2012 R2: Create mirror of striped volume

April 14, 2015, 2:20 pm

I'm trying to confirm whether or not the new Storage Manager in 2012 R2 is going to allow us to do uninterrupted storage migrations from one SAN to another.  With Symantec Storage Foundation we are able to present LUNs from the new array, mirror our volumes to the new LUNs, break the "old" mirror off and remove the LUNs from the old array.

At this point it doesn't LOOK like I can do this with Storage Manager.  I have presented 5 test LUNs, created a pool, a virtual disk (5-column stripe), and a volume.  I then presented 5 new LUNs, but I cannot figure out how to create a mirror to these new LUNs.  There just doesn't seem to be an appropriate option for doing this.

Is this possible via cmd tool?

Any ideas are greatly appreciated.

From a Windows 2008 R2 Server,

System error 66 has occurred.

The network resource type is not correct.

c:\> net use * \\<winserver2008>\admin$ 

Drive Z: is now connected to \\<winserver2008\admin$.

However, running the above commands from a Windows 2003 Server, I have no problem at all.

Does anyone has any idea?

Failed Hard Drive, Mirrored Virtual Disk Not Repairing

I am running Server 2012 R2 with Storage Spaces. I have a Storage Pool with 4 drives and 1 virtual disk with all drives in the mirror configuration.

One of the drives recently failed hard and was causing the system to bluescreen. After finding and removing the drive I noticed the Virtual Disk was detached. I tried attaching it with an error. I had a spare drive in the computer that was not in the storage pool so I added it to the storage pool and retied the old failed drive and tried to run a repair all to no luck. For some reason it is not adding the new drive (PhysicalDisk4) to the virtual disk.

I will admit this is my first dealing with a failed drive in Storage Spaces and I'm afraid of loosing data, any help on how to correct the situation would be greatly appreciated.

I've attached pictures of what is happening in Storage Spaces for further info.

No access to shared path (every now and then)

I have a 2008 domain and access several shares from a remote location.

Some of the shares can be accessed as it should be and others cannot.

After rebooting the client it can be just the other way around when accessing these shares.

The shares which cannot be accessed (access denied message) can be accessed when replacing the hostname with it’s ip address. Name resolution is just fine, although you would suspect that is wasn't since it's strange behaviour.

No round robin used so the host is allways accessed the same ip address.

Suspicious aspects are a MS bug or Cisco bug

What’s happening ?

Access Based Enumeration not working Windows 2012 R2 Datacenter

I am having a hard time figuring out why Access Based Enumeration is not working for me.  I have set and re-set the settings and I'm still able to see folders I should not. I do get denied access on folders I don't have access to.  I have checked effective access which say everything is denied to me but I can still see the folder(s) listed. 

I have the share permissions set to authenticated Users - Full Control

I have the NTFS permissions set to the correct Dept. Groups. - Modify, and Domain Admins - Full Control and Guests - Deny Full Control

Any idea's?

--------Update--------

I believe I had found the issue.  It was a rights issue with a group that added to the local admins group.

I've been trying to find a reference for how Dynamic Disks work with MBR an partition style and haven't found one.  Specifically, I want to know how a partitioning style like MBR which allows only four partitions to allow 2000 dynamic disk volumes on it.  Are there such things as primary partitions in this scenario?  Is there a master boot record on any of the volumes?  How does it work? Any help would be appreciated.  Thanks.

Windows 2012 R2 Installer directory grows 20G in 3 months

The installer directory continues to grow without any signs of stopping.  All that is being added are Windows patches and updates.  Is there a way to cleanup old patches?  Is 20G growth normal in such a short time?  Is there a way to troubleshoot this growth if it is not normal?  Most people are complaining if it gets to 2G.  I can't imagine that this is OK.  Is it?  The server was built only 6 months ago.  I know that I can just add memory, but I did that 3 months ago already.

Migrating from Win2012R2 to WIn2008R2 - Local Users and File Permissions

I have a Win2012R2 Workgroup server and the goal is to migrate to a new WIn2008R2 workgroup server

I can´t convert the source .VHD VM to a new .VMDK VM because the target system it´s a ESX 4.1, incompatible with WIN2012R2

I need to migrate files and its permissions AND local users and groups to "replicate" the environment

I can´t convert the .VHD VM to .VMDK beucase the target system it´s a ESX 4.1, incompatible with WIN2012R2

I´m thinking in using firts the server migration tools and after that, migrate files with robocopy or subinacl

Viruses and DFS-R

Hello!

I'm new at working with a  DFS-R environment and I have a come across a problem where my servers won't install updates because of a current virus infection. After some thorough clean up work it seems that I have clean out most of the viruses, however, these servers are file shares configured with DFS-R so I was wondering if the viruses could have been replicated to other DFS-R member servers? Our replication is set to replicate all files across all servers which leads me to think that the viruses have also been replicated? Also I'm new to this company and I've been assigned to deal with this virus issue so any help would be very much appreciated, thanks!!

Recover Files - DFS Deleted

Hi,

Someone in our office ran an incorrect robocopy command which ended up in alot of information being deleted from a DFS.

The changes were made on the source folder which was not up to date with the destination folder so I assume all our missing files and folders are hiding in the Staging folder. I guess first is, is this assumption correct.

Assuming that is correct how can I got about trying to get these files and folders. Unfortunately our Backup to Tape and Previous either have not worked or were too old to capture the changes I need. I cant seem to find what I need in the Conflict and Deleted folder etc etc.

We are running Server 2008.

Cheers,

Zac Avramides

NFS Server: Use 32bit cookies / fileids in Windows 2012R2?

Is it possible to disable 64 bit cookies or enable 32 bit cookies within a Windows 2012 R2 NFS Server?

We are performing a migration, and the current NFS client (solaris 10) is passing back the 64bit fileid / cookie to the application.  Unfortunately the application is 32bit and it promptly fails to see the file.  Upgrading the application isn't an option at this time (as it works on the old linux NFS we are migrating from), so was looking for alternative.

Another alternative is NFS V2, but would rather see what else we could do.

Thanks in Advance

File corruption - possible recovery or repair?

April 21, 2015, 3:48 am

Good morning

We currently have a situation where a user is reporting office files in a folder on a server shared drive are coming up with an error when trying to open them. The error message is as follows:

"Excel cannot open the file -filename- because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."

The problem here is that these files have not been used in quite some time (early 2013), as a result the corruption has gone un-noticed to the point that the furthest back backup of the files we have still has them as corrupt.

I have tried several suggested methods of trying to open these files up, these are as follows:

-Try using a third party repair tool to fix the corruption within the files

-Use the windows explorer 'open and repair' feature and try to open the files

-Open the corrupt files up using open source (openoffice, Libre office .etc) office software

-Use a file converter to try switching the format of the file (in this case .XLSX to .XLS)

So far none of these above methods have worked. Is there any hope of getting these files back?

Add domain controller from subdomain to as DFS Namespace Server.

Is it possible to add a domain controller from another domain to the same namespace? I have a forest with subdomains. I wanted to replicate the DFS Tree to a DC closer to users just to reduce the number of hops.   I don't want to have to add a server from our root domain to the site.

If I can't add the DC to the existing namespace can I create the same namespace in a subdomain?

When I try all I get is an error completely devoid of information.

SharePoint Foundation 2010 - StoreMan.aspx page not reporting proper metrics

April 21, 2015, 7:40 am

The configuration of my farm:

Sharepoint 2010 Foundation - up to date on all service packs.

SharePoint Offers an Application Page (_layouts/storman.aspx) which enables the user to view the Size usage of files throughout a Site collection. 

Currently this page is only referred from within the Site settings. Only those with owner rights can get to the link.  We are planning to set  up the link on an "Admin Dashboard page" so all users can see and use the information to delete versions or uneeded documents. It's very handy for this type of reporting.

The problem is that the numbers shown in the .aspx page do not properly reflect the values shown in the libraries. I'm sure the timer job that runs this report is looking at all versions throughout the portal (even in the recycle bin). This is where I see the innacuracy I'm experiencing.  Is there a way to get Storageman.aspx to only run on the files in libraries and ignore the recycle bin? Does anyone have any ideas of how to give users more accurate data on file sizes? Our storage is locally hosted and we adhere to a strict data usage policy, yet I'm finding it difficult to enforce without the ability to show users where the "problem children" live.

NFSv4.0 client for Windows servers?

Does anyone know if there is an NFSv4.0 client that I can install on my Windows servers (2008 and 2012) to access a file system that supports the NFSv4.0 protocol?

I tried the native Windows "Client for NFS" but it appears to be using NFSv3 (client uses v3 MOUNT commands). I also tried a client from UMichigan, but it only supports v4.1 (separate protocol).

Would really appreciate your help!

This is our scenario.  We have a Virtual Machine running on ESXi5.5/6.  There is a VMDK virtual disk presented to this VM that is used for a file server data disk.  The volume is formatted with the ReFS file system.  Storage spaces is not being used. 

In this scenario does ReFS automatically detect any corruption to the file system?
