The storage file systems, management tools, and file access protocols support OES 11 SP1 running on 64-bit SUSE Linux Enterprise Server (SLES) 11 SP2. The following changes and enhancements are available for file system management in Novell Open Enterprise Server 11 SP1:
Btrfs: Support was added for the Btrfs file system. The Novell Storage Services (NSS) Management Utility (NSSMU), Novell Linux Volume Manager (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: You can NCP enable Linux volumes as you create them by using NSSMU or the nlvm create linux volume command. For information, see the following:
NCP Trustee Report:
The NCP Trustee Report in Novell Remote Manager can be used to generate reports for an NSS volume, including a Dynamic Storage Technology shadow volume comprised of two NSS volumes. For information, see
Generating and Viewing NCP Trustee Reports for NSS Volumes in the OES 11 SP1: Novell Remote Manager Administration Guide.
