How to Make a Read Only Cdfs Drive Writable

A read-only replicated folder is a replicated folder on a particular member in which users cannot add together or change files. This is convenient for read-only folders that yous want to keep up-to-appointment with a central server (or servers). For instance, software installation folders, or folders that contain published reports or documents. Read-only replicated folders are as well used by read-only domain controllers (RODCs) to keep the SYSVOL shared folder updated while preventing local changes.

Read-only replicated folders tin can be updated only with content from a read-write member of the replication group. All other attempts to write to the binder volition fail. This includes performing an administrative restore performance using a backup program.

	Warning
	When you brand a replicated folder read-only, DFS Replication overwrites any content on the read-only member that has not yet replicated back to a read-write fellow member. For this reason, it is a good idea to fill-in the folder, create a diagnostic report of replication and check the replication excess before you make a replicated folder that contains existing content read-just.

Making a replicated folder read-only or writeable

• Using the Windows interface
• Using a command line

To make a replicated folder read-only or writeable past using the Windows interface

1. Open up DFS Direction and and then select the appropriate replication group in the panel tree.

   	Of import
   	To use read-only replicated folders, the schema must include the Windows Server 2008 or newer schema additions. To view or manage replication groups that contain read-only replicated folders or members that are failover clusters, you must use the version of DFS Management that is included with Windows Server 2008 R2.

2. On the Memberships tab, right-click the appropriate replicated folder and member and and so click Make read-only, or Make read-write.

To make a replicated folder read-only or writeable by using a command line

• Open up a command prompt window then blazon the following command (to make a read-only binder writeable again, replace /RO:true with /RO:simulated):

  Dfsradmin membership set /RGName:<replication_group> /RFName:<replicated_folder> /MemName:<DOMAIN\Server>/RO:true

Performance Considerations

Read-merely replicated folders can impact the performance of a file server when an existing binder is set to read-just, or if the replicated folder is stored on the same volume as the Windows operating system.

• Changing the read-only or read-write status for a replicated binder causes DFS Replication to perform an initial replication and rebuild the DFS Replication database for the folder. On replicated folders that contain a large number of files, this can slow replication and eat organisation resource until the functioning is complete.
• Storing a read-only replicated folder on the same volume as the Windows installation will result in decreased performance for that volume. The performance decrease occurs primarily when loading the first mini-filter commuter. If at that place are other mini-filter drivers installed, such as an antivirus program or backup programme, the additional functioning subtract of using a read-only replicated folder is small-scale.

  The DFS Replication mini-filter driver intercepts all create and open (IRP_MJ_CREATE) operations for the volume on which the read-just replicated folder is located, and so inspects the destination to see if information technology is located in a read-but replicated folder. If the destination is in a read-only replicated binder, the driver fails the asking to ensure that the binder remains read-but. Inspecting each create and open operation on a volume can impact performance if the read-merely replicated folder is located on the organisation book or any other volume for which there are frequent create or open requests to many dissimilar files.
