Postgres as a Service
Deploy a Managed Postgres Cluster in Minutes! Enterprise-ready and Oracle compatible.
3.2.2 The Cluster Members FileEach member of a Failover Manager cluster maintains a cluster members file. The file contains the IP address and port number of the current members of the cluster. The Failover Manager installer creates a file template for the cluster members file named efm.nodes.in in the /etc/efm-2.0 directory. After completing the Failover Manager installation, you must make a working copy of the template.For example, the following command copies the efm.nodes.in file, creating a file named efm.nodes that resides in the same directory:# cp /etc/efm-2.0/efm.nodes.in /etc/efm-2.0/efm.nodesPlease note: By default, Failover Manager expects the cluster members file to be named efm.nodes. If you name the cluster members file something other than efm.nodes, you must modify the service script (efm-2.0) to instruct Failover Manager to use a different name.You are not required to modify the contents of the cluster members file on the first running node of the cluster, but on each subsequent node, you must edit the file, adding the IP address and port number of the other server or servers that are currently members of the cluster. For example, if you are adding a third node to a cluster that contains two members, the file will contain the two addresses and ports of the other nodes:Each node must be listed in an address:port format, separated by white space.Please note: If you know the IP addresses and ports of the nodes that will be joining the cluster, you can include the addresses in the cluster members file at any time. At startup, any addresses that do not identify cluster members are ignored.
• When you start an agent on a new node, the existing agents will update the cluster members files to include the address of the new node.
