On the Make File System page, choose a Linux POSIX file system interface module from 
the list (such as 

Ext2/3 File System Interface Module

), then click

On the Volumes page, right-click the volume, then select 

Mount

. 

4b

On the Mount File System page, select the volume, then specify the Linux path to use for 
the mount point, such as 

/mnt/mount_point

Continue with 

Section 11.3, “Cluster-Enabling a Linux POSIX Volume on a Shared Disk,” on 

page 162

.

11.3  Cluster-Enabling a Linux POSIX Volume on 

a Shared Disk

In order to cluster-enable the Linux POSIX volume that you created in 

Section 11.2, “Creating 

Linux POSIX Volumes on Shared Disks,” on page 158

, you must create a cluster resource for it. The 

cluster resource allows the shared disk and its contents to be moved or mounted on different servers 
in the cluster. The cluster resource provides a way for clients to automatically reconnect to the 
volume regardless of which server is hosting it. 

IMPORTANT: 

You can create an NCP (NetWare

®

 Core Protocol

TM

) volume on the shared Linux 

POSIX volume and cluster-enable the shared NCP volume. For information, see “

Configuring NCP 

Volumes with Novell Cluster Services

” in the 

OES 2 SP2: NCP Server for Linux Administration 

Guide

.

EVMS containers are the unit of failover for Linux POSIX volumes. Because the EVMS container 
is the unit of failover, all volumes in a container also fail over, but only the volumes that are 
mounted through the cluster resource load script are automatically mounted on failover. Any 
volumes in the container that are not mounted through the resource load script must be mounted 
manually.

Perform the tasks in this section to create and configure a new cluster resource. You can modify the 
cluster resource settings afterwards by using the 

Clusters > Cluster Options > Properties

 option in 

iManager.
