NSS provides the following enhancements and changes in OES 2015:
Two Pool Types: Beginning with OES 2015, NSS supports two pool types:
|
Pool Type |
Maximum Pool Size |
Supported OES Versions |
|---|---|---|
|
NSS32 (32-bit) |
8 Terabytes (TB) |
OES 2015 and earlier |
|
NSS64 (64-bit) |
8 Exabytes (EB) |
OES 2015 only |
Pool Type Cannot Be Changed: The NSS pool type (NSS32 or NSS64) is specified upon creation and cannot be changed.
32-bit and 64-bit Volumes Cannot Coexist: A pool cannot contain both NSS 32-bit and 64-bit volumes. However, NSS32 and NSS64 bit Pool type can coexist on the same server or on a cluster.
Copying of files between volumes of different types and all other pool to pool and volume to volume interactions are supported.
Pre-OES 2015 Servers Cannot Access NSS64 and NSS32 AD-Enabled Pools: If you have mixed-node clusters, keep in mind that pre-OES 2015 servers cannot provide failover access to NSS64 and NSS32 pools that are enabled for NSS AD integration support (nor the volumes they contain) because of the media change required. This includes the following:
Media-Upgraded NSS32 pools and associated volumes
All NSS64 pools and associated volumes
Migrating NSS Data from 32-bit to 64-bit: The NSS data is migrated from NSS32 to NSS64 using different methods. For more information, see Migrating NSS Data from NSS32 to NSS64 in the OES 2015 SP1: NSS File System Administration Guide for Linux.
Tool Support for 8 EB Pools and Volumes: All of the NSS management utilities and tools have been updated to support 8 EB pools and volumes, including:
NLVM: Support for creating NSS32 and NSS64 NSS pools has been added.
For more information, see What’s New or Changed in Novell Linux Volume Manager
in the OES 2015 SP1: NLVM Reference.
nsscon: The PoolMediaVersion command is enhanced to list the pool type (NSS32 or NSS64) for all active NSS pools that are currently associated with a server.
For more information, see nsscon
and NSS Commands
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nssmu: Pool type (NSS32 or NSS64) support has been added as follows:
Pool type information is displayed on the Pools page.
The pool type must be specified when creating a new pool using nssmu.
For more information, see the NSS Management Utility (NSSMU) Quick Reference
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
iManager > Storage Plug-in: Pool type information is integrated with the plug-in as follows:
Pool type information is displayed on the Pools page.
The pool type must be specified when creating a new pool using the Storage plug-in.
For more information, see the Managing NSS Pools
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
IMPORTANT:In all cases, volumes must be AD-enabled to support AD users. Having pool media that supports AD trustee ACLs is a prerequisite to volume enabling, but media support and AD-enabling volumes are two separate things. Both must be in place for NSS AD support to work.
Beginning with OES 2015, authenticated Active Directory (AD) users can natively access NSS resources using a CIFS client, such as Windows Explorer.
For more information, see NSS Active Directory Support
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
The following points summarize the AD-support changes in OES 2015 and provide links to more information:
Media Change Required: NSS file system support for inserting AD user trustee assignments requires an NSS media change.
For more information, see NSS Media Upgrade
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
Enabling NSS-AD Support: To prepare NSS pools for AD support, you have three options:
Upgrade Existing Pools: Using either nsscon, nssmu, or the iManager Storage plug-in.
Enable while Creating New NSS32 Pools: Using either nsscon, nssmu, or the iManager Storage plug-in.
Create New NSS64 Pools: AD trustee support is built in.
Limiting Access for AD Users: To limit NSS resource access to only specific AD users, create a universal group with the sAMAccountName OESAccessGrp anywhere in the AD forest.
Tools Support Changes: To support NSS-AD integration, the NSS team has enhanced existing tools and created new tools, as follows:
Novell File Access Rights Management (NFARM) (New): Provides AD administrators and users with Novell-Client-like management of NSS.
For more information, see OES File Access Rights Management (NFARM)
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
Novell User Rights Map (NURM) (New): Lets you migrate the NSS trustee assignments of eDirectory users and groups to their matching user and group accounts in Active Directory.
For more information, seeOES User Rights Management (NURM)
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nsschown (Enhanced): Options are added for changing file and directory ownership based on the owner’s Security Identifier (SID) or AD Username. There is also an option to change the ownership of extended attributes at the same time.
For more information, see nsschown
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nsscon (Enhanced): Commands are added for the following:
Updating NSS media for AD support
Enabling and disabling automatic AD support on newly created volumes
Forcing an AD support upgrade in a mixed-node cluster
Toggling fast updates of messy files on and off
For more information, see NSS Media Upgrade Commands
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
rights (Enhanced): Options are added for managing rights for AD users and groups.
For more information, see rights
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nssquota (Enhanced): Options are added for setting quotas for AD users and groups.
For more information, see nssquota
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nssmu (Enhanced): Options are added for the following:
Specifying the pool type when creating a new pool
Joining a clustered pool to an AD domain
Upgrading the media on existing pools and volumes for AD support
For more information, see nssmu
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
iManager Plug-ins (Enhanced): The following capabilities have been added to iManager Storage plug-ins:
Pool Type: Creating NSS 64-bit pools and volumes.
AD media: Support for creating, upgrading, and enabling pools and volumes to support AD users.
nsssettings (New): Displays the settings of active NSS pools and volumes.
See nsssettings
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
nssmu shortcut options: New shortcut options are added to invoke various NSSMU functionalities in popular SSH clients, like PuTTY.
For more information, see NSS Management Utility (NSSMU) Quick Reference
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
Hard Link Media Upgrade: All volumes created or migrated to OES 2015 are automatically hard link media upgraded.
For more information, see Automatic Hard Link Media Upgrade
in the OES 2015 SP1: NSS File System Administration Guide for Linux.
Hard Link Media Upgrade Commands: Because all volumes on OES 2015 servers are automatically hard-link media upgraded, the hard link media upgrade commands /ZLSSUpgradeCurrentVolumeMediaFormat and /ZLSSUpgradeNewVolumeMediaFormat have been removed from OES beginning with OES 2015.
