Adding Drives to a Storage Space to Increase Usable Size/Space?

$
0
0

I currently have a 4x8TB Storage Space setup with parity, created with the following command on Windows 10 Pro (version 1909)

New-VirtualDisk -StoragePoolFriendlyName "Pool" -FriendlyName "Array" -Size 28.5TB -ProvisioningType Fixed -ResiliencySettingName "Parity" -PhysicalDiskRedundancy 1 -Interleave 65536 -NumberOfColumns 4


I'm now trying to add another 8TB disk and in a few days I'll be adding 3 more for a total of 7. When I added the 5th disk I was only able to slightly increase the size of the pool, from 21.5TB to 24TB. Whenever I try the command

Resize-Partition -DiskNumber 8 -PartitionNumber 2 -Size 28TB

I get the error "Not enough available capacity" - looking at the Pool in the Windows applet I see "Using 30.6 TB of 36.3 TB pool capacity" with the green bar not filling the space fully.

When I run

Get-StoragePool "Pool"
I get "Size 36.38 TB" and "AllocatedSize 30.7 TB"

I've run "Optimization" on the pool but still can't increase it. What am I missing? I'm still at a place where I can recreate the pool, if I had to, but that would waste several days of IO time loading the array.

Thanks!

need help troubleshooting Work Folders permission error

$

I'm attempting to move an existing Work Folders user to a new computer.  When the user signs in to the new computer Work Folders fails.  (We use Group Policy to configure Work Folders when the user signs in to Windows.)  Looking at the Event Viewer on the new computer for Work Folder errors there are two that occur simultaneously:

Sync Share discovery failed. Server URL: https://hqfileserver.flyfish.wan/sync/1.0; Partnership type: User Data; Error: (0x80c80014) There's a problem with the permissions of your folder on the server. Email your organization's tech support and ask them to make you the owner of the folder.
Event id 517

Configuration of Work Folders through Group Policy failed. 
Error: (0x80c80014) There's a problem with the permissions of your folder on the server. Email your organization's tech support and ask them to make you the owner of the folder.
Event id 10

Any ideas on how to troubleshoot or resolve this issue?

I've confirmed the user is owner of their Work Folder folder on the server.  

There are no related entries in the SyncShare Event Logs on the server. 

I had two other users sign in to the new computer mentioned to confirm the Work Folder client is working.

High Latency High Bandwidth File Services performance

$

I have a scenario where we will have an office with ~1000 users (Windows 10 clients) connecting to Win2016 File Servers in a datacentre, over a long-distance high-bandwidth 10Gbps circuit between cities with ~12ms latency.

I want to know what (if any) tuning is required (server side, or client side) to ensure that users receive fast file services performance with that kind of latency.

Is it possible to make it perform like the file server was on the local client subnet?

The client workloads are mixed general purpose SMB. Home drives, MS Office documents, CAD documents.

Physical Server Full

Hi All,

We are in a bit of a dilemma.

We have an ageing physical server which is critical to production. My attempts to clone and migrate to VMware has fallen on deaf years. The problem we have is that the C: on the server is forever filling up. I have run the disk cleanup etc but there is never anything of note to delete. Does anyone know what files could be deleted from a server - I was thinking of old event log files etc, etc, or anything else such as old or updated windows files.

Regards.

Peter.

Mapped network drives disconnect after some time

$

Hello everybody,

A customer is running Windows Server 2019 Terminal and File servers. The terminal servers map network drives to a file share on the file server. We have problems with two applications, because the network drives are in a disconnected state after some time:

- One has an Access database residing on the file server, accessed from several users. Access crashes on disconnect because its file handles to the database file do not work any longer.

- A .net desktop application is used and its .exe and .dll reside on the file server. The users start the .exe from the mapped drive. When the mapped drives goes into the disconnected state, and the application needs to load something from one of its DLLs, the application crashes with an unhandled exception. The event log says that the .net runtime could not continue because the network connection was disconnected.

We have followed https://support.microsoft.com/en-us/help/297684/mapped-drive-connection-to-network-share-may-be-lost and set the LanManServer parameters to disconnect after 5000 instead of 15 minutes (on the file server), and set the LanManWorkstaition parameters to disconnect after 65535 instead of 600 seconds (on the terminal servers). But this did _not_ help.

I guess we do not need to discuss whether Access databases are fantastic or file servers are fantastic or running .exes from file shares is fantastic ;-) The question is simple:What can we do to keep the network drives connected, please?

Users able to access shares without permissions

$
0

We were migrating some shares today. We're migrating a client to OneDrive for Business Shared libraries, but are still keeping drive maps on the desktops for now.
Our file server has the folder synced to full download and is sharing them.

We configured the new shares via Server Manager on Server 2012 R2 under the File and Storage Services.

We set the NTFS permissions on the folders, Selected a custom path in the share creation (just used SMB Share - Quick) and turned on Access Based Enumeration.

This is in an AD environment.

After the share creation, here's our NTFS permissions (note that the everyone deny is added by OD and can't be removed)

Owner - Administrators(Server\administrators)

Deny - Everyone - Delete Subfolders and files
Allow - Administrators (Server\Administrators) - Full Control
Allow - SYSTEM - Full Control
Allow - CREATOR OWNER - Full Control
Allow - Finance (DOMAIN\Finance) - Full Control

The share creation from Server Manager set the SMB share permissions to Everyone - Full Control.

After checking a few machines, we noticed that users that are NOT in the finance group (and do not have ANY NTFS permissions on this share) were ABLE to access and navigate the share.

We changed the share SMB permissions to remove everyone and then set just the Finance group to full control.
This then denied users not in the Finance group the share, as we want.

My understanding is that NTFS permissions (or the more restrictive permissions) trump. If smb is set to everyone, but only a group is given permission on NTFS, only that group can access.

Am I incorrect here? Is there something I'm missing?

According to fsutil-behavior  the DisableDeleteNotify Disables (1) or enables (0), what does the (Disabled) mean in the result if the current configuration is enabled (0)?

Issues with Storage Migration Service

$

0

Hello!

I am currently in the process of testing Storage Migration Service, as I am planning to perform a migration from an old Windows Server 2008R2 file service to a server running a newer Operating System.

However, the product does not work. At all.

I can run through all the inventory steps, and pass the validation with only warnings.

However when I come to the Transfer Step, the operation fails with the message: "Couldn’t transfer storage on any of the endpoints."

Checking the event logs for the Storage Migration Proxy shows the message "Error 50 Operation not Supported"

User being used on both source and destination is a domain admin and a local admin on all server.

User has Full Control NTFS permissions.

Even the computer account is a domain (and enterprise) admin, this was done as part of the troubleshooting.

None of this has resolved the issue.

So can anyone on this board tell me which "operation" it is that is "not supported".


NTFS create files but no delete or modify

$
0

Having difficulty with this as it seems that many file operations infringe on other permissions that aren't expected.

Need to have rights in a folder/subfolder where users can drop files, once there they can read them but not change or modify.

Seems simple but it's not..

Create new folder needs modify as it creates a folder called 'new folder' first then you rename it.

I almost got there by removing 'delete subfolders and files' and 'delete' but once I remove 'append data' to stop modify then file copy operations go awry.  If I copy a file to an empty location from non ntfs, say a share, then it copies the file but then says file exists do you want to overwrite, which of course you cant.  The problem seems to be that the file copy operation initially copies the file 'as is' then needs to modify it to change the creation date.  so although I can just cancel the file exists warning, its annoying and disconcerting to know if its copied or not.

Any ideas most welcome

> 1 TB of disk space taken up by unknown file(s)?

Hi!

I'm on Windows Server 2012 R2, and I recently found that my 2TB C:\ was running out of disk space, which was really surprising.

So I used TreeSize to find out what was taking up all the space, but still it only shows that all the files take up only about 303GB of space. Where did the remaining 1.5 TB go to?

Enabling Auditing on a File Server

If we enable auditing on a file server, what sort of performance hit can we expect?

Also, when we audit a particular folder, is it acceptable to add "Everyone"? And what sort of information does Auditing give us?

Determine Parent Object of moved folder

$
0
0

How do I determine the parent object (not current parent folder) of a folder on a Windows server? When a folder is moved from one place to another on the same volume, it continues to inherit permission from the original parent object, and that is not the new parent folder. This is easily demonstrated by removing inheritance, whereupon I can set whatever rights I want. But as soon as I re-enable inheritance, the moved folder again shows rights not matching the new/current parent folder. And no security change to the parent folder results in any inherited change to the child folder. So the parent object is presumably still the pre-move parent folder. This is also evident in the advanced security settings for the folder, where "Inherited From" says"Parent Object" instead of the current parent folder. If I create another folder manually, it correctly shows the current parent folder path instead of "Parent Object".

To be clear, the fix is easy enough: copy the folder and its contents to a new parallel folder, which will inherit rights from the shared parent folder, then delete the original moved folder that has the parent object retained from before the move. But this assumes the desired result is to allow the rights to be inherited in the current location.

Suppose I instead want to put the folder back where it came from but have no idea who moved it or from where. It is still inheriting rights from a parent object that is not the current parent folder, so the parent object property must exist in the ACL somewhere, and I want to retrieve it. It seems that a change of rights to that other (original parent) folder could have unintended consequences on rights to this folder.

So my question is not about how to fix the folder/files; it is about how to determine the original parent object. I have been curious for years about this: how can I identify the original parent object (not the current parent folder) that was retained as the parent object of the moved folder when it was moved? This would presumably be the parent folder when the moved folder was originally created (or copied to) elsewhere on the same volume.

And while we are at it, anyone have a script that I can run to identify folders whose parent object is not the current parent folder? We will, of course, have times when we do not want rights automatically inherited, but one thing that I want absolutely 100% of the time is for the parent object to be the current parent folder. Anything else will just be chaos.

Copy Deduplicated Files as is without re-hydrating

$

Hi,

My team started to enable deduplication on our research data center due to massive storage requirement.

One challenge we are facing now is that due to the nature of research process, we often need to create copies of large set of data in the same volume for different research projects. However, the built-in copy utility such as robocopy always re-hydrate the deduped files and caused the volume to be filled up. We constantly need to pause the copy process and run dedup before continuing.

Is there a copy tool we can use to copy deduped file (pointers) as is so that the destination files are automatically deduped? Is there anything in Win32 API we can build this tool on top of?

Thanks,

Jason

Folder Permissons

Trying to troubleshoot why a security group can't get access to it. 

Folder is hidden. 

I can get to it on my admin account. 

Two user trying to get to it on their user accounts. 

User accounts are in one SG. 

I have added SG to folder with read, list and read & execute permissions. 

Users logged out, logged back in. 

User aren't able to get to folder. 

I added my user account to folder with same permissions. 

I logged out, logged back in. 

I was able to get into it with user account. 

Added user's account to the folder itself with same permissions. 

Users logged out and logged back in. 

Users unable to get to folder. 

Unsure why they aren't able to get in. 

DFS Name space migration

$

I am not sure to call it the migration or not but the question is:

We have 2 DFS name spaces and 3 name space servers:

2 name space servers on 2012 core DC's (SMB 3.0.1)and one on 2008 R2 DC(SMB 2.1)

Because of this older DC hosting the DFS, some of the client connections from Linux are forced to use CIFS v 2.0 

We want to introduce 2 Windows 2019 servers and add as name space servers and disable the 2008 R2 name space server for the both name spaces and then decommission later on

Looks simple and straight forward but not sure if there are any implications ? If this not recommended, is there any way to force all the connections only served by the 2012 name space servers?

Please share your thoughts and recommendations.

Thanks in advance!

Windows storage spaces incorrectly reporting usage

SQL Server (Server) with an all SSD array - System Build, Configuration, and Recovery

$

Say we setup a SQL Server box with say 12 SSD drives which you would build into 2 pools. 1st pool would be for the database itself, made up of larger capacity drives (perhaps 1TB x 8 drives = 4TB if setup as a mirror on storage spaces), with 2 x Optane in a mirror making up the high write side  of the database (transaction log files, temp DB maybe). The other 2 could be setup as a hot-swap.

Question is - If one of the drives fails, given that we're using Storage Spaces, and are using an ALL SSD array, how long do the hot swaps take to come online if we're talking about total data size on the failed drive of say 1TB ?

The reason it's relevant, is because SSDs tend to fail closer to one another if they're the same age and have the same miles on them (which in this case in this example as they would all be new when the server is built). Because the hot swapped SSD can come online much much faster than a magnetic drive, we reduce the changes that a mirrored pool made up of a single good drive would create havoc.



Creating Cluster SAN Storage

$

I have a 2012R2 host server with VMs configured on an HP MSA1040 using iSCSI.  Only one LUN.

I have added a second server to the rack.

After reviewing quite a bit of documentation I am stuck trying to complete the Cluster Validation tests, in particular WRT the storage.

1. Is it OK to connect the 2nd server to the SAN and should I place the drive Online or can this cause data corruption even if I don't access the drive from that server until the cluster is created?

2. KBs instruct to "run all tests" for the cluster validation but when I did this it took the SAN drive offline and disconnected all of the VMs. Fortunately rebooting the host brought everything back online.  I also received the following ominous error in the Cluster Log: (VMHOST1 is the operational Hyper-V host)

Node VMHOST1.xxxxxxxx.local holds the SCSI PR on Test Disk 0 and brought the disk
online, but failed in its attempt to write file data to partition table entry 1.
The disk structure is corrupted and unreadable.

Any guidance would be appreciated.

Thanks >> Joe
