'Multicast address does not correspond with cluster name' during Cluster Configuration
This article applies to Confluence clustered 5.4 or earlier.
The following error appears in the
Cluster Configuration screen:
Multicast address does not correspond with cluster name. Adding new cluster nodes may fail.
By default, Confluence uses cluster name to generate a random multicast address. In this case, the multicast address and the cluster name are not synchronised.
Verify that the multicast address is synchronised with the cluster name:
- If applicable, stop all cluster nodes except for primary node
In primary node, browse tohttp://path-to-confluence/admin/cluster/hashclustername.jsp
- Enter the previously assigned cluster name e.g.
Compare the generated multicast address with the value inside the primary node's
<confluence-home>/confluence.cfg.xml. They should look like this:
<property name="confluence.cluster.address">22.214.171.124</property> <property name="confluence.cluster.name">atlassian_cluster</property>
- If the details do not match, shutdown the node and edit the
<confluence-home>/confluence.cfg.xmlto reflect the generated values
- If applicable, apply the same changes in other cluster nodes
