        14.  
          Continuous replication configuration may fail if the continuous replication IP is not online on the master node but is online on another node
        15.  
          If you restart any node in the primary or the secondary cluster, replication may go into a PAUSED state

Latest directory content of server is not visible to the client if time is not synchronized across the nodes

If the share is updated from multiple nodes, the actual server directory content may not be immediately visible on the client and will take some time. The cache invalidation of directory content is based on the modification time of the directory. Since the time is not in synchronized on the nodes of the cluster, this cache invalidation displays.

Workaround:

Configure NTP on the server to synchronize the time of all the nodes.
