Is it possible to convert thick provisioned to thin provisioned in windows server 2012 R2 Storage Spaces without data loss.

Sir,

I am shifting File server data from FS1 server (Server 2012R2 Std) to FS4 (Server 2016 Std).

In FS1 Server Storage Configuration are as below:

Hard Disk Used: 4TB- 2 Nos. HDD + 1TB-2 Nos. SSD

Provisioning-Fixed

Layout-Mirror

Capacity-4.57 TB

Allocated-4.57 TB

Storage Tiers-Enabled

In FS4 Server Storage Configuration are as below:

Hard Disk Used: 1 TB-6 Nos. SSD

Provisioning-Thin

Layout-Mirror

Capacity-3.5 TB

Allocated-2.71 TB

Storage Tiers-Disable

In FS1, i have created D:\Shares\UsersProfile which saved all thin client users Profile using Folder redirection Policy. but within few months our Storage spaces D drive speed is become very slow which hits its performance. Now Storage Spaces speed is only 50-60 MBps. It may be that i am using the Storage Tiers and HDD.

But in FS4 i am using only SSD and storage space D drive speed is more than 395 MBps.

Now i want to Use only SSD in FS1 Server and remove HDD. 

But in FS1 Server, I am using the Thick Provisioning and Storage Tiers. 

So, i am searching the way to convert the Thick Provisioning to Thin and disable storage Tiers to retires the HDD and finally remove it.

New Hard Drive Missing from Primordial Pool

Hi, Can any of you figure out what might be causing new hard drive (that's recognized by the system) to not appear in the primordial storage pool. Here's what I have and what I've tried:

1. Hard Drive appears in the drive section of Server Manager\File and Storage Services\Volumes\Disks

2. Hard drive is not part of the primordial storage pool

3. Hard drive appears in the Computer Manager > Disk Management as "unallocated"

Here's what I've tried including all variations (sequence of actions, offline/online, formatted, raw, partitioned, etc)

1. Clean disk via the command prompt, powershell and Server Manager GUI.

Crap, I thought I tried more things than this, but I guess going through the different permutations of sequence of actions and formatting following the clean procedure seemed like more. Yes, all I've done is clean the disk every way possible that I could think of without it ever showing up in the primordial pool. 

Details: Windows Server 2016, Up-To-Date, file services and hyperv roles enabled, no domain, single enclosure, not clustered, all drives connected via a single HBA card, tried plugging drive into different points on card, drive tested in another system, drive accessible on computer directly after formatting and creating a volume via disk manager. 

I'm at a loss - any advice will be VERY much welcomed.

File share attributes +rhs??

OK, so I'm moving a file share from one server to another to update to new hardware (actually P2V migration, but pretty much same thing) and came across a weird situation. The folder for the file share was set with the attributes Read Only, Hidden, and System on. This caused all sorts of issues with the robocopy, as you can probably imagine, as a large portion of the subfolders and files also had these attributes. Ever weirder was the that files that wouldn't copy with robocopy were able to seemingly copy using Windows Explorer, but then dropped out of existence shortly afterward. (The drive showed 100GB of free space at 11:00, and then 126GB of free space at midnight.) During my troubleshooting, I turned the attributes off and reran the robocopy, and everything copied over, but too late for my maintenance window.  I think it was actually Windows System File Protection that dropped the files, but I can't be sure. I ended up having to re-enable the old files share and let the users use it for the next week, until I can try again next week. 

My question is: Has anyone here ever heard of a file share intentionally being set to these attributes, and why? I'm at a complete loss on it.

NTFS permissions

Dear all,

I have windows 2012 R2 file server and there is a share which holds user homefolders. The folder is shared and the NTFS permissions look as follows:

CREATOR OWNER - Special permissions
SYSTEM - Full control
Administrators - full control
Users (local) - List folder contents

There are over 500 user folders in this share and they do not have "enable inheritance" enabled. IT staff that are members of domain admins can see and traverse each user homefolder. However, I have a requirement to add a custom security group to the root of the homefolders so they each user folder can be viewed and accessed. 

What is the best way in which I can add this custom security group without affecting each users existing permission on their home folders, given that "enable inheritance" is not enabled.

Hello

What is best practice to achieve an offline fileserver but the app server still needs to write and read from it.
I have 2 separate servers running windows 2012 R2

Somewhat like the diagram below

Network connected drive

Dear,

I am trying to troubleshoot a network folder problem for one of our users. The user is running Windows 10 and as a server we have Windows Server 2008 R2. He didn't have this problem before we upgraded to Windows 10.

On his desktop the user have a shortcut to several drives, all are different folders on the server. One of these drives have a question mark which come up every time he starts the computer. When accessing it, it is saying something along the line that this shortcut is no longer working and would you like to delete the shortcut? He has always clicked no to that question. The interesting thing is that before he clicks on the shortcut the specific drive does not appear in File Explorer but after he has clicked the shortcut and said no to the question, the drive appears in File Explorer and he is able to access his files.

I tried today to use the "net use" command to let him have access but it is not working. It is saying the network drive is not accessible.

I don't know if it is relevant that the drive he is trying to access is in a different OU on the server. But he has all the correct permissions as far as I can see.

Thanks!

HI

I have implemented two node Windows cluster with File server services configured and stand alone File server separately configured as Branch office.(Hyper-V using ISCSI storage)

Referred Article : https://blogs.technet.microsoft.com/filecab/2009/06/29/deploying-dfs-replication-on-a-windows-failover-cluster-part-i/

Node -1 and Node-2 - Cluster nodes

File server service in the cluster : Filecenter

Branch office server - Branch-office.

Issue : I have created replication group and i have used source as Branch office server and destination as a "Filecenter". after configuring this i am able to replicate the folder successfully but vice versa i am not able to do it. I tried to replicate manually but not replication from Filecenter to Branchoffice. I think i am missing something so please guide me.

Configuration Question for HDD Failures

Hi,

on a single 2016 Datacenter Node, with 12x4TB SATA HDD and 4x480GB SSD, how would the storage pool be configured the safest way for fast access and redundancy of a disk ?

At the Moment i have all disks in the pool and manually selected 1 SSD and 2 HDDs as hot spare, in case of a failure, correct ?

What i dont get is, out of my 3 SSDs, i can only select like 100GB of fast performance storage if i create a volume. 100G out of 3x480 ? Are there limits for the cache ?

DFS - Adding Folder Target getting Access Denied

Trying to add a Folder Target (Not a NameSpace) to an existing DFS Root. I'm getting 'Access Denied'. I want to clear, I can access the folder on that server doing a \\... The problem I believe is that I have an existing Folder Target from a server that is long gone. Can that cause 'Access Denied'? I already did a DSFR (Replication) to that server with no problem. I can NOT delete the bad Folder Target or Disable it, I get 'Access Denied'. I have other DFS Roots going to that server with no problems (the other Roots do Not have the bad server listed). 

Or how can I remove a Folder Target that does NOT Exist?

DFS-R Backlog Appears Stuck

January 11, 2017, 10:00 pm

I inherited 2 DFS-R hosts connected via a WAN.  We'll call them Michigan and California.  We have several replication groups, one of which is massive, in the realm of 1.4million files and 1.6 Terabytes after deduplication.  About 2 weeks ago, all of a sudden we had a 1.4 million file back log.  For whatever reason, that backlog jumped back up to 1.4 million at least once since then.  Fast forward to earlier this week and the backlog of files being sent from California to Detroit is ZERO. However, the backlog of files being sent from Detroit to California is seemingly stuck at right around 80,000 and growing (as users continue to make changes).  For the life of me, I can't figure out what's the hold up.  The DFSR logs are pretty much greek to me.  I've seen suggestions to disable membership of the backlogged node, wait for the changes to replicate in AD and get picked up by the member servers, then re-enable it, to kick off an initial sync.  The problem is, I'm under the impression if I do that I'll lose data that hasn't replicated from Detroit to California yet, since California would become the "master".  Sure I can run a preemptive backup, but there's still a chance that someone will change something while that 18 hour backup runs.

Are there any ideas of what I can do.  I'd love to narrow this down to figure out what exactly is the hold up.  I'm at my wit's end with this thing.

Long term, the plan is to replace this current DFS solution with something else or to at least prune it down and/or break it into smaller parts.  However, I'm stuck with what I've got for the moment.

Any help would be GREATLY appreciated.

Storage Spaces Direct - Pooling and Virtual Disk Sizing Recommendations

I will be building a 4 node cluster, each node has 13 1.2TB spindles, and 3 800GB SSD's.

Will be configuring a 3 way mirror across the board.

This results in 62.4 TB of physical capacity and9.6 TB of cache per node

At the moment we use 2TB and 4TB LUN's on our old SAN, does the same sizing apply to CSV's?

My question is what is the best physical sizing for CSV's?

2TB? 4TB? or

Dear All,

I am doing the Cross forest migration Between Domain A and Domain B. So far I created the tust and Exchange Mailboxes have been migrated Successfully . User Profile Migration we cannot do for all users this needs to be carried out in phases.

Now I have a file server, which is in domain A, when I am logged with Domain A profiles i can access the shares

But when I am logges with t he new domain profile i can see the shares getting mapped as i migrated the Group policies objext as well in new domain

but when I try  to access the shares i get access denied

I informed my customer that since we didnt provide the permission on new domain profile its not working

But as per them since its two way trust it should work like this

Please guide me , if i am missing on something or my logic about the permission for new domain account is correct

Does anyone know the process in calling a file from a Win7 client to a windows 2008 r2 server with a Netapp v3240 SAN attached?

January 18, 2017, 8:08 am
$

Hi;

Just wondering if anyone can explain in detail (the steps) how a file gets served to a WIN7 client from a disk on a Fibre-channel Netapp SAN,  through a VMware 5.1 Windows Server 2008 R2 VM, and where it might be slowing down?   Even better, explain the logon process of a Win7 client from pressing enter, through AD authentication, running GPO's which includes setting server drive mappings and pushing a few shortcuts,  and loading the Users roaming profile from the Network.  

The reason I ask is because we have one F/P server VM that is very sluggish, and users can take up to 40 minutes after logging in before they can do anything. Yet, say I move one of their shares to another server, and change the AD profile to point there, the user is ok WRT logon speed.   All of our servers are set up the same, and have roughly the same load.  There are no quotas on their home drives.   The server had been rebuilt from scratch a few months ago, due to the same issues.  The Users on this server are spread-out among many buildings.

Basically, why would it take so long to load?

Thanks.

I have a file sharing server running windows storage server 2008. However, as only 40Gb is allocated for C drive, this disk space is filling up very fast, it has gone down to 10MB before, so I am finding ways to clean up space in C drive.

I understand there is a folder under C:\windows\softwaredistribution\download. Inside download files, there are files that took up nearly 12 GB of my hard disk space, I am wondering if I can delete those files inside this folder?

Thank you
