The Sun Cluster Data Service for Network File System (NFS) contains procedures to install and configure Sun Cluster HA for NFS on your Sun Cluster nodes.

This document is intended for system administrators with extensive knowledge of Sun software and hardware. Sun Cluster Data Service for Network File System (NFS) Guide for Solaris OS explains how to install and configure Sun™ Cluster HA for Network File System (NFS) on both SPARC® and x86 based systems.

Note – In this document, the term “x86” refers to the Intel bit family of microprocessor chips and compatible microprocessor chips made. Sun’s Network File System (NFS) One of the first uses of distributed client/server computing was in the realm of distributed file systems.

In such an environment, there are a number of client machines and one server (or a few); the server stores the data on its disks, and clients request data through well-formed protocol Size: KB.

NFSv2 was the standard protocol followed for many years, designed with the goal of simple and fast server crash recovery. Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) inallowing a user on a client computer to access files over a computer network much like local storage is accessed.

NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. The NFS is an open standard. Network File System. The Network File System (NFS) is one of the oldest and at the same time one of the most broadly deployed distributed file systems in computing installations.

Originally conceived at Sun Microsystems init is currently an open standard that has spurred many implementations, including several open-source versions. Case Study SUN NFS - VFS Virtual File System (VFS) interface defines the operations that can be done on a filesystem The virtual file system layer has one VFS structure for each mounted file system and one v-node per open file.

A VFS structure relates a remote file system to the local directory on which it is mounted. The Sun Network Filesystem (NFS) provides transparent, remote access to filesystems. Unlike many other remote filesystem implementations under UNIX, NFS is designed to be easily portable to other operating systems and machine architectures.

It uses an External Data Representation (XDR). Lustre is a type of parallel distributed file system, generally used for large-scale cluster name Lustre is a portmanteau word derived from Linux and cluster. Lustre file system software is available under the GNU General Public License (version 2 only) and provides high performance file systems for computer clusters ranging in size from small workgroup clusters to large-scale.

4 Sun Cluster Data Service for NFS Guide for Solaris OS • DecemberRevision A Preface. Sun Cluster Data Service for NFS Guide for Solaris OS explains how to install and configure SunTM Cluster HA for Network File System (NFS) on both SPARC® based systems and x86 based systems. Cluster File System Performance The Sun™ Cluster product provides a highly available cluster platform for hosting applications that range across a broad spectrum that is as diverse as relational databases and web services.

The file system is an important feature for most of these applications, both in terms of functionality and performance. References: Distributed Systems: Concepts and Design by George Coulouris, Jean Dollimore, and Tim Kindberg sun network file system is exaplained in details.

Sun Cluster 12/01 Software. Sun Cluster 12/01 software is the version of Sun Cluster software that supports the configuration described in this article. Previous versions of Sun Cluster software do not support the hardened configurations described in this article.

NFS-share the file system. The following is a general description of how to NFS-share a file system in an Oracle Solaris Cluster environment. For more information on NFS-sharing file systems that are controlled by HAStoragePlus, see Sun Cluster Data Service for Network File System (NFS) Guide.

Locate the dfstab. resource-name file. enables Sun cluster to failover local file systems (to failover, local file system must reside on global dgs with affinity switchovers enabled) Data Service Agent — is a specially written software that allows a data service in a cluster to operate properly.

Data Service Agent (or Agent) does the following to a standard application. Preparing to register and configure the SUN Cluster HA for “ora” Data Service # su - root (to node1) # scstat -p (Check that your cluster is active.) # df -k (check that the /global/ora file system is mounted.) # vi /etc/ (check to see line - “cluster files nis” if not add it.).

The Andrew File System heavily influenced Version 4 of Sun Microsystems' popular Network File System (NFS). Additionally, a variant of AFS, the Distributed File System (DFS) was adopted by the Open Software Foundation in as part of their Distributed Computing Environment. Finally AFS (version two) is the predecessor of the Coda file system.

A file system manages the data storage and retrieval between the operating system (OS) and the storage sub-system. For example, a single personal computer with Windows will usually implement NTFS or FAT on the local disk, while Linux supports a variety of file systems such as ext2, ext3, ext4, XFS, JFS and others.

I have created a global file system on our Sun Cluster system. The global file system is ufs and appears to be setup correct. When I move or copy large amounts of data to the gfs, my Sun Cluster primary node never frees up memory.

The global file system takes up all memory and eventually locks up the entire cluster. Generic Data Service, as the name suggests, is a generic agent designed by Sun Cluster Engineering. GDS takes as an input, scripts to start, stop, validate, and probe an application.

Instead of writing a separate agent for your application, you just write scripts to start, stop, validate, and probe your application and supply these scripts as. Each Sun-supplied data service, such as the highly available network file system (HA-NFS), automatically starts its own fault monitoring processes.

The data service fault monitors verify that the data service is functioning correctly and providing its intended service. The NFS. A primary advantage of using NFS in your cluster is that it is readily available and part of most Linux distributions.

Its familiarity also is an advantage to most UNIX or Linux system administrators, who are able to deploy NFS almost in their sleep.

The knowledge needed to tune and scale an NFS server and the associated clients, however, is not as readily available or applied as. The primary node for the file system is always the same as the primary node for the device on which it is built" The GFS is also known as Cluster File System or Proxy File system.

Our client believes that they can have their application "scaled" and all nodes in the cluster can have the ability to write to the globally mounted file system. Oracle Solaris Cluster (sometimes Sun Cluster or SunCluster) is a high-availability cluster software product for Solaris, originally created by Sun Microsystems, which was acquired by Oracle Corporation in It is used to improve the availability of software services such as databases, file sharing on a network, electronic commerce websites, or other applications.

Select the Activate Cluster checkbox, as shown in Fig to indicate that this server pool will be part of a cluster. Also select Network File System rather than Physical Disk, because we'll be using shared storage on the Sun ZFS Storage Appliances. Figure Create Server Pool Dialog Box.

A clustered file system is a file system which is shared by being simultaneously mounted on multiple are several approaches to clustering, most of which do not employ a clustered file system (only direct attached storage for each node). Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the.

Oracle is by far and away the most popular service running on Sun Cluster Cluster supports highly available (HA) Oracle, Oracle Parallel Server (OPS) and Oracle Real Application Cluster giving users a very wide it is the breadth of release, operating system and platform coverage that drives its appeal.

Solaris Cluster Manager also highlights faults in the system with a red marker over the components that have errors. Solaris Cluster Wizards. As with the clsetup menu-driven command, Solaris Cluster Manager has several wizards to help you set up some common highly available services, such as Network File System (NFS), Apache web server, and Oracle databases, as well as two.

As the name implies, shared file systems provide ways of sharing data between more than one system. Examples of shared file systems are network file system (NFS), common internet file system (CIFS), the Sun TM Cluster Proxy File System (PxFS), and the Shared Writer feature of QFS (QFS/SW).

Most shared file systems require a supporting local.To disable a network, in Failover Cluster Manager, click Networks, click the network, click the Properties action, and then select Do not allow cluster network communication on this network. Alternatively, you can configure the Role property of the network by using the Get-ClusterNetwork Windows PowerShell cmdlet.
