For DFSR servers, physical servers give slightly better performance than virtual machines under load conditions since physical servers have dedicated resources and virtual servers are hosted on hypervisors, having other VM workloads, and thus using shared resources.
Microsoft has not provided any special hardware sizing for namespace servers. DFSR Hotfixes. I have not found any lists for Servers yet. DFSR is multi master replication engine. Ideally when deploying DFS Replication:. In hub and spoke topology:. Active Directory replication and name resolution must be working properly. The DFS server polls active directory periodically for updates. This is especially true in case of DFS-R members working in remote sites.
If redundant folder targets need to be added to DFS name space folder to cover multiple locations, make sure that each location has a domain controller installed and AD sites and services are configured appropriately with local subnet mapping to localise resource access.
Because DFSN locates folder targets in the same AD site as the client no matter how you configure target referral ordering. If client subnet is mapped to the wrong site or did not get mapped to any site, DFS namespace referrals will provide the wrong target folder location which can create conflicting changes or if read-only replica gets referred as the folder target.
Source data permissions DFSR. DFSR is not dependent on file system permissions. Refer to the article below for a description of the above rights. If this is a brand new implementation without existing data. The root folder must be set with correct Share and NTFS permissions to avoid access violation issues for users and administrators.
Root folder ownership should be granted to the built-in administrators' group. Grant Full control NTFS permissions to System account and built-in administrators group and remove creator owner group from root folder permissions. If you already have existing data file shares and already facing access issues, refer to my article below to correct those. Windows File Server - Folder ownership problems and resolution.
DFSR uses staging quota to get files staged, calculate its hash and store it in the DFSR database and then sends files to the replicated member. Later on, we can cut down staging quota limit if wanted to. Refer to the link below to calculate approximate staging quotas for a replicated folder. Number of replicated folders per drive. You should consider only one replicated folder per drive, this is useful in case you face any issues like heavy backlog or DFSR database corruption and need to clear out a DFSR database from system volume information.
In this case, if two replicated folders are on the same drive and the issue exists with a single folder, DFSR Database will be wiped out for both folders and both folders would have to undergo initial replication which can take a considerable amount of time if the data size is large. If you are creating replication groups for existing data, or if you are adding a new replicated member to an existing replicated group, and if the data size is bigger in TBs or in few hundred GBs , an initial sync can take a substantial amount of time to complete, due to the complexities involved in initial sync process.
The initial sync must be completed before data can be replicated back and forth and the process can take many days, depending upon the data size being synced. To save time, we can preseed data followed by DFSR database cloning. This process will save time to replicate the data over wire.
However, you still need time for staging as at the DFSR stage, every file is copied with a preseeding and generated a hash of the file and store within the database for initial sync.
This process is local to DFSR member. If a domain DFS namespace and root will be configured, ensure that the account has the necessary permissions to the DFS-Configuration container and child objects in Active Directory.
Select the Namespaces node, and then double-click the Namespaces node to expose the existing namespaces. If the desired namespace does not appear, in the Actions pane, click on the Add Namespaces to Display link and follow the steps to search for and add an existing namespace to the console view. Select the desired existing namespace, and in the Actions pane, click on the Add Namespace Server link. Type in the name of the server, and click OK to continue. If the share already exists, click OK on the pop-up window to use the existing share and existing share permissions.
In the tasks pane, select the Namespace Servers tab to verify that the additional namespace server was successfully added, as shown in Figure3.
Also note that at the top of the pane, it shows that the namespace is a domain-based in Windows Server mode. Figure 3. Verify the successful addition of a namespace server. Windows Server. Subaru Outback. When browsing a folder in the namespace, users are not aware that the folder is hosted by multiple servers. When a user opens the folder, the client computer is automatically referred to a server on its site.
If no same-site servers are available, you can configure the namespace to refer the client to a server that has the lowest connection cost as defined in Active Directory Directory Services AD DS.
Skip to main content. Limitation: Each server can be a member of up to replication groups. Wednesday, May 27, AM. To do so: 1. Start replication. Do not edit any file before initial replication is done. Wednesday, May 20, AM. If you just would like to create replication group without DFS namespace. Thank you. Thursday, May 21, AM.
