0x80070570: The file or directory is corrupted and unreadable.

This is on Server 2012 R2
I have a file that it is stored on a storage pool, space is parity and I'm getting the following error when trying to move/copy/open it:
0x80070570: The file or directory is corrupted and unreadable.
I have run full scan on boot, Repair-Volume cmdlet, SFC.
Nothing can see this file as corrupt except when I try to access it.
How can I repair this file? Isn't parity supposed to prevent this?
The corrupts bits should be able to be repaired if the OS would just recognize it.

Win 2012 R2 - Volume Shadow Copy Service Error

Hello,

I have an issue on a brand new and fresh installed Win 2012 R2 Standard (all updates applied). I get this error when trying to enable shadow copies on one big volume (65 TB spanned volume):

Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{ec8c116f-e1ef-11e4-80c1-44a842035958} - 00000000000001AC,0x0053c008,000000BE7E2E96A0,0,000000BE7E2EA6B0,4096,[0]).  hr = 0x80070057, The parameter is incorrect.
. 

Operation:
   Processing EndPrepareSnapshots

Context:
   Execution Context: System Provider

Chkdsk shows no error. VSS writers are all ok, providers seem ok to me:

Provider name: 'Microsoft File Share Shadow Copy provider'
   Provider type: Fileshare
   Provider Id: {89300202-3cec-4981-9171-19f59559e0f2}
   Version: 1.0.0.1

   Provider type: System
   Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
   Version: 1.0.0.7

I noticed this error when I found Data deduplication was not saving anything. 

Any help will be appreciated.

DFS replication over 70M files - doable?

from https://technet.microsoft.com/en-us/library/cc773238%28v=ws.10%29.aspx#BKMK_00

What are the supported limits of DFS Replication?

The following list provides a set of scalability guidelines that have been tested by Microsoft on Windows Server 2012 R2:

  • Size of all replicated files on a server: 100 terabytes.
  • Number of replicated files on a volume: 70 million.
  • Maximum file size: 250 gigabytes.

We have 150 Million files but size is around 15TB. Anyone used DFS in WIN2012R2 in production? Was it working OK?

    attach vhd access denied - but works in computer management

    I'm running windows server 2008 r2 sp1. When I attach a VHD as read only via Computer Management. It works fine.

    However when I do it via disk part, example:

    select vdisk "vdisk location"
    attach vdisk readonly

    I get an access denied error.

    Whats the difference between attaching it via computer management and attaching it via diskpart?

    I'm trying to automate the process of attaching VHDs, hence why I was trying disk part. Would there be an alternative way?

    I found some threads on here about Windows Search not working on DeDup volumes? Most of the threads are pre-R2 timeframe so I am checking in to see if there is any updated info on if this was fixed in R2? It seems this is a critical feature if you are using a volume for redirected libraries?

    Ricoh Aficio MP C2051 Scan to Folder - Windows Server 2012 Error: Authentication with the destination has failed check settings

    I have recently upgraded a clients servers to Windows Server 2012 & since doing so have lost the ability to scan to folder.

    Both servers are domain controllers and previously on a 2008 domain controller I would have had to make the following change to allow scan to folder:
     Administrative Tools
     Server Manager
     Features
     Group Policy Manager
     Forest: ...
     Default Domain Policy
    Computer configuration
     Policies
     Windows Settings
     Security Settings
     Local Policies
     Security Options
     Microsoft Network Server: Digitally Sign Communications (Always)
     - Define This Policy
     - Disabled

    However I have applied this to the Windows 2012 server but am still unable to scan, possibly due to added layers of security in server 2012. The error on the scanner is Authentication with the destination has failed check settings.
    I have also tried the following at the server:
    Policies -> Security Policies
    Change Network Security: LAN Manager authentication level to: Send LM & NTLM - Use NTLMv2 session security if negotiated.
    Network security: Minimum session security for NTLM SSP based (including secure RPC) clients and uncheck the require 128 bit.
    Network security: Minimum session security for NTLM SSP based (including secure RPC) servers and uncheck the require 128 bit
    I have created a user account on the server for the ricoh and set this in the settiings of the Ricoh and verified everything is correct.

    Are there any other things I have missed?

    Hi everyone.  I've read a lot of posts about Error 5 but all the recommendations haven't worked.  When I run the initial robocopy it works fine, however when I run the same script again the next time, it fails with Error 5 access denied.  I did notice that the use I am using shows permissions in the parent folder as Special Permissions to This Folder Only.  Anyone have any ideas?  I'm using version 6.1.7601 that was downloaded from this site: http://support.microsoft.com/kb/2639043 and the command line: robocopy SOURCE TARGET /MIR /copy:DATSO /B /FFT /R:1 /W:1 /LOG:c:\robocopy\log1.txt

    Hello,

    I recently created an AD new user account that is a member of the Domain Admins and Enterprise Admins groups.  I'm having issues when accessing folder shares on our servers when logged onto servers using this new account.  The folders have the local Administrators group NTFS rights set to Full Control, but when I attempt to open a folder I receive this message: "You don't currently have permissions to access this folder.  Click Continue to permanently get access to this folder." 

    Share permissions are set for Everyone Full Control.

    I have recently discovered that the issue occurs on servers without folder shares too.

    PCIe SSD + Storage Spaces = HUGE read performance drop?

    April 24, 2015, 9:41 pm

    So I'm seeing some strange, slow behavior with a simple Storage Spaces pool with only a pair of mirrored drives.  I've seen lots of folks having problems with SS, but most are issues with parity spaces.

    I've got a new Dell R730xd with 4 of their 400GB nvme ExpresFlash SSDs.  The machine also has a PERC card with a bunch of 15K rpm SAS drives and will be used for SQL Server. (and a pair of E5-2643v3 xeons and 256GB ram)

    This is running Windows Server 2012R2 with all the latest patches.  I've used both Storage Spaces / pools and traditional windows disk management to create a mirrored pair of these drives.  I also tested a single drive by itself.  The SS volume actually showed huge promise for a moment where it was obviously reading simultaneously from both drives.  These are some of the fastest SSDs available now, so these results for just using a pair of them are pretty awesome.  Using the old-school windows disk mirroring does show a performance penalty vs. a bare drive, but it's not drastic, so it's probably what I'll be forced to use unless I can fix the problem.

    *note I later rebuilt this pool using a 4k physical & logical sector size hoping that was the culprit, but it didn't help.  It sorta looks like I'm running into some PCIe bus contention, possibly overloading the backplane. *shrug*

    You can see the PS syntax used to create this here:

    And here's what a single drive looks like by itself:

    Cannot add disk space

    We have a virtual machine server that has a C: (OS), D: (data) partitions. I added unallocated space to the server as the C: (OS) partition is low on disk space. It will not let me add more disk space to the server using disk management.

    The C: and D: partitions are setup as a simple volume on one hard drive. How can I add additional disk space to the server to avoid it potentially crashing.

    Cannot delete network folders - thumbs.db "The action can't be completed because the file is open in Windows Explorer"

    I have applied the GPO user setting "Turn off the caching of thumbnails in hidden thumbs.db files" to every device on my network. It has been applied for weeks.

    When I attempt to delete a folder on another server, that I have full access to and could otherwise delete with no issue, probably 50% of the time I will receive the "The action can't be completed because the file is open in Windows Explorer" message for the thumbds.db.

    Every thread (of the hundreds about this clear 100% bug) says to enable the policy I have to fix this. I have, I've confirmed via gpresult /h and checked the registry key it creates under the user profile. I have no idea how a user policy is meant to stop what I think is the server creating or locking these files, or how with the GPO applied anything should be accessing the thumbs.db.

    I am unsure what steps I can take now to ensure 100% of the time I can delete a network folder. This is such a simple thing I want to do and is stressing me to no end not being able to fix such a simple thing.

    See below. This is from a server where I am trying to delete a folder located on another server. Notice the registry setting is set where it shouldn't be generating (and therefore I assume in anyway locking or accessing) the thumbs.db. I have confirmed and every other client that might touch this folder definitely has this same registry key set.

    Hi, I am planning on setting up DFSR on a lot of branch sites. the plan is to replciate them to the main server in the data centre and backup this serve every night. The data we plan to migrate on the branch servers are home drives etc. What are best practices for doing this? Would I use a read only option on this as I wouldn't want someone to change the data in the data centre and then this replicate back down to the branch server!

    Thanks

    Hello All,

    I am very confused with one of the issue I am dealing with and now I am running out with the ideas so now I need your help to troubleshoot that issue.

    Issue is that I have a single forest but two domains. Both domains have two way trusts etc. I have shared some folders in domain A on windows 2003 server which is perfectly fine on accessing on windows 2003 server on domain B and not asking any credentials but same folders I am trying to access is asking for credentials on windows 2008 r2 server.

    Interesting thing is when I have shared a folder on windows 2008 r2 server its accessing fine on both domains vise versa and on even accessing fine in windows 2003 servers with no credentials requirement.

    So I know for fact that trust relationship of domains and all that are fine.

    What confusing me is that why shared folder on Domain A windows 2003 Server is asking for credentials on Domain B windows 2008 r2 server?

    Please can anyone help on this matter as this is very important and one of the P2 at this moment due to this issue.

    Many Thanks

    Dear All, 

    I am experiencing crisis in the infrastructure 

    I had virus infection and I had recovered from it "not completely" - the problem is folders keeps moving to hidden System volume folder

    I tried working with security essential and it found that I have myfiles.exe infection 

    I blocked all executable files from the system - re installed new OS 

    I still get this problem that folders moved to system volume folder 

    from event viewer - after blocking exe files 

    user UUUUUUU  attempted to save D:\xxx.exe on D:\ on server SSSSS  This file matches the "Executable Files" file group which is not permitted on the system.

    the xxx.exe name is the name of folder which then moved to system volume folder trying to put exe file on its place 

    please advice for urgent remediation

    folder redirection directory change

    hello,

    i am an ict technician at a school in belgium.
    i have a problem with folder redirection, orginaly the folder redirection was configured for SOME of the users f.e:
    my document to \\dc1\homedir\%username%\my documents

    now the following problem , my dc1 storage was not enough to keep up with the place of the documents etc

    2 weeks ago all of my users have folder redirection to \\dc2\homedir\%username%\my documents.
    for the "new users" that didnt used the dc1 before is their no problem but for the users that did use the dc1 is their a problem.
    the sync center doesnt remove the \\dc1 location and gives conflicts.
    the sync center gives the following locations : \\dc1 and \\dc2.
    also when they create a word document and save it under my documents they somethimes get an error, file corrupted or path unfindable. or when they download something it sais u dont have the rights to open while they just downloaded it.
    also somethimes f.e they get no icons on the desktop or on the start menu they are just white icons.

    the only option i know for now is to delete the user profile on the local pc , log in again.
    the user get an temp. account, i log in to my admin again and delete the .bak from the registry
    log in again with the new user and the sync center is allright.
    also theirs no more problem with word or what so ever.
    but this is insane because we have allot of users and allot of pc's its almost impossible to go from pc to pc to remove the users.

    thanks in advance !

    greeting

    I am after a bit of advise about SBSconsole 2008. we have a server that crashed and now in sbs Console whenever I try to add a new user it fails on setting quotas. when I try and edit by double clicking any of the 70 odd exisiting users in sbs console I get error messages.  firstly I get a pop up saying" cannot get quota for shared folder" with a close button then when I close that I get another message saying "the folder redirection quota for the user account cannot be retrieved".  if I right click on the user and edit from there I can edit ok and the changes save and as far as I can tell all the hared folders are working fine and the users can still access I just cannot add any new users.

    any advise I can get would be greatly appreciated

    thanks

    So we are using RDS 2012R2 with well over 100 Personal VMs. The data sits on a Scale Out File Server that is deduplicated. Everything is good except on patch day. I am currently sitting around 45% free with my space but on patch day i dip very low. The more/bigger the patches the closer to 0% i get. It then dedupes out and i am back to the 45% range. What is Microsofts recommendation to handle this huge patch dip?
