2.2 What’s New (OES 11 SP1)

The NLVM and NSSMU management tools support Linux POSIX volumes on OES 11 SP1 running on 64-bit SUSE Linux Enterprise Server (SLES) 11 Service Pack (SP) 2.

NSSMU

In addition to bug fixes, NSSMU provides the following changes and enhancements for Linux POSIX volume management in the OES 11 SP1 release:

NLVM Commands

In addition to bug fixes, NLVM commands provide the following changes and enhancements for Linux POSIX volume management in the OES 11 SP1 release:

Btrfs File System

NSSMU, NLVM Linux commands, NCP Server, and Novell Cluster Services were modified to support the Btrfs file system for Linux volumes. The Btrfs file system is now available as an alternative to other supported file systems (Ext2, Ext3, Reiserfs, and XFS) when you create a Linux volume. The btrfsprogs package is required. You can use NSSMU or NLVM to manage the Btrfs volumes as you would manage other Linux data volumes. Btrfs volumes can also be configured for NCP file access and for clustering with Novell Cluster Services.

SUSE Linux Enterprise Server (SLES) 11 Service Pack 2 (SP2) also supports the Btrfs file system in the YaST2 Partitioner. You can use the Partitioner during the system installation to configure a Btrfs solution for the system device. YaST2 automatically installs the btrfsprogs package if you use Btrfs for the root (/) file system. Bootloader support for /boot on Btrfs is not available in SLES 11 SP2; it is planned to be available beginning in SUSE Linux Enterprise 12.

For information about the features of Btrfs, see Btrfs in the OES 11 SP1: Linux POSIX Volume Administration Guide.

NCP Volumes and Cluster Resources

NSSMU and NLVM were modified to support the creation of NCP volumes on Linux POSIX file systems. You can NCP enable Linux POSIX volumes, an LVM volumes, and clustered LVM volumes as you create them. When you enable NCP for a Linux volume, an NCP volume of the same name (using all capital letters) is automatically created. An NCP share is created at the root of the Linux volume.

For clustered LVM volumes, the NCP Virtual Server object is automatically created and the NCP mount, dismount, and status commands are added to the scripts for the LVM volume group cluster resource. The Novell Cluster Services Generic File System template is used to specify the default cluster policies and scripts for the cluster resource. After you create the resource, you can use the Clusters plug-in for iManager to set up preferred nodes for the resource and to manage the resource.
