If NFS administration tasks are performed on a computer that belongs to a domain that is not
trusted by the domain of the cluster, the changes are not properly replicated among the nodes in
the cluster.
•
In a clustered deployment, if PCNFS password and group
fi
les are being used to provide user and
group information, these
fi
les must be located on each node of the system.
Example: If the password and group
fi
les are located at
c:\maps
on node 1, then they must also
be at
c:\maps
on node 2. The contents of the password and group
fi
les must be the same on
both nodes as well.
These password and group
fi
les on each server node must be updated periodically to maintain
consistency and prevent users or groups from being inadvertently squashed.
Non cluster aware
fi
le sharing protocols
Services for Macintosh (SFM), File and Print Services for NetWare, HTTP
fi
le sharing protocols are not
cluster aware and will experience service interruption if installed on a clustered resource during failover
events of the resource. Service interruptions will be similar to those experienced during a server outage.
Data that has not been saved to disk prior to the outage will experience data loss. In the case of SFM,
it is not supported because SFM maintains state information in memory. Speci
fi
cally, the Macintosh
volume index is located in paged pool memory. Using SFM in clustered mode is not supported and
may result in data loss similar in nature to a downed server should the resource it is based on fails
over to the opposing node.
Adding new storage to a cluster
Present the new storage to one node in the cluster. This can be accomplished through selective storage
presentation or through SAN switch zoning.
The tasks described below are used to add storage to a cluster. Refer to the online help for clustering
for additional details.
Creating physical disk resources
A physical disk resource must reside within a cluster group. An existing cluster group can be used or a
new cluster group must be created. For information on creating disk resources, see the cluster online
help topic
Physical Disk resource type
.
NOTE:
•
Physical disk resources usually do not have any dependencies set.
•
In multi-node clusters it is necessary to specify the node to move the group to. When a cluster group
is moved to another node, all resources in that group are moved.
•
When a physical disk resource is owned by a node, the disk appears as an unknown, unreadable
disk to all other cluster nodes. This is a normal condition. When the physical disk resource moves to
another node, the disk resource then becomes readable.
