The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
If you open network ports on nodes using the range option, the olcnectl module validate command cannot validate the ports are open. This is due to an issue in the firewall-cmd command. For example, if you use a command like the following which opens ports using a port range:
sudo firewall-cmd --add-port=2379-2380/tcp sudo firewall-cmd --add-port=2379-2380/tcp --permanent
The olcnectl module validate command reports that ports 2379 and 2380 are not open.
Workaround: Open network ports individually, without specifying a port range. For example:
sudo firewall-cmd --add-port=2379/tcp sudo firewall-cmd --add-port=2379/tcp --permanent sudo firewall-cmd --add-port=2380/tcp sudo firewall-cmd --add-port=2380/tcp --permanent
