      3. You can perform a force failover when the source server is healthy.
      4. After performing a failover, you can perform a re-­protect action to sync data on two servers again.
      5. When performing a re­-protect action, you can choose either of the servers to sync data from and choose the new source server for the replication task.

    • Both Synology NAS devices must have identical MailPlus application portal and privilege settings to ensure stability when switching load balancing services from one server to the other for MailPlus Server.
    • To upgrade the MailPlus Server in active­-active mode from Beta 1/Beta 2 version to the official version, it is required to remove the cluster mechanism first and upgrade two nodes separately. After the upgrade, set up the active-­active cluster with two nodes again and the data will be synced automatically. Such initiative will not be required after DSM 6.0.

Known Issues & Limitations

  1. For locally modified files in a read­-only sync folder, the status will always be "syncing" in DS cloud.
  2. Re-­enabling indexing services previously set will be required when you upgrading DSM 6.0.
  3. Upgrade to DSM 6.0 will trigger media indexing for Audio Station browsing enhancement.
  4. Because of structure change, some notifications that occurred before the upgrade could abnormally displayed. All notifications generated after upgrading to DSM 6.0 will be shown normally.
  5. MailPlus and MailPlus Server:
    • Initial retrieval of mail using the POP3 fetch function may take longer than usual.
    • MailPlus Server is required to be configured before running MailPlus.
    • MailPlus is required to be installed on both Synology NAS devices to ensure stability when switching load balancing services from one server to the other for MailPlus Server.
    • Both Synology NAS devices must have identical MailPlus application portal and privilege settings to ensure stability when switching load balancing services from one server to the other for MailPlus Server.
    • To upgrade the MailPlus Server in active­-active mode from Beta 1/Beta 2 version to the official version, it is required to remove the cluster mechanism first and upgrade two nodes separately. After the upgrade, set up the active-­active cluster with two nodes again and the data will be synced automatically. Such initiative will not be required after DSM 6.0.
  6. The function to customize library visibility will not be applied to DS video in the following mobile platforms: iOS, Windows Phone, Roku TV, and Samsung TV.
  7. After converting the permission type to ACL, the settings in Photo Station and File Station may still be inconsistent. For better user experience, the shared folder "photo" will be converted automatically back to Linux mode if you have done the ACL conversion in DSM 6.0 RC.
