You can add volumes to the pool later by cluster migrating the pool cluster resource back to the
original server node in the cluster where the pool was created. Otherwise, you get an eDirectory
TM
error because the tools only look for the Pool object under its current server node, and not under the
original node where it it was created.
To create or modify home directories, Distributed File Services junctions, or any other elements that
are managed through eDirectory objects, you must cluster migrate the pool resource back to the
node where it was created before you perform those management tasks. This restriction also applies
to management tasks like renaming a pool or volume that change information in the eDirectory
objects for the shared pool or volume.
D.3 Novell Cluster Services Configuration and
Setup
After configuring NSS mirroring and creating a pool and volume on the mirrored NSS partition, if
you did not cluster-enable the NSS pool on the mirrored partition when you created it, do so by
following the instructions in “
Configuring a Cluster Resource for (Cluster Enabling) an NSS Pool
and Its Volumes ” in the OES 2 SP2: Novell Cluster Services 1.8.5 for NetWare Administration
Guide .
When you cluster-enable a shared disk pool, the commands to start and stop the pool resource are
automatically added to the resource load and unload scripts.
D.4 Checking NSS Volume Mirror Status
After you have configured NSS mirroring with Novell Cluster Services
TM
, you should check to
ensure that it is working properly in a cluster environment.
1
Ensure that the volumes on the cluster-enabled pool are mounted on the assigned server by
entering
volumes
at the server console.
2 Check the mirror status of the mirrored partition by entering
mirror status
at the server
console of the server where the NSS pool on the mirrored partition is active.
After entering
mirror status
, you should see a message indicating that mirror status is 100
percent or a message indicating that the mirrored object is fully synchronized.
3 Migrate the pool to another server in the cluster, and check again to ensure that the volumes on
the pool are mounted by entering
volumes
at the server console.
4 Check the mirror status of the partition again by entering
mirror status
at the server console.
IMPORTANT: If you create or delete a pool or partition on shared storage that is part of a business
continuity cluster, you must run the
cluster scan for new devices
command on a server in
each of the other clusters that belong to the business continuity cluster.
