Hello all
Running Exchange 2013 CU8. Currently we have a 5 node DAG that is stretched across two datacenters. 3 nodes in the primary DC and 2 nodes in the secondary DC. The FSW is located in the primary DC. Because we have three copies of every DB all the databases are configured for circular logging enabled = True. The DAG is configured in an Active\Active mode, meaning we have mounted databases in both datacenters, and we have an unbound namespace model. After activating all the databases in the secondary datacenter and running in this configuration for 24 hours, will the database log files continue to be purged, because i have Circularlogging enabled? If this is true then when it comes time to add the nodes in the primary DC back to the DAG, how will the database copies in the primary DC get up to date with the active copies in the secondary DC? If the database copies in the primary DC are offline, because those nodes are no longer in the DAG, and because Circular logging in enabled, i do not understand how the database copies in the active DC can become up to date?
