2.4 What’s New (OES 11)

The Novell Linux Volume Manager (NLVM) replaces the Enterprise Volume Management System (EVMS) for the management of Novell Storage Services (NSS) storage objects in Novell Open Enterprise Server (OES) 11. For information about NLVM commands and usage, see the OES 11: NLVM Reference.

NLVM provides the same media management functionality that was used by NSS in EVMS, and makes the following enhancements for OES 11:

  • Initialize a Device with a DOS or GPT Partitioning Scheme: The nlvm init command allows you to specify partitioning scheme format of MS-DOS (the default) or GPT. MS-DOS has a 2 TB size limit. Devices of any size can be configured with GPT.

  • 8 TB Device Size for Pools: The nlvm create pool command allows you to use devices up to 8 TB in size. The maximum pool size is 8 TB. Previously, pools could use devices of up to 2 TB in size.

  • Move Pool: The nlvm move command allows you to move an NSS pool from one location to a new location on the same system.

    See also the related commands:

  • Rescan: The nlvm rescan command performs a rescan of the storage objects (such as partitions, NSS pools, and NSS software RAIDs) on known devices, and creates or updates any Device Mapper device or partition objects as needed.

  • Expand Partition: The nlvm expand partitioncommand allows you to expand a partition by using free contiguous space that follows the partition.

  • Create Linux Volume: The nlvm create linux volume command allows you to create a volume with a Linux POSIX file system. The volume can be created as a traditional Linux volume or as a Linux Logical Volume Manager 2 (LVM2) volume on an LVM2 volume group. If the device is shared with nodes in a Novell Cluster Services cluster, you can cluster-enable the LVM2 volume group.
