8 Enter an IP address for the pool.
Each cluster-enabled NSS pool requires its own IP address. The IP address is used to provide
access and failover capability to the cluster-enabled pool (virtual server). The IP address
assigned to the pool remains assigned to the pool regardless of which server in the cluster is
accessing the pool.
9
Select an advertising protocol.
NOTE: The CIFS and AFP check boxes can be checked, but CIFS and AFP functionality does
not apply to Linux. Checking the check boxes has no effect.
You can select or deselect NCP. NCP
TM
is selected by default, and is the protocol used by
Novell clients. Selecting NCP will cause commands to be added to the pool resource load and
unload scripts to activate the NCP protocol on the cluster. This lets you ensure that the cluster-
enabled pool you just created is highly available to Novell clients.
10 (Optional) Check the Online Resource after Create check box.
This causes the NSS volume to automatically mount when the resource is created.
11 Ensure that the Define Additional Properties check box is checked, then click Next and
continue with “Setting Start, Failover, and Failback Modes” on page 42 .
NOTE: Cluster resource load and unload scripts are automatically generated for pools when they
are cluster-enabled.
When the volume resource is brought online, the pool will automatically be activated. You don't
need to activate the pool at the server console.
If you delete a cluster-enabled volume, Novell Cluster Services automatically removes the volume
mount command from the resource load script. If you delete a cluster-enabled pool, Novell Cluster
Services automatically removes the Pool Resource object and the virtual server object from
eDirectory. If you rename a cluster-enabled pool, Novell Cluster Services automatically updates the
pool resource load and unload scripts to reflect the name change. Also, NSS automatically changes
the Pool Resource object name in eDirectory.
3.7.4 Creating Traditional Linux Volumes on Shared Disks
Although you can use the same Linux tools and procedures used to create partitions on local drives
to create Linux file system partitions on shared storage, EVMS is the recommended tool. Using
EVMS to create partitions, volumes, and file systems will help prevent data corruption caused by
multiple nodes accessing the same data. You can create partitions and volumes using any of the
journaled Linux file systems (EXT3, Reiser, etc.). To cluster enable Linux volumes, see
Section 3.7.6, “Cluster Enabling Traditional Linux Volumes on Shared Disks,” on page 36 .
TIP: EVMS virtual volumes are recommended for Novell Cluster Services because they can more
easily be expanded and failed over to different cluster servers than physical devices. You can enter
man evms
at the Linux server console to reference the evms man page, which provides additional
instructions and examples for evms.
You can also enter man mount at the Linux server console to reference the mount man page,
which provides additional instructions and examples for the
mount
command.
