File server migration with SMB and NFS from failover cluster to stand alone server

July 3, 2019, 6:53 am

Hello,
I have a question about the migration of fileserver resources within a failover cluster.
Currently I have a failover cluster consisting of 2 windows 2012 storage server nodes.
These nodes are physical.
On this cluster there are 2 file server resources that I would like to move into 2 separate virtual machines with windows server 2012 r2 operating system.
One of these file server resources uses the nfs protocol the other is using SMB.
I use robocopy for the file server resource with SMB and then configure the shares by hand.
The question is:
What is the best procedure to move the nfs file server resource from the cluster to a stand alone server?

Thank you

Hi all,

I have several servers with this issue. It seems that user folders that get transfer to a new servers, or new user creation, will not get a quota applied to their home folder on the server.

Server 2008 R2/2016
Hard Quota
1GB
Warning 85%

It is applied to a few different folders on different servers.
D:\Users\Admins\* --- 1.00 GB Hard (Auto Apply) 
D:\Users\Staff\* --- 1.00 GB Hard (Auto Apply)

The folders say that they match the template. But some users will not show in the FSRM quota screen until the template is refreshed.

I can re-apply the quota manually but what could be causing this issue. 

Thank you

Charles

VSS Snapshots lost after storage outage - event id 14

July 4, 2019, 12:58 am

Hello,

We are currently in a bad design situation where a windows server 2016 (virtual machine, hosted on vmware esxi), as a storage server, access is storage via virtual disk.

This virtual disk is located on a iscsi datastore, mounted on the ESXi. We have 4 vdisks on the VM using this storage.

The iscsi storage array is on a different datacenter than the ESXi (and thus, the windows server).

This is very bad by design but the situation is "like this" and I have to deal with it.

We faced 2 network outage between both datacenters, and each time, all the previous versions of different storage volumes were lost.

First network outage, we lost previous versions on disk 1 and 2, and this second network outage lost previous versions on disk 3 but not other disks.

I think it depends on disk activity at the moment the network outage happens.

Also take not that data volumes have storage space for VSS snapshots on a different volume V: (also hosted on iscsi datastore)

In event log, it looks like this (this time the G: device lost its snapshots) :

First, some warnings about the storage not available :



Then some errors like this :

Also some of these :

And then, the terrible, the horrific, the end of all :

"The shadow copies of volume G: were aborted because of an IO failure on volume V:"

I know this is wrong by design, but I would like to know if I could tweak some values to avoid or at least mitigate this.

Like disk timeouts or whatever. 

Because this will happen again (network outage) but they are always between 1 - 15 min outage, and if I could tell windows to wait a bit longer before considering to erase all snapshots, it would be great !

Thanks for any help :)

Restarting Members of DFS Replication Groups on Server 2016 Standard

Restarting Members of DFS Replication Groups:

Hello Guys, 

I would like to understand Best Practice for restarting members of Replication Groups, and would be delighted for the support, as i am unable to locate this information on Microsofts extensive documents base: https://docs.microsoft.com/en-us/windows-server/storage/dfs-replication/dfsr-overview

We have two Replication Groups configured for sharing their own respective folders, these groups each contain five members of a meshed group. 

What I would like to understand what is the best way to undertake a restart of a member for say a Windows Update (ETA to complete relatively unknown) ?

I have witnessed some mention that shutting down the DFS Replication Service on a member and restarting the server should be sufficient. However, according to this article (If i am understanding correctly: https://www.experts-exchange.com/articles/33297/Microsoft-DFS-Deployment-Considerations-Best-Practises.html) it states:

>For any reason if DFSR replicated folder replication need to be stopped, change replication schedule to No Replication. Do not stop DFSR service. It may leads to DFSR database goes in journal wrap state and take much time to recover.

So am i having to completely stop replication across all groups to restart the member, surely this is overkill?

I have also noticed there to be the option of Disabling the Member but im not completely sure what scenario this is used for.

Any assistance is gratefully received. 

Thanks

Mark

DFS - move countless files within DFS folder

Hi together,

I've to move a lot (!) of files within a DFS replicated folder on a branch office. I'm not sure if DFS is aware of this "move operation" or if DFS will treat the moved files as "new" (and starts replication of all these files once again). Unfortunatly I've found no appropriate best practice guide or similar. So my question is: What is the best possibility to realize that? Is it possible to stop DFSR, move the files on Site A and do the same on Site B right after each other and than resume DFSR? WIll this work? Or will the files will be moved to "ConflictAndDeleted" and replicated again nevertheless.

Thanks for you replies!

Best regards

Audio books image building fails on Windows Server 2019 Core (Hypervizor and VM)

July 4, 2019, 5:47 am

Hi ,

We are migrating from a 2008R2 server to 2019 core standard with Hyper-v role. 2019 Server VM's with GUI.

We burn audio books with files shared from 2008R2. Now I try do the same, from a Virtualized 2019 server.

The PC's (windows 7) that are handeling the cd's burning process can see the shares just fine, but the burning process does not work. The files are .mp3 files, and some files that create the DAISY structure of the CD. The filenames on the CD (The CD's are in DAISY format) are wrong and do not play on Daisy players. I understand that the burning process is our responsibility.

But the process runs fine when the data  resides on a c:\ drive.

- Data shared residing on the c:\ drive of the hypervizor =The process runs fine (premastering of the image to burn)

- Data shared residing on another volume of the hypervizor = We get an error in a log file of the CD burning software "Overflowed directory" or something

-Data shared  residing on a volume of the VM (.vhdx file) = an error

-Data shared  residing on the C:\ drive of the VM = all is fine.

All volumes are NTFS formatted, so are the clients. We also have XP machine's and they run fine after I activated SMB 1 on the servers. But I believe they copy the data to an external FAT32 drive and to the processing from there.

What is even stranger, If I format the VM volumes to FAT32 the process works, but the premastering is extremely slow. ( Very slow on IDE, half as slow on SCSI, on a gen1 VM). When going back to NTFS or ReFS, the shares are fine, but the burning goes wrong.

I'm not asking for a solution for the CD burning process.

But might there be a difference from sharing files from a SMB share on a c:\ drive then from another drive. Or could this be OS' related? The permissions between al drives seem to be the same.  I also think about ISO levels. I'm not an IT pro, but need to get this fixed.

So conclusion, all is fine from sharing files on c:\ drive's, virtualized or not. Any other drive's  do not work. The file sharing is always fine, but the burning process is not.

Thank you for reading this vague issue.

Kind regards,

Hendrik

Hello Community!

Right now I'm facing the Tast that I want to move some dfs shares to a new disk on the same server because the old one is getting to small. The plan is to move all the data to the new disk, disable the dfs share service, change the drive letters so that the new disk has the same drive letter as the old disk, restart the server and with it the dfs service.

The question that I have now is, if I have to do anything else regarding the dfs shares when the new drive has the same drive letter as the old one had?

If so, what are the steps necessary?

Hope you guys can help me out here.

Thank you all!

Hi All:

How are you, I need your help. I have 2 Windows Storage servers, they have 2 NICS interfaces in teaming, using 4 diferent Vlans.

In our plan, Vlan 100 is using for AD authentication, and Vlan 200 for DFS Replication.

It's possible to specific DFS that use Vlan200 for replica and 100 for AD Auth? We have different routes and also hardcode in "hosts" file specifing Hostname and Vlan 200 IPS for the servers, but doesn't work propertly, DFS is trying to use Vlan 100 for traffic and Auth.

How do I grant access to a clustered file server's admin share?

I've set up a clustered file server and would like to grant access to the clustered file server's admin share. From my understanding, admin share permissions can't be modified. Is there any way to grant access to a cluster admin share without adding the user/group to BUILTIN\Administrators. Methods to modify the SMB share fail with "The request is not supported" when applied to an admin share.

ReFS Block Cloning with Data Deduplication Enabled Drive

Hello,

Veeam this year added an experiential feature that allows Veeam to use ReFS Block Cloning on Deduplicated files when the repository is on a 2019 server.

Before I look into enabling this, I wanted to get some clarity into this interoperability between ReFS and Data Deduplication since I can't find much online about this.

From my knowledge I feel having chunked data being written to ReFS that can then be deduplicated and further chunked might cause some problems.

Any insight into this would be helpful, thanks!!

Volume size and Capacity size Don't match

March 3, 2011, 9:28 am

Hello,

I have a fileshare running Windows 2008 R2 that has a Dynamic Disk that is 1670.78 GB formatted NTFS.  The problem is if I look at the properties of the volume it says that the capacity is 987 GB.  I'm not sure how to get the capacity up to the full size of the volume.

The histry is we had a 2003 x64 file share that started life as a scratch place to store files so was RAID 0, according to the original specs for the project that was what they wanted.  After time passed the share became permenant storage and loosing it was actually a problem.  At that point I wanted to make it RAID 5.  However I also was hoping to keep the Shadow Copies to enable them to find previous versions of files so I ended up creating an iSCSI target and mirroring them through windows, which made a full backup including the copies.  I then broke the mirror rebuilt the RAID and then re-mirrored to the new volume.  However becuase of going from RAID 0 to 5 I lost some space so had to resize the volume.  I used a 2008 R2 machine to shring the volume and then raised the capacity back up to the full size.  However the space available never actually grew.

At that point I figured the problem was from the machine still running 2003 R2 and having been touched by a 2008 R2 machine.  So I scheduled an upgrade and the server is now running 2008 R2, however I am still missing 600GB.

I can't expand the Volume at this point since there is no free space on the disk, and if I try to shrink the volume I get the option of how much to shrink, then after saying ok I get the error: "The parameter is incorrect."   When I look in the Application Log I see an error saying the volume wasn't defragmented because an error was encountered. "The parameter is incorrect. (0x80070057)"

Please let me know any suggestions or if there is any additional information that would be helpful.

Thank you,

Eric

"Access limited by Share" - Unable to access files via security group membership

May 29, 2014, 3:45 pm

Greetings,

   I have a weird permissions issue that shouldn't exist. I have a share named "Departments". This share has Domain Admins:FC and Authenticated Users:RW. The folder being shared is also called Departments. The NTFS permissions are Domain Admins:FC and Authenticated Users:RW and inheritance is disabled.

   Under the folder, departments, I have numerous files and folders. I want to restrict access to one folder, Licensing, to a security group labeled "SPLA Tracking". I disable inheritance for this folder, and apply the following permissions: Domain Admins: FC, SPLA Tracking: RW. Seems simple enough. Any member that is part of the SPLA Tracking group will have access to the folder, Licensing. 

Yet, the opposite occurs. No member of the security group is allowed access. If I run the effective access view for this folder directly from the file server, it states that the security group, SPLA Tracking, does not have permissions, "Access limited by Share". 

  No matter what permissions I assign at the share level, Domain Admins:FC and Authenticated users:FC, the same effective permissions is listed for SPLA Tracking. Any clue on why this is occurring?

Domain Users profile folder structure

I'm configuring all the user's profile in AD and having it point to a file server on the network.

What are best practices as far as the folder structure?

\\servername\share$\userprofile 

or

\\servername\share$\users\userprofile

What am getting at is there an advantage to adding another folder like "users" in the second example or can the profiles start at the root of the share like in example 1?

What does Microsoft recommend?

Extremely slow network copy speed

Hello,

We have 2 physical servers.

1st server Windows 2012R2: Intel Xeon E3-1220v3 S1200RP Intel server board, 8G RAM,  LSI megaraid SAS 9271i RAID controller 6x 7.2k 6TB R6, Intel dual NIC XXV710 25g

2nd server Windows 2019: Intel Xeon E5-2620 v4, Foxconn R2-1218R-TH, 16G RAM, LSI megaraid SAS 9271i RAID controller 12x 7.2k 6TB R6, Qlogic QL45212H 25g 

both servers are connected to couple of Cisco Nexus 93180YC-EX via portchannel (VPC).

Problem: When we do the copy of 100+ G file over SMB copy start at 300-400MB than it drops to 50MB and later slowing to 20-30MB per second.

So far we have disabled following (on both sides) in adapter properties: Large send offload ipv4 ipv6, Receive side scaling, TCP checksum offload ipv4 ipv6, virtual machine queues

MTU is set to 9014 (same with default value 1500)

On 2012 we are using intel teaming utility, on 2019 we are using MS team that is bundled in windows. We have several VLANs set on each server. Port speed on switches and i Windows is correct - 25G. Drivers are uptodate. Windows updates no older than 2-3 months.

During the copy CPU usage is ~ 10%, Disk queue on 2012R2 is 0-3, on 2019 0-10 .

No error messages in the logs, no crcs on the ports, no error messages on the switches .. nothing. Just the speed is terribly slow. I don't expect full 25G .... but at last it should be 200-300MB/s.

Any ideas why the copy is so slow?

Thanks

Failed to access Work Folder from Shadow Copy Volume after windows 1803

My Avamar backup failed to access Work Folder in windows 10 (version is 1803. 1809 has the same issue).

Work Folder can be accessed smoothly in normal environment. Only when I create Shadow Copy Volume, backup process(avtar) failed to touch it by following error.

And if I launch backup process in command line, the backup work. The only different of processes for launched user is SYSTEM or administrator.

So looks like process in administrator can access Work Folder from VSS.

process in system can’t access Work Folder from VSS.

VSS path:
\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy11\Users\fuc4\Work Folders
API:
FindFirstFile
GetFileAttributesExW
CreateFileW
Errors:
19 : The media is write protected.

As I know Windows limited some system process to access network.

But for Work Folder, the behavior has never been this before window 1803.

Is there any body know how to resolve this kind of issue?
