clusters can be linked within the same data center or over vast distances via a WAN. Every cluster in a multicluster setup can be placed in a different administrative collective, simplifying management or providing a unified view of data across multiple organizations.
