Hi,

I have a partition have about 116GB used space i can see that in the partition properties, but i can't see any file in this partition, i have choose display the hidden files option, somebody meet the same issue? i am useing 2012r2.

Hello,

I have recently setup 2 dfsn & dfsr servers, both 2012 one physical the other virtual.

The idea is to have one server as primary and the other as a failover \ DR.

The primary server is virtual and connects via mpio \ iscsi to a dell san, using the provided dell DSM Drivers.

The secondary server is physical with local disk for storage.

I copy files to a namespace setup to always prefer the primary server, these files are then replicated across to the secondary.

I have also turned on deduplication on both servers to get the most out of the available storage.

This has been working well for 6 months or so, there have however been 2-3 occasions where the primary virtual server has crashed and blue screened causing the DFSR database to undergo a full consistency check.

The bug check errors i have managed to extract from the Memory.dmp and mini dump are as follows:

REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: fffffa80379a3070, Object whose reference count is being lowered
Arg3: 0000000000000002, Reserved
Arg4: ffffffffffffffff, Reserved
    The reference count of an object is illegal for the current state of the object.
    Each time a driver uses a pointer to an object the driver calls a kernel routine
    to increment the reference count of the object. When the driver is done with the
    pointer the driver calls another kernel routine to decrement the reference count.
    Drivers must match calls to the increment and decrement routines. This bugcheck
    can occur because an object's reference count goes to zero while there are still
    open handles to the object, in which case the fourth parameter indicates the number
    of opened handles. It may also occur when the object?s reference count drops below zero
    whether or not there are open handles to the object, and in that case the fourth parameter
    contains the actual value of the pointer references count.

I have searched for others having a similar problem but have not managed to find much.

The memory dump at the time of the crash does seem to hint at a problem with DFSR.exe.

The setup seems to be running fine again now and is going through its consistency checks, it is just a major inconvenience and will only get worse as the DFS becomes busier and approaches capacity.

The plan was to put this setup into production however with the unpredictability of blue screen reboots I cannot see this happening until I can find a fix or work around.

I have yet to see this problem occur on the other (physical) server, this is pretty much identical in configuration apart from its storage access.

My thoughts are a possible bug in the DFSR component or a bug in the DSM Drivers used for the iSCSI SAN connection or maybe a combination of the two.

Any help, thoughts or suggestions greatly appreciated

Thanks

I am moving from a traditional File Server with Mapped Drives to DFS on a Windows Server 2012 R2. I created 2 namespaces with Folders below the Namespaces. I did move a folder from old server to the folder in the namespace and when I tried to add the folder it gives me an error that "The File Exists".

I moved the folder out of the namespace, still will not let me add 8 hours later. I decided to rename the folder to see if that helped but same error.

Why can I not created folder under namespace even though I moved and renamed the folder?

I am looking for ideas here.

We have a 2012 r2 file server that has a share with Access Based Enumeration turned on. This has been going on forever, what happens is if around 6 or more people try to open a folder at the same time it can hang for up to a few minutes. We troubleshooted this problem forever before testing turning off the Access Based Enumeration and boom problem all fixed.

Ideas on why this is an issue? We really really want to use ABE.

Hi All,

We have Work Folders successfully set up on our domain. A non domain joined client can connect and gain access to their work folder share without issue.

I am now in the process of setting up domain connected laptops that will be used by staff. These laptop will have restrictions on them and the users that logon will not have admin privileges.

The work folder server has the device policies of:

• Encrypt Work Folders
• Automatically lock screen, and require a password

We are using Windows 8.1 enterprise clients, with the latest patches. If I turn off the "Automatically lock screen...." policy, a domain user can successfully sync their work. If I turn it back on they get the below error:

"Make sure that your account is an administrator on the PC and that all administrator accounts on this PC have a password."

I have set the group polices that I believe might effect this message, but have yet to get a successful sync. Could someone give me the exact group policies I would need to set for client to meet the security requirements.

• Minimum password length of 6
• Autolock screen set to be 15 minutes or less
• Maximum password retry of 10 or less

If I disabled the path marked as "active/optimized", then the other path "active/unoptimized" will take over....but wehn both are enabled, only the "active/optimized" path is used.

How can I change the path setting of the "active/unoptimized" to "active/optimized"? I've alreday tried to change it via disk management->properties->mpio, but wehn I want to apply the settings I get an error message:

Hello,

I have been trying to get the command tab in FSRM to work with no luck. I tried to follow the other suggestion I found online still does not work. Not sure what I'm doing wrong here. I can't get the script to run. I'm testing this on server 2012 R2.

Hi All,

we are facing a wired issue that if a user tries to share a folder in a PC (already a local admin of the PC or domain admin) prompts for the domain password to search the users from domain.

anybody gone through this?

thanks.

We are using Server 2008 with FSRM 6.1 and are randomly seeing some quotas reporting incorrectly that they are at 100%. If the folder is checked they are well under the quota but FRSM still reports it as 100% even after a refresh.

The only way that I have seen the quotas reporting as normal is when we delete them and recreate them but it returns a few weeks later.

This is only happening on one file server (we have several that FRSM manages the quota allocations for) and disk compression has not been turned on for that volume. This also is not happening to every quota on that volume, only some.

Any ideas?

I understand that 8.3 file naming should be disabled when using DFSR, especially with read-only replicas.  And, in general, it's good practice for performance.

BUT, is it really necessary?  I understand it could cause some the outgoing replication folder on a RO DFSR replica may occur, but is this really a problem?  Aside from cosmetic and the fact that it takes up space...

I ask because it's enabled on all my servers, and I'm paraoid that if I enable it, it will cause some programs issues  as we use a ton of different software packages for engineering, and some are quite old....

I have a storage pool made up from 7 physical desktop drives all attached to the motherboard SATA ports.

Seagate 4TB (x4)
Western Digital 2TB (x1)
Western Digital 500GB (x2)
Pool size: 17.3TB (as repored by Win)

The problem seems to be with Thin disks, they use up free pool space when i copy files to the virtual disk but when i delete the files only part of the allocated space is returned. To test this out more thoroughly i created a new "2-Way Mirror Thin ReFS" disk and copied about 650GB to it, waited until next day, and promptly deleted it all. The virtual disk was now empty, yet it still allocated about 680GB from the pool which would not be returned until the virtual disk itself was deleted.

My largest virtual storage disk (2-Way Mirror Thin ReFS) now has 2TB+ "Ghost" allocation that it refuses to return to the pool and it keeps growing whenever i make any changes. The data on this virtual disk exceeds my other free disk space elsewhere so i cant move all the data off it and recreate it. I need to fix it on the fly somehow and preferably without buying a ton of new diskspace.

I tried Optimize-Volume as suggested on a bunch of google search results with the following result:

If I disabled the path marked as "active/optimized", then the other path "active/unoptimized" will take over....but wehn both are enabled, only the "active/optimized" path is used.

How can I change the path setting of the "active/unoptimized" to "active/optimized"? I've alreday tried to change it via disk management->properties->mpio, but wehn I want to apply the settings I get an error message:

Hi ...,

I have a Gluster 3.4 Storage which I am trying to mount on a Windows 7 client using NFS.
I am able to do this perfectly without any issues on a Linux Client.

The issue that I face is  -
It mounts the NFS Share, but doesn't show any files / directories in it.
It also doesn't show any storage capacity / utilization below the drive icon. It just shows 'NFS'.
However, if I mount it using '-o anon' option, it mounts perfectly and show all files and directories correctly.
(Anonymous mounts cannot be used in the production environment)

So it looks like an authentication issue.

I have Unix Attributes enabled on the ADS server. The Linux clients use the ADS IDs for its authentication.
I have configured 'Services for Network File System' to use this ADS authentication.

Any ideas as to what could be wrong?

Thanks and Regards,

Can share, server administrator access, or NTFS permissions that are granted to a computer or resource be time based so that access is denied after a defined date or removed using any server or product within the Microsoft suite?  

I know there are products out there to control administrator groups access I've also reviewed the dynamic access control with claims.  I'd really prefer to stick within the Microsoft suite and I don't see these specific senarios discussed so far.  I'm open to other options of accomplishing the task too with other Microsoft components (system center etc.).  

Can this be done?  Has anyone done this level of security control with only MS products before and I'm not hitting the specific search term in bing/google?

Thanks,

Jeff

Hi,

Previously, all PC can access to clustered server by "\\NAS".

But today Windows 2000 users can't, they can access with IP address or "\\NAS.ms.com.hk" only with error "Logon Failure: The target account name is incorrect"

Please help !!

Thanks

I have 5 sites to manage and need to create replicated folders using a domain DFS on at least one server on each site. (2008R2)

My aim is to work out the most efficient (i.e. least work) of creating shares on each server and ensuring that permissions are consistent.

At the start there will notionally be one "master" share and all the other "satellite" servers will connect bi-directionally with this central one.

So if I ensure that when the folders are created on the satellite servers that administrators and system have NTFS full control, will those folders inherit the permissions from the source folder, or will I need to set permissions on each server?

User is using Windows 7 in networked environment and originally used a UNC path to a Windows 2008 R2 Server (Running in Veeam with a drive shared from the SAN).

From within the zipped folder containing about 10 small files selecting about 6 files and then copy

Then navigating back up out of the zip folder to a couple of folders above and pasting

On some occassions nothing happens

On other occassions one or perhaps two of the files appear. (When doing the same logged into the server this works as it should)

Pasting results to desktop, all the files appear, then moving the file back to original folder works without a problem and is currently in use as a workaround, but users want this resolved as it is a pain for them to use the workaround.

Infrastsructure Guru (IG) suggested mapping a drive instead of using a UNC path. I tried this myself initially mapping the z: drive but it still failed. IG then suggested I map it as o: instead as that is what he had done and it seemed to work. I did this and it seemed to work for me. I then did the same for the user but this also failed.

The procedure used to copy and paste out of the zip folder has worked for a long time, until we recently moved the whole application to this newly built server it started giving these problems

Also happen to note that right clicking inside any folder on the o: drive and clicking new folder, it takes quite a while for the new folder to appear. In some cases I have to refresh Explorer to show the new folder. (Might be related)

Since I started typing this message, I have followed some links on technet and found the following instructions which I tried on the Windows 7 Machine and this seems to resolve the problem.

sc config lanmanworkstation depend= bowser/mrxsmb10/nsi
sc config mrxsmb20 start= disabled

However support.microsoft.com/kb/2696547/en-gb suggests not to disable smb2 and only do this for testing purposes.
 
So now that I have done testing and confirm it resolves the issue, what am I mean to do?

BTW, I also tried following these instructions
Start -> Control Panel -> Programs -> Turn Windows Features on or off -> Uncheck the box "Remote Differential Compression"
but after {Turn Windows Features on or off} I ended up in the task scheduler and could not find a box to uncheck for "Remote Differential Compression"

Any help will be greatly appreciated
