Windows Server 2016 Storage Spaces Tier ReFS
Tier optimization task of ReFS volume is not working in Windows Server 2016.
> Get-Volume g |Optimize-Volume -TierOptimize
Optimize-Volume : The volume optimization operation requested is not supported by the hardware backing the volume.
Activity ID: {3dbe8d23-3259-49ff-a3ec-e7f16eff301b}
+ CategoryInfo : NotSpecified: (StorageWMI:ROOT/Microsoft/...age/MSFT_Volume) [Optimize-Volume], CimExcep
tion
+ FullyQualifiedErrorId : StorageWMI 43022,Optimize-Volume
Application log:
defrag: 257
The volume Vol_Tier2 (G:) was not optimized because an error was encountered: The operation requested is not supported by the hardware backing the volume. (0x8900002A)
If I format this volume to NTFS everything works fine. Had no such problem in Server 2012 R2.
Guess defrag.exe is not working with new ReFS v3.1

IO Implications of Using Higher Allocation Unit Sizes
It's a pretty common practice for SQL backed file stores to be formatted with 64k allocation unit size. SQL sort of has its own file system that sits ontop of NTFS anyway, so its a very large single file.
But, is using that 64k as a standard for a regular file store a good idea?
I'm trying to understand specifically what is going on at like the disk read/write head level when it comes to picking an allocation unit. Let's say I have a volume and its using 64k allocation unit size. Let's say I have an application that is copying some
files, but is also writing to log files frequently. Let's also say that for diagnostic reasons, the logger opens the file (for append), writes the log message, flushes, then closes the file. It might do this many many times during the session.
Given the above, Is this a true statement?: If the logger writes 10 bytes to the file, the entire 64k allocation unit is re-written (so IO of 64 bytes written occurred). If the logger writes a 1000 byte message, again, 64k is actually written.
Or, is it smarter than that, and will only write the specific number of bytes related to the file IO operation?

Best practice use for S2D cluster running Hyper-V
Hello,
I am running Hyper-V on a Storage Spaces Direct cluster with 4 nodes (server 2016 DC), being managed by System Center VMM. I am running multiple VM's, both windows and Linux on top of this cluster.
Recently there has been requests for running Docker directly on the cluster nodes to be able to run Docker Linux containers on Windows, this would require that Docker be installed on the node host servers of the S2D cluster.
Question: Is it not the best practice to use the nodes solely for Hyper-V in my setup, and not introduce any other software/application on the server hosts?
I do realize I can run VM Linux machines on the cluster and run Docker on-top of the VM's, but that is not the request that is being made.
Thank you for any response.

storage spaces direct in combination with file server for general use
For our company am I looking for a big storage solution. We are producing videos and we need around 500 tb per file share. We need 3 file shares with the functionality of the file share for general use. We need quota, permissions etc. But when I have s2d
have enabled the only possibility is the sofs. I don't see any drives for failover role "file server for general use" what is the way to go? Do I need to use sofs or is it not possible at all? btw. i like the bandwith increase with sofs so if i can
use sofs i would be happy.

FTP Server - Path Redirect
I set up a FTP server (Win7) over the Internet Information Services (IIS) Manager. I use it to transfer a LOG file from a controller to the Physical Path in the FTP Server. It is working but it is putting the LOG files into dated subfolders (C:\FTPClient\Year\Month\Day...). I think this is being created by the Client. Regardless, is there a setting in the FTP Server settings to redirect the LOG to only get put into the Physical Path without the subfolders?
Thanks,

Storage Space backed volume goes offline when free space decreases
One Windows Server 2012 R2 Standard.
Storage Spaces used for backups.
Pool (pool-01) created on physical disks: 8 x 2,73Gb HDD (total size of pool - 21,8Tb)
Virtual disk (vd-01) created on pool: 19,1Tb (parity, fixed provisioning) -- obviously one 2,73Gb disk reserved for redundancy
Volume (F) created on virtual disk: 19,1Tb NTFS
No disk was added or removed after creating of storage pool (over year ago)
Problem: when free space on volume F decreased to 2,73Gb (exact size of one physical disk, backing the pool), any write operation brings volume "Offline".
Event log contains this errors:
- Virtual disk {68de283b-0725-11e8-80fd-94de80240aef} has failed a write operation to all its copies.
- An error was detected on device \Device\Harddisk11\DR11 during a paging operation.
- The system failed to flush data to the transaction log. Corruption may occur in VolumeId: F:, DeviceName: \Device\HarddiskVolume20.
- The disk cannot be written to because it is write protected. Please remove the write protection from the volume %hs in drive %hs.)
After that I can bring volume "Online" from Disk manager with no problem, clean up some space, and it works till when free space on volume decreased to 2,73Gb again.
Status of all Pools, Virtual Disks, Physical Disks - OK, Healthy (not Warning, Degraded, InService)
Used Space on all disks is evenly distributed for all eight physical disks (since creation of virtual disk):
- capacity - 2,73 TB
- total used - 2,73 TB
- free space - 256 MB
What is the problem and how to resolve it?

How to connect to windows server through my PC using FileZilla?
Hello,
Prior to my question I want to clarify that I'm a beginner in this field, so please forgive me if my questions appear stupid.
This is what I'm trying to do:
I have a local server where we store data and that I currently access through remote desktop (using IP, username and password). I want to use FileZilla Client to communicate with this server, so that I can create users, configure their permissions to read and write to a server location. I tried to connect to it through FileZilla Client using FTP but failed to do so. Am I doing this wrong? Is FileZilla server needed in this case? How do you think I can do this?
My server has a Windows Server 2012 R operating system.
Thanks in advance!

Windows 10 Storage Space, installed Server 2016, can't access
My desktop was running Windows 10 Home, and I had two 3TB HDD's setup in Storage Spaces. I switched jobs and got a Server 2016 Standard license and installed it on my desktop, and now don't see, nor can find the drives other than in the BIOS. I don't see
the disks or volume, any thoughts on how to get it recognized and connected? If not, if I reinstall 10, will it show up again?

Support for Work Folders Environment
Hi All,
We plan to build Work Folders based on Windows storage server 2016 using HP StoreEasy hardware. We plan to implement on two AD sites. Two Windows Storage Servere 2016 will be configured as DFS servers with two ways replication : \\corpdomain.com\WorkFolders\ .
Users on site AD-1 will be connected to windows storage server located on site AD-1 and users on site AD-2 will be connected to windows storage server located on site AD-2. Work Folders will be installed on those two servers.
Is this configuration supported for Work Folders? Could we use single login url for all users or we should build two separate url for work folders access?

MS Deployment of Storage Spaces page not showing support for NVME SSDs
In the official documentation for Storage Spaces on Microsoft's site, the article called "Deploy Storage Spaces" posted 7-8-2018 (which also says it applies to Windows Server 2019) found here: https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/deploy-standalone-storage-spaces
In the section titled "Disk Bus Types" it shows support for the following:
- Serial Attached SCSI (SAS)
- Serial Advanced Technology Attachment (SATA)
- iSCSI and Fibre Channel Controllers
WHY is NVME not listed ?

Incorrect File Count.
Hello,
I copied files from a Windows Server 2012 R2 fileserver to a Windows Server 2019 STD fileserver with DFS enabled. I used robocopy to copy all relevant files, however, explorer does not show accurate folder size and file count on the WIN SRV 2019. I used robocopy in test mode again to check if there are missing files, all files were transfered.
There is a LARGE discrepancy when it comes folder size and file count between the two servers.
All servers are up to date.

S2D two node cluster - Network Design
Hello Guys,
I want to install a two node S2D cluster and I have 2x 25Gbit RDMA-capable adapters on each server (and more adapters for LAN traffic). The question is just about my RDMA-traffic:
Usually, the documentations talk about creating a SET-Team out of my two 25Gbit/s adapters and building two virtual Adapters that act as two fault domains, for example:
vNIC: 'Ethernet (Storage1)' in VLAN 10 and 10.0.10.0 /24
vNIC: 'Ethernet (Storage2)' in VLAN 20 and 10.0.20.0 /24
The question is: Why should I create a team for the RDMA adapters at all? Wouldn't it be enough to just directly connect the two servers with two cables and configure a different network on each cable?
Thank you!

Storage Replica - Log service encountered a corrupted metadata file
Hi,
I have a WS2019 stretch cluster lab running Storage Replica Async and I have managed to break the replication, hoping someone can suggest how best to recover from a scenario like this.
It was working fine, and I actually enabled Deduplication on the cluster file server and tested that out. It appeared to be ok, but then I attempted to move the cluster group to another node and at this point Storage Replica failed with this error:
Log service encountered a corrupted metadata file.
I assume that the cluster may not have liked the fact that there were writes going on at the time the async disk replication attempted failover -- whether standard filesystem writes or Deduplication optimisation I'm not sure.
Now that it is in this state, how do I recover? If I attempt to online the disk resource it comes online for a few seconds then repeats the above error. Is there a way to repair or reset the log without starting from scratch? Or do I just need to disable replication and recreate it?
Thanks,
Simon.

Storage Replica fail over testing
I am trying replace our current DFS with Storage Replica. I've setup a prod file server and a dr file server. I've created a SR partnership using the following command:
New-SRPartnership -SourceComputerName "prodserver" –SourceRGName rg01 -SourceVolumeName "d:" -SourceLogVolumeName "e:" -DestinationComputerName "drserver" –DestinationRGName rg02 -DestinationVolumeName "d:" -DestinationLogVolumeName "e:"
I see that data is replicating fine.
I am trying to test fail over by shutting down prodserver. On the drserver, it shows that the D:\ is ReFS and is not accessible. I tried running the following command to make drserver primary:
Set-SRPartnership -NewSourceComputerName "drserver" -SourceRGName "rg02" -DestinationComputerName "prodserver" -DestinationRGName "rg01"
I get the following error:
Set-SRPartnership : There is no partnership between source replication group rg02 and destination replication group
rg01. Please check that partnership has been removed from all computers.

Storage Spaces Reference Site
Hi
We are looking at Microsoft Hyper-V with Storage Spaces to replace our VMware infrastructure. I would like to ask if anyone is running this in a production environment and would be willing to share their experience.
We are looking at having 2 separate clusters (2 sites). Each environment is likely to be running around 40-50 Virtual servers. The most IO intensive being exchange and a SQL cluster(not large databases, I'd like a reasonable IO capability). Standard File servers, web, print etc with normal corporate usage.
We had a conference with a Solutions provider, they were quite negative on Microsoft SS. I am a tech myself and am not inclined to make judgement calls based off one persons opinion, especially when they admit to no real world operational experience.(outside of a few installations)
I would appreciate any feedback people are willing to offer.
Thanks

Can't copy .wav file from my NAS device to any Windows device. "Error 0x80070490: Element not found."
Hi,
I have a NAS device in my home network (Drobo 5N ... https://www.drobo.com/docs/start-drobo-5n/), running the latest firmware. I use my Drobo to store media files (FLAC, MP3 and movies).
Today I just noticed that I have some specific files that I am unable to copy from my NAS device via Windows Explorer to my Windows 10 laptop machine. These are .wav files that I had downloaded from the internet (specifically, I bought a vinyl record of a band that I like, A Perfect Circle, and I received a code in the vinyl packaging that allowed me to download high definition .wav files of the album from their website).
When I downloaded these .wav files originally, I downloaded them to my Macbook Air and then uploaded them from my Macbook to the Drobo from there. I've done this before with other files though, and no problem.
When trying to copy these files from the Drobo to my Windows machine I get the following error:
"An unexpected error is keeping you from copying the file. If you continue to receive this error, you can use the error code to search for help with this problem. Error 0x80070490: Element not found."
I am running Windows 10 Enterprise, Version 10.0.17763 Build 17763. It is a Dell laptop.
I also just tried to copy the file from the NAS device to a Windows 2016 server machine that I also have in my network, and I am getting the same error.
I just tried via FTP to download the files from my NAS device to my Windows machine ... that worked (and the .wav files play perfectly)! So, I only seem to get the error via Windows Explorer.
I am able to stream the .wav files to a music player on my laptop (specifically, the open source music app VLC), and they play correctly! I can also successfully copy them back from the NAS device to my Macbook Air!
I am not having issues copying most other files to and from the NAS device to my windows machine. I have about 2TB of files on there, and a random sample of tests show me that most will copy. It just seems to be a certain group of .wav files (again, that I didn't create originally). They start the copy process, and then it seems to fail right at the end.
If I look at the properties of the files through windows explorer (i.e. through \\NASdevice\share\folder\filename.wav), I don't see anything special; all properties of the files like Read-only, Hidden and Archive are not selected. Security looks the same as all the other files (including the ones I am able to copy).
Any ideas of things that I can try?

I get an error when managing ServerFolders
I created a 100Gb partition for the OS and 400Gb as a D: drive
I thought that 100Gb was enough until I realized that the server was backing up the clients and left me with 0 bytes free on C:
I went to the Storage management and tried to manipulated the folders from within ServerFolders and got errors with all tasks.
I tried creating a new folder: got an error.I Tried moving folders: error with sometimes: missing folders while I did check it. It was present.
Can you tell me why this sections is completely unmanageable... ??? It goes without saying that I am logged in as Admin.
My main goal is to move the Client backup folder to D:.
Thanks
