VMware Directory Service Replication Can Take a Long
Time
If your environment includes multiple Platform Services Controller instances, and if one of the
Platform Services Controller instances becomes unavailable, your environment continues to function.
When the Platform Services Controller becomes available again, user data and other information are
usually replicated within 60 seconds. In certain special circumstances, however, replication might take a
long time.
Problem
In certain situations, for example, when your environment includes multiple Platform Services Controller
instances in different locations, and you make significant changes while one Platform Services Controller
is unavailable, you do not see replication across VMware Directory Service instances right away. For
example, you do not see a new user that was added to the available Platform Services Controller
instance in the other instance until replication is complete.
Cause
During normal operation, changes to a VMware Directory Service (vmdir) instance in one
Platform Services Controller instance (node) show up in its direct replication partner within about 60
seconds. Depending on the replication topology, changes in one node might have to propagate through
intermediate nodes before they arrive at each vmdir instance in each node. Information that is replicated
includes user information, certificate information, license information for virtual machines that are created,
cloned, or migrated with VMware vMotion, and more.
When the replication link is broken, for example, because of a network outage or because a node
becomes unavailable, changes in the federation do not converge. After the unavailable node is restored,
each node tries to catch up with all changes. Eventually, all vmdir instances converge to a consistent
state but it might take a while to reach that consistent state if many changes occurred while one node was
unavailable.
Solution
Your environment functions normally while replication happens. Do not attempt to solve the problem
unless it persists for over an hour.
Export a Platform Services Controller Support Bundle
You can export a support bundle that contains the log files for the Platform Services Controller services.
After the export, you can explore the logs locally or send the bundle to VMware Support.
Prerequisites
Verify that the Platform Services Controller virtual appliance is successfully deployed and running.
