3.7.0 HP StorageWorks HP Scalable NAS File Serving Software administration guide - HP Scalable NAS 3.7 for Linux (AG513-96002, October 2009)
NOTE:
The cluster administrative traffic and the replication traffic should be on separate
interfaces. During high replication load, the administrative traffic may be
overwhelmed if it shares the interface with replication.
• <dest_rootpath> is a PSFS filesystem that will hold the replicas on the destin-
ation cluster.
You can specify only one <dest_ipaddress> and <dest_rootpath> in the file.
All replications directed to the specified IP address are placed under the
<dest_rootpath> on the destination cluster. For example, if /mount1/bar and
/mount2/foo are specified for replication and the <dest_rootpath> is /target,
the replicas will be placed at /target/mount1/bar and /target/mount2/
foo. See Duplicate the source filesystem layout on the destination cluster, below, for
more information.
Each entry is a replication set. The maximum number of replication sets is 200.
Snapshot interval. The time between snapshots. This is also called the replication
interval. The minimum value (and the default) is 120 seconds. If you specify more
than 128 replication sets, the snapshot interval should be increased to 240 seconds
(4 minutes) to avoid excessive replication backlogs.
Sentinel. The nodes on the source cluster that are involved with replication are called
the replication group. One node from the replication group coordinates replication
activities such as performing the file transfers. This node is called the sentinel node.
You can specify in the file which node you would prefer to use for this role.
Following is a example of a completed replication configuration file.
