Configuring Cluster Resources for Shared Linux POSIX Volumes11157novdocx (en) 7 January 201011Configuring Cluster Resources forShared Linux POSIX VolumesThis section describes how to create shared disk partitions and Linux POSIX volumes as clusterresources with Novell Cluster ServicesTM. Section 11.1, “Requirements for Shared Linux POSIX Volumes,” on page 157 Section 11.2, “Creating Linux POSIX Volumes on Shared Disks,” on page 158 Section 11.3, “Cluster-Enabling a Linux POSIX Volume on a Shared Disk,” on page 162 Section 11.4, “Creating a Virtual Server Name for the Cluster Resource,” on page 169 Section 11.5, “Sample Scripts for a Linux POSIX Volume Cluster Resource,” on page 172 Section 11.6, “Expanding EVMS Volumes on Shared Disks,” on page 176 Section 11.7, “Deleting Shared Storage,” on page 178 Section 11.8, “Known Issues for Working with Cluster Resources for Linux POSIX Volumes,”on page 178 Section 11.9, “What’s Next,” on page 17911.1 Requirements for Shared Linux POSIXVolumes EVMS must be installed and running on each server in the cluster. You must install Novell Cluster Services before you create shared disk partitions on sharedstorage (storage area network, or SAN). Cluster Segment Manager (CSM) containers require Novell Cluster Services to be running onall nodes that access the CSM container. Do not create or make to modifications to EVMSobjects unless Novell Cluster Services is running. You should carefully plan how you want to configure your shared storage prior to installingNovell Cluster Services. For planning information, see the following: Section 3.1.4, “Shared Disk System Requirements,” on page 36 Section 3.1.5, “SAN Rules for LUN Masking,” on page 38 Each cluster-enabled Linux volume needs its own static IP address. The IP address is used toprovide access and failover capability to the cluster-enabled volume. The IP address assignedto the volume remains assigned to it regardless of which server in the cluster is accessing thevolume. In a mixed cluster of NetWare ® and OES 1 or 2 Linux nodes, Linux POSIX file systems ascluster resources cannot be created until the entire cluster is migrated to OES 2 Linux. LinuxPOSIX file systems as cluster resources cannot be migrated or failed over to NetWare clusternodes. Only NSS pool cluster resources that are created on a NetWare cluster node can befailed over between Linux and NetWare nodes of a mixed-node cluster.
