Automated backups are failing for no obvious reason.
Validate that both IP addresses on the Service Instance VM are reachable. Also, compare the Service Instance VM uptime with the uptime of the
systemd-networkd service running on the VM. If both IP addresses are not reachable and the VM uptime is considerably greater than the service uptime, the
systemd-networkd service was likely restarted after VM boot.
The Provider VM and Service Instance VM each have two network interfaces. eth0 must be the VM's default gateway. Source-based routing is required for eth1.
Routing rules are removed when the
systemd-networkd service is restarted. Data Management for VMware Tanzu takes care of configuring source-based routing during the VM's boot. However, DMS cannot detect a
systemd-networkd service restart that is initiated after the VM is booted. If the service happens to be restarted after boot, you must manually run a script to re-configure source-based routing.
Log in to the Service Instance VM as the
Manually run the DMS script that configures source-based routing:
Validate that automated backups return to functioning normally.
There is no impact on Service Instance uptime, nor on a client's ability to connect to a database.
