Use the guidelines in this section when planning to use DFS to move or split NSS volumes.
Theand tasks are available only for NSS volumes. Both the original and destination volumes are NSS.
The source volume must be an NSS data volume on one of the following server platforms (or later versions):
OES 2 Linux and NetWare
OES 1 SP3 NetWare (DFS is not supported on OES 1 Linux.)
NetWare 6.5 SP6
The destination location for a move or split is a newly created NSS volume on one of the following server platforms (or later versions):
OES 2 Linux and NetWare
OES 1 SP3 NetWare
NetWare 6.5 SP6
The destination NSS volume is typically in a different pool on the same or different server.
You must have unpartitioned free space available for this volume on the destination server. For Linux, the free space must be on an unpartitioned device or on a device that is managed by the Enterprise Volume Management System (EVMS) volume manager.
The destination volume should be configured with the same volume attributes as the original volume. Review the properties for the original volume before you begin a move or split, and note which attributes need to be set. Specifically, the compression attribute must match.
You cannot move the sys: volume on a NetWare server.
Do not split any directories that are part of the default file structure for the sys: volume.
When moving or splitting a volume to a pool on a different server, the administrator username and password must be valid on both servers. Otherwise, theor job fails.
Deleted files are not relocated, so make sure to salvage any deleted files that you want to keep before you begin.
Users can continue to access data on the source volume during the move or split process.
The move or split process tracks which files change after they are copied, so files can be accessed while it is running. The job may reach a point where it is necessary for you to disconnect users in order to allow the job to finish, but not until it has at least attempted to copy all files multiple times.
You cannot move or split to an existing volume. Data is moved or split to the root of a newly created NSS volume that you configure when you define the move or split job.
The original and destination servers must be in the same DFS management context, so you cannot move or split across trees. The DFS management context is necessary even if you are moving the volume to a different pool on the same server.
If a DFS management context does not exist, you must create a DFS management context at an O or OU class level in the Novell eDirectory tree that contains both the source and destination servers. For instructions, see Section 9.1, Creating a DFS Management Context.
The VLDB service must be enabled and running in the DFS management context. For information, see Section 9.4, Starting or Activating the VLDB Service.
NCP Server must be running when you set up the move or split job and remain running until the job is completed.
If you are using CIFS/Samba options for users, make sure that NCP Server is up and running before you define the move or split job. It is not required that CIFS/Samba users be configured as NCP users during or after the move or split is completed.
NCP Server is installed and runs automatically on a NetWare server. On an OES 2 Linux server, NCP Server must be manually installed and configured as an OES service. For information about how to install and configure NCP Server on Linux, see OES 2 SP2: NCP Server for Linux Administration Guide.
Novell Storage Management Services™ (SMS) must be installed and running. On OES 2 Linux, the NetWare Emulation Mode (--tsaMode) for TSAFS must be set to dual when moving NSS volumes from NetWare to Linux. The default setting is linux. For instructions, see Configuring SMS.
For ajob, the trustee access rights for the original volume are transferred automatically to the target volume.
For ajob, only the explicit trustee access rights for the original directory are transferred to the target volume.
Make sure you record the inherited rights for the original directory, then set up the rights on the target volume afterwards so that your users have the appropriate effective rights. For visibility, the users need at least the Read and File Scan rights.
If you use the Novell Distributed File Services Volume Move operation to move a volume that has been upgraded to the new media format for hardlinks, consider the following guidelines:
Before you create the DFS Move Volume job, make sure that NSS is set so that the new target volume is automatically created with the upgraded media format for enhanced hard links. For information and command options, see NW 6.5 SP8: NSS File System Administration Guide.
If you moved the volume without enabling the new media format, you must upgrade the volume to the new media format after the move completes successfully. For information and command options, see NW 6.5 SP8: NSS File System Administration Guide.
In the initial release of OES 2, the Move Volume Wizard does not have an option to enable the Hard Links attribute for the new target volume. After the move is completed and the media format is upgraded for enhanced hard links support, you must manually enable the Hard Links attribute. For instructions, see NW 6.5 SP8: NSS File System Administration Guide.
When moving or splitting volumes in a NetWare cluster, perform the move/split only from an active node and only for unshared volumes. DFS supports Move and Split operations only from one non-clustered volume to another non-clustered volume in a cluster scenario. Move and Split operations between clustered volumes or from a clustered (non-clustered) volume to a non-clustered (clustered) volume do not work. This is true for both NetWare and Linux.
Do not attempt to use theor tasks on a volume that is the primary or secondary storage area in a Novell Dynamic Storage Technology shadow volume.
If the NSS volume is a part of a shadow volume, you must force the data to either the primary or secondary NSS volume in that relationship. After all the data is on a single volume, remove the shadow volume relationship. Then you can move the data on the volume using DFS.
For more information about using DFS with DST, see Section 8.8, Guidelines for Using DFS and Novell Dynamic Storage Technology.
