Initiate DFS replication using two local copies of files

August 23, 2009, 5:55 pm

Hi,

I have to manage DFS replication for large folders (40 + GB) on two distant servers connected via a 500 kbps tunnel and I am trying to minimize the replication traffic. After copying the files manually on the target server on temporary folders, I was hoping that the DFS replication engine would be intelligent enough to use the local copy on the target server to avoid having to replicate 40 GB through the low speed VPN tunnel but it just won't work.

I first copied the files on the primary server, create the namespace and replication schedule after having copied copied the same files on a temporary folder on the distant server (copying on the same target folder only seems to cause DFS conflicts).

Also, I also need to add chunks of data sporadically once in a while and I thought it would be easier to send the data via CD first before copying the files to their location on the primary server.

In both cases, I failed to have the target server use the local files instead of copying them from the primary server, hence causing a lot of traffic and congesting the line for days.

How can I force DFS replication to use a local copy of a file (in a separate folder/disk on the target server) instead of copying over all the content through my VPN tunnel?

Thanks.

Work Folders and folder redirection problem if userprofile is "duplicated"

Hi,

I'm doing test for migrating to work folders.

I'm just finding a big problem.

I do exactly what I found in Microsoft documentation, a gpo with folder redirection to %systemdrive%\Users\%Username%\Work folders\Desktop for example

It works great except if the user had a problem with his profile, and the profile is duplicated (like C:\Users\USERNAME.DOMAIN)

I have try to redirect folder to %USERPROFILE%\Work Folders\Desktop instead, but it doesn't work, it seems that as soon as you use %USERPROFILE% in the path, the GPO think you want to use the default folder, even if you have subfolder after...

I can't find any workaround

thanks for your help

Hello,

We have a file server which will be running out of space very soon and we need to find a solution for this.

After analyzing we found that file server have thousands of duplicate files and folders which are consuming unnecessary space which we can free and make some free space.

I would like to know from Microsoft is there any way to find out duplicate files and folders without any software if not which recommended software by Microsoft shall we use to find and delete duplicate files and folders.

Thanks,

Hello, 

I create a virtual hard disk from the data of another virtual hard disk (i.e., I select this option during the new VHD creation wizard). The second virtual hard disk has only one large volume of deduplicated data. Will the newly created virtual hard disk's data be deduplicated as well?

Hi,

I am really confusing on the steps need to take care for migrating dfs server from 2008 r2 to 2012 or 2016 server.

We have around 10 file servers which is in 2008 r2 and management decides to migrate all of these into latest servers.We have 6 root namespace and in each there is again namespaces and too many folders which is redirecting to many file servers and for me its too confusing  where to start with.We will be migrating one by one and we the data's in each server is locally stored and it is too big in size(5 TB each ).

Anyone please help me on this and suggest the best way for DFS migration with detail steps.

I am also searching for a script for finding folder targets which is stored only in a particular server.

Appreciate anybody's response

Regards,

Jini

Mismatch files on two servers

Hello Im sure this has been brought up before but I want to ask for my specific situation.

I started a robocopy process to migrate data from one Domain file server to another different Domain file server. Everything was going as planned and I have done this several times before but unfortunately I had to take a LOA during the process. Upon returning I was notified that apparently some users were allowed to start using the new share before the old one was finalized and taken offline.

So basically we have two servers being used and updated and I need to migrate/combine the two without overwriting and updated files.

I plan to use this command and just wants some eyes to verify this is the correct approach.

Thanks

I map the J: drive with a user that has permissions to the Old file share then run the command from the new File Server.

robocopy "J:\Old Shared "  "E:\NEW Shared" /S /B /E /COPY:DATSOU /XN /XC /R:1 /W:30 /MT:16

or would /XO be better?

What is the relationship between hardware raid stripe element size and windows NTFS allocation unit size? Should both be set with the same number?

The default stripe element size for RAID10 with Dell PERC H740P raid controller is 256KB. How does that work when NTFS C: (OS) allocation unit size is 4KB and NTFS D: (eg. Exchange or SQL) allocation size is 64KB?

Hello, we had our home folders redirected  to one location. we are building new servers and want to change that to a new server. the local logins work fine, the terminal server logins seem to not. they seem to be identical data except for the drive letter itself. do you feel a simple reboot of said servers would be the issue or do you feel that we need to envoke GPO for the termservers to understand whats going on.

Hi all,

We have a 2012 R2 file server, and we would like to give Helpdesk permissions to view open files on that file server, and close them if necessary if someone complains that it is locked.

What is the minimum permissions needed to accomplish this as we do not want to give them Administrator group access.

Client has 2 servers, 2 companies merged....and both Servers are on same Domain.

My issue is that DFS was setup.....and the Data on Server 1 is blowing up the amount of Data on Server 2. The 2 don't share files.

How do I just stop the replication.....I have read many articles....and I dont want an issue of data loss.....I dont need to decommission or kill off DFS....I just need to stop replication.

Is there a proper way to do this without causing a mess.

Accessing a network share on same host PC

Hi there, 

I have a very simple question today

PC-1 has a Shared folder:

  • Folder path:  "d:\Shared" on PC-1
  • Network path: "\\PC-1\Shared"

While network share's main purpose is to have access over the network, what is the difference between the two ways I am accessing that shared folder on host PC-1:

  1. Browsing to the actual local path on PC-1 ( d:\Shared )
  2. Browsing through the network path on PC-1 ( "\\PC-1\Shared" )

in case 2, does it require network to be active?

Another subsidiary question is what is the difference between them:

  1. \\<hostname>\\<anySharedResource>    ( e.g. "\\PC-1\Shared" )
  2. \\<IP-Address>\\<anySharedResource>    ( e.g. "\\192.168.anything.anyhting\Shared" )

Kindly reply

Can Work Folders be accessed as a file share as well?

I am considering deploying work folders.  I want to use it and redirect Documents to it.  I have read articles on how to do this.

We have local workstations and session hosts where we would not want to use work folders.  Instead we would want documents to be located on a file share that contains the work folders.  Thus my question:  Can a sync share and a file share can have the same directories?

Is there a better way to keep work folders off of RDS session hosts?  Yet allow documents to be in a work folder?

Thanks

Folder and subfolder permissions for users

Hello,

Could somebody remind me how to apply permissions to a root folder so the users can create subfolders but other users cannot see them.

Basically:

root folder - all users can access it, anybody can create a folder but only creator sees it.

|- subfolders - users see only those folders that they have permissions, cannot delete subfolders but can delete folder/files inside.

Does it make sense? Maybe there are already tutorials how to do this? I can't seem to find anything.

DFS Replication Issues - Not replicating

August 1, 2019, 7:16 pm

Hello Microsoft Experts, 

We recently had issues that started this week about files not replicating. Honestly, we're not sure when it actually started but was only known Monday this week.

We are using Windows Server 2012 r2 for both sites' File Servers.

Our files are not replicating and upon checking event viewer, we found staging errors. What we did was to increase our staging quota from the default 4096 MB to 50GB, 70GB, and one replicated folder with 100GB. This resolved the errors about staging quota. 

Unfortunately, we're still not getting any files replicated. 

Checking the logs again, we're getting a lot of Event 4412. We're now getting thousands of Event ID 4412 for 3 days (at least from the days we noticed the event ID). Is it cross checking the files in both sites?

Running dfsrdiag backlog shows hundreds of thousands of files in the backlog for several folders. 

Is there nothing else we can do but to wait until they finish? Any way we can set prioritization to these folders with hundreds of thousands of files in the backlog?

iSCSI target not connecting

August 30, 2019, 4:41 am

I am trying to use iSCSI via PowerShell 7 in Windows Server 2019.

Sadly, I can not get the initiator to see the target server.

I have two servers:

  • SRV2 => this is an ISCSI target host. 
  • FS1 => a file server.

The idea is to set up an ISCSI target on SRV2 and to use the initiator on FS1 Eventually FS1 will be clustered with FS2 and the LUN shared between the two.

Here is the script that runs on SRV2 to create the iSCSI target:

Powershell
# Run this on SRV2# 1. Install the iSCSI target feature on SRV2Install-Module-NameWindowsCompatibility-ForceImport-WinModuleServerManagerInstall-WindowsFeatureFS-iSCSITarget-Server-IncludeManagementTools# 2. Explore iSCSI target server settings:Import-WinModule-NameIscsiTargetGet-IscsiTargetServerSetting# 3. Create a folder on SRV1 to hold a iscsi virtual disk$NIHT=@{Path='S:\iSCSI'ItemType='Directory'ErrorAction='SilentlyContinue'}New-Item@NIHT|Out-Null# 4. Create an iSCSI disk (that is a LUN):$LP='S:\iSCSI\SalesData.Vhdx'$LN='SalesTarget'$VDHT=@{Path=$LPDescription='LUN For Sales'SizeBytes=500MB}New-IscsiVirtualDisk@VDHT# 5. Set the iSCSI target, specifiying who can initiate#    an iSCSI connection. $THT=@{TargetName=$LNInitiatorIds='DNSNAME:FS1.Reskit.Org'}New-IscsiServerTarget@THT# 6. Create iSCSI disk target mapping:Add-IscsiVirtualDiskTargetMapping-TargetName$LN-Path$LP## Run remaining on FS1 (iSCSI initiator system)# 7. Adjust the iSCSI service to auto start, then start the service Import-Winmodule-NameIscsiTargetSet-ServiceMSiSCSI-StartupType'Automatic'Start-ServiceMSiSCSI# 8. Setup portal to FS1$PHT=@{TargetPortalAddress='FS1.Reskit.Org'TargetPortalPortNumber=3260}New-IscsiTargetPortal@PHT# 9. Find and view the SalesTarget on portal$Target=Get-IscsiTarget|Where-ObjectNodeAddress-Match'SalesTarget'$Target

Steps 1-7 seem to work just fine. But I never see the iSCSI disk from FS1 on SRV2? Step 9 returns no results.

Clues?

Oh - and for those not familiar, this is PowerShell 7 where we need to use the Windows Compatibility module and import-WinModule. That bit works fine...
