Cluster Administration ■ In a clustered deployment, if PCNFS password and group files are being used to provide user and group information, these files must be located on each node of the system. Example: If the password and group files 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 files must be the same on both nodes as well. These password and group files on each server node must be updated periodically to maintain consistency and prevent users or groups from being inadvertently squashed. Non Cluster Aware File Sharing Protocols Services for Macintosh (SFM), File and Print Services for NetWare, HTTP file 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 save 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. Specifically, 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. Creating a New Cluster Group To create a cluster group: 1. Open the WebUI to the Cluster tab and select Cluster Groups. Figure 121: Cluster Groups page 2. Select Create to create a new group. 3. Specify the properties for the new cluster group and select OK to create the cluster group. 218 NAS 4000s and 9000s Administration Guide

Cluster Administration

NAS 4000s and 9000s Administration Guide
In a clustered deployment, if PCNFS password and group files are being used to provide
user and group information, these files must be located on each node of the system.
Example: If the password and group files 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 files must be the
same on both nodes as well.
These password and group files on each server node must be updated periodically to
maintain consistency and prevent users or groups from being inadvertently squashed.
Non Cluster Aware File Sharing Protocols
Services for Macintosh (SFM), File and Print Services for NetWare, HTTP file 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 save 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. Specifically, 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.
Creating a New Cluster Group
To create a cluster group:
1.
Open the WebUI to the
Cluster
tab and select
Cluster Groups
.
Figure 121:
Cluster Groups page
2.
Select
Create
to create a new group.
3.
Specify the properties for the new cluster group and select
OK
to create the cluster group.
