4.1 NetStorage Installation and Configuration

OES NetStorage software is included with OES. It can be installed during the OES installation, or afterwards by using YaST > Open Enterprise Server > OES Install and Configuration. You must select the OES NetStorage component check box to install NetStorage. Because NetStorage requires iManager and Apache, you must also select the Web and Lamp Server and iManager check boxes. See Section 3.0, Installing NetStorage for more information on installing and configuring NetStorage.

Because most networks require NetStorage to be installed on only one server, it is generally only necessary to install NetStorage on two servers in the cluster. Users gain access to files and folders by connecting to one NetStorage server. The other NetStorage server acts as a backup in case the first NetStorage server fails. The following figure shows how a typical NetStorage cluster configuration might look.

Figure 4-1 Cluster Configuration for NetStorage on Linux

When you install NetStorage with OES, you are asked to specify the DNS name or IP address of the Primary eDirectory Server. This is the IP address or registered DNS name of a server in your eDirectory tree that has the master replica or a read/write replica of eDirectory. For NetStorage to function properly in a cluster, you must specify same DNS name or IP address of the primary eDirectory Server on all servers in the cluster that have NetStorage installed.

Any NetStorage-specific configuration changes made to one NetStorage server must be made on all other NetStorage servers in the cluster. In order for NetStorage to function properly with OES Cluster Services, all NetStorage servers in the cluster must be identically configured.
