2.6 What’s New or Changed in NSS (OES 11)

This section describes enhancements and changes to the Novell Storage Services for Novell Open Enterprise Server 11. The following features are added:

Change in the Volume Manager

Novell Linux Volume Manager (NLVM) replaces the Enterprise Volume Management System (EVMS) volume manager, which is now deprecated. For more information, see the OES 11 NLVM Reference Guide or see the nlvm (8) man page.

Support for Creating >2TB Partition

When you initialize a device, you can choose to use the DOS partition table scheme or the GUID Partition Table (GPT) scheme for a given device.

The DOS partition table scheme supports devices up to 2TB in size. It allows up to four partitions on a device.

The GPT partition table scheme supports device sizes up to 2E64 sectors (that is, up to 8388608 petabytes (PB) based on the 512-byte sector size). It allows up to 128 partitions per disk. Each of its disks partitions is a logical device that is identified by a unique 128-bit (16-byte) GUID.

Support for Creating Linux Volumes

Using the NSSMU and NLVM command line option, you can create Linux volumes. For more information, see Table 9-11, Create Linux Volume in the OES 11 NLVM Reference Guide, the nssmu(8) or the nlvm(8) manpage.

Single Disk System Support

You can now use the system device containing the root partition also to create/manage NSS pools and volumes.

quota Utility is Renamed to nssquota

For more information, see nssquota.

Moving a Pool

Using the NSSMU and NLVM command line option, you can move a pool from one location to another on the same system. For more information, see Table 9-11, Moving a Pool, and the Move in the OES 11 NLVM Reference Guide.

nssraid Utility

The nssraid utility options are soft linked to the Novell Linux Volume Manager nlvm raid options. You can alternatively use nlvm raid commands to manage NSS software RAIDS at the command line and in scripts in OES 11. nlvm raid commands have more options than the nssraid utility.

For information, see RAID in the OES 11 NLVM Reference Guide or see the nlvm man page.
