Brief Overview

The Novell Storage Services (NSS) File System is the default file system for NetWare 6 and later. Its many features and capabilities include visibility, a trustee access control model, multiple simultaneous namespace support, native Unicode, user and directory quotas, rich file attributes, multiple data stream support, event file lists, and a file salvage sub-system. These features can help you effectively manage your shared file storage for any size of organization, scaling management of the system for even the largest of organizations with hundreds of thousands of employees. NSS is a 64-bit file system that can manage a virtually unlimited number of file objects.

On each physical storage device, NSS abstracts up to four physical NetWare partitions to make them appear as contiguous free space. NSS recognizes physical and logical devices up to 2 TB in size from which you can create any number of virtual storage resources, called pools. You can choose space from at least four devices of up to 2 TB each to create a pool with a maximum pool size of 8 TB. A pool can contain an unlimited number of volumes. If the pool spans devices, the volumes automatically span the devices. A single volume can contain up to 8 trillion files and grow to 8 TB in size, depending on the size of the pool and space consumed by other volumes in the pool.

NSS Volumes

The logical volumes you create on NSS storage pools are called NSS volumes. You can specify a maximum storage quota for the volume, or allow the volume to grow dynamically to the size of its pool. You can add any number of volumes to a storage pool.

Because there is no limit to the number of volumes you can create, it is possible that the combined size of all the volumes taken together is larger than the storage pool itself. NSS refers to this process as "overbooking." If you overbook space in the pool, the individual administrative size of a volume cannot exceed the size of the storage pool.

NSS allocates space from the pools to the volumes only as needed. Typically, user consumption of a volume's available space ebbs and flows; it is quite unlikely that users concurrently consume volumes at 100% of their available capacity. Each volume consumes the space it needs as it needs it. By overbooking space, NSS provides a flexible and cost effective way to accommodate expanding storage needs.

How to recover data from crashed NSS Volumes ?
