DFSR detects dirty shutdown on reboot

August 13, 2014, 10:45 am

Hi all,

I have a Windows 2012 R2 Standard server running DFSR. It is up to date, all hotfixes have been installed, there is no antivirus running on it, and I've tweaked WaitToKillServiceTimeout to 600000. When I do a soft reboot or soft shutdown, when the server comes back up it gives -

"The DFS Replication service has detected an unexpected shutdown on volume F:. This can occur if the service terminated abnormally (due to a power loss, for example) or an error occurred on the volume. The service has automatically initiated a recovery process. The service will rebuild the database if it determines it cannot reliably recover. No user action is required. "

This is happening every time I reboot. Fortunately this server isn't in full production yet, but this issue will need to be resolved before I can put it in production. Does anybody have any suggestion? Thanks in advance.

Scale-Out File Server Interleave Size

August 13, 2014, 3:49 pm

I have a Hyper-V host machine connected to a two-node Scale-Out File Server.

I'm playing around with the Interleave size when creating the Storage Spaces.  Any suggestions for Interleave sizes?  I know the default is 256KB, but I'm wondering if increasing the interleave size (and thus the stripe size) would improve performance for Hyper-V VM performance, especially write performance.  With many of our file servers running as VMs, I'm focused on getting the best file transfer performance as possible from a client to a file server VM.

Thanks.

Extremely weird file share issue

August 8, 2014, 12:48 pm

We are having a very weird issue when trying to access file shares from a remote site. If we use the UNC path (\\servername\sharename\folder) we never have the problem.   Also, if we go to the drive letter and click through the folders, we don't experience the problem.

The problem only arises when pasting the absolute path into windows explorer (ex. L:\foldername\foldername). Once we do that, it hangs for a second and then sends you back to the initial share, and the path in explorer shows <drive letter>\.\.\ (ex. L:\.\.)

As the jpg attached shows. For security rules,  I had to block the share name /server name

I have never seen an issue like this. It only happens from 2 remote offices. Other remote offices are fine

This warning occurred in several seconds after the Windows Server Backup start. Our backup job finishes successfully. That server is in provisioning without a heavy workload, and we have not experienced any problem yet. But we do not want to face any problems due to this error in the production environment.
All disks of the server are managed by the LSI MegaRAID controller, which doesn’t report any errors in the disk system.

it is Windows Server 2012 with the latest updates.

"Failed to set access paths" when trying to mount a partition

I have a newly formatted drive (GPT, NTFS, 64k). When I try to mount it to a folder, I get the error "Failed to set access paths. Failed to add or remove access paths. Invalid Parameter". I have previously mounted drives on this server and they are working fine. I've tried 2 new drives and neither will mount. I have tried in the "Manage Drive Letter and Access Paths" under File and Storage Services. I've also tried the old Disk Management tool and PowerShell.

Can anyone point me in the right direction to fix this issue?

Hi All,

  We have 6 Branch office locations and a centralized Datacenter and DR Site.   File Services which are currently residing in Branch office locations, need to be centralized.

 I like to setup all the users Home Folders and Redirected Folders ( Desktop/MyDocs) to  Production Datacenter and then replicate to DR?

Is  this good idea or what is the recommended or best practice?

I need to remove all the site Backup servers/Tapes/and Offsite storage contract /backup software..

Also i like to have a one MAP drive to access business data in anywhere is these offices.

Again solution must be robust and no disruptions to the business.

You can ask me for any further clarifications on this.

Regards,

  As

Robocopy - exclude destination files from /MIR

Attempting to do a nightly run of robocopy while we transfer over to a new file server. We've a load of extra files with an offline attribute on the destination, which are files archived by Enterprise Vault which we moved in advance, and so these must not be touched.

If I do robocopy source destination /MIR /XA:O, all these files still get deleted. Shouldn't the exclude switch apply to files on the destination as well as the source?

Do I need a server os? Do I need Active Directory?

Hello all! I just moved into a new place and am preparing to setup my network. I have around 2-3 desktops 2-3 laptops, 1 tablet and 1 phone. Then of course there will be guests as well.

I am trying to decide on a couple of things, should I use Windows Server OS or just a normal Windows 7 PC with file-sharing and such set up?

If I use Windows Server should I use Active Directory?

Which would be the better option for Windows Server is I do use it? I have access to Server 2008 and Server 2012. Personally I don't like Windows 8 and from what I understand Server 2012 is similar in its design but if it's really much better I'll learn it.

Sorry for so many questions but this is the first time that I've lived on my own and am able to do anything I want instead of having to worry about parents/room-mates and their PCs.

Thanks in advance!

formatting a volume within disk management causes instability and host crash

We have a 3-node 2012 Cluster that is currently non-production.  We are using MPIO, the default Microsoft DSM, CSVs, Failover Clustering, an EMC VNX5400, and FCoE. 

The LUN is instantly recognized by the Windows Hosts.  Initialization seems to be fine.  Formatting (to create a CSV) causes disk management to freeze and eventually the host will crash.

index $0 for file 25 during every chkdsk

Every time chkdsk runs I get the error index $0 for file 25.  This is a large file server so we really cannot bring the server down often.  A couple weeks ago the power company scheduled a power outage to replace equipment so we brought everything down except this file server.  I connected it to a generator and let the chkdsk run.  It ran for about 5 hours and showed deleting file 25 for about an hour then writing file 25 for about 2 hours then continued to run with no more errors.  After it finished I shut down the server and waited for the power to be restored.  Brought the server online everything seemed fine.  I have been receiving several errors "Ntfs(55) - The file system structure on the disk is corrupt and unusable.  Please run the chkdsk utility on the volume Internal Storage Array.

Trouble with File Auditing events in shared folder

Hi Everybody!

I am trying audit access to a specific folder in a shared folder.

On the machine filesystem auditing has been enabled in like below:

The folder itself has the following permissions ('List folder / read data' is the important one).

This generates event 4663 if the folder is opened from the local machine, this is great.

The problem is, if the folder is opened from a remote machine, no event is logged.

Does anyone know why this could be occurring?  Is there some setting that also needs to be enabled?

Thanks

Administrator Access Denied to Roaming Profile User Folders in Server 2008

We have a Server 2008 domain setup with Roaming Profiles for the users.  I allow Windows to create the folders when the user first logs in.  The Roaming Profiles work great and the users can access their network user folder, but the Administrator does not have access to the user folders.  I get the message "You don't currently have permission to access this folder." when logged in as Administrator and accessing the user folders.  If I look at the folder properties it has "Unable to display current owner." listed as the owner.  I have tried to take ownership of the folder and then give it back to the user, but then the user is unable to access it.  I then have to delete the folder and let Windows recreate it then the user can access it again but not the Administrator.  Administrator has Full Control and is the Owner of the "Users" folder that the users are in. 

So far I have only setup 5 of the 50 users and have not setup a backup yet, but I'm afraid this is going to cause problems with the backup as well.

Thanks for your time!

DFS is not working anymore.

DFS was configured and working fine on Server 2008 STD, but now it's no longer replicating.  Here are some of the errors I am seeing:

---------------------------------------------------------------------------------------
- Due to the following error, the DFS Replication reporting mechanism cannot access the WMI (Windows Management Instrumentation) namespace to retrieve certain reporting information. Error ID: 0x80041002.

- DFS Replication cannot replicate with partner <server name> for replication group <domain>\<name space>\<share>. The partner did not recognize the connection or the replication group configuration. The DFS Replication service used partner DNS name <server name>, IP address <the server ip>, and WINS address<server name> but failed with error ID: 9026 (The connection is invalid). Event ID: 5012

AND

- The DFS Replication service is stopping communication with partner <server name> for replication group Domain System Volume due to an error. The service will retry the connection periodically.
 
Additional Information:
Error: 1726 (The remote procedure call failed.)
Connection ID: 580D7FC3-873F-48CC-AFC1-73E96DFADCE2
Replication Group ID: ACA5FC8A-AA2E-4D40-8ECC-3A0A8F45E5F8
---------------------------------------------------------------------------------------

I also have noticed that there is a disabled sysvol in the replication area which belongs to an decommissioned server.  Not sure if that would mess anything up or not since it is disabled (and not needed), but I can't get rid of it.
