Hi All

I still see drop outs from SMB shares and management of files (Using the file manager Opus it can delay operation until it reconnects).
But transferring files is a nightmare.

Anything I can change in the SMB special config?

I'm not aware of any SMB issues with Windows 11, other than needing to create a user initially. What exactly are you experiencing? Also please post the diagnostics saved when the server is having issues.

What happens if you use the default Windows File Explorer (aka, Windows File Manager)?

EDIT: One more thing to try. Spin up all the disks in the array (MAIN tab of GUI) before you start file managing.

I actually always used the internal File manager until now. (Like today it was my way of trying to create a workaround)
Its copying a large file (Large 20G) its playback of a media file over the network, its listing folders in a share and a "frozen" windows window not reacting over time....

I don't want to just drop a logfile what can I do to test this? in a good way?
Any docker I can install to monitor network to and from the machine?
I have a Unifi UDM pro as a router and many switches 24 ports could Unifi be the problem?
My network from the server is a collection of 10G + 2.5G + 2.5G all placed in a switch supporting these speeds.

Sorry if I am rambling... its just becoming a big problem when you want to move some data or just haven a open share on your windows PC
Any special setup in regards to win 11 and the user setup? (It just worked)

UPDATE:
I just found this.. (Trying this out to see if it makes a difference - already have access and mapped shared drives though?)

 

Select Start, type gpedit.msc, and select Edit group policy.

 

In the left pane under Local Computer Policy, navigate to Computer Configuration\Administrative Templates\Network\Lanman Workstation.

 

"my edit find the SMB over QUIC and enable it"

 

Open Enable insecure guest logons, select Enabled, then select OK.

found if you are using a local account and not a Microsoft account then maybe you need this instead i used like 4 hrs to find a fix

a. On the Start Menu search, type gpedit and start the Edit Group Policy app (i.e. Local Group Policy Editor). If you are using Home edition, skip to step 8.

b. In the console tree, select Computer Configuration > Windows Settings > Security Settings> Local Policies > Security Options.

c. Double-click Microsoft network client: Digitally sign communications (always).

d. Select Disabled > OK.

And the command:
Set-SmbClientConfiguration -EnableInsecureGuestLogons $true -Force

Did you try this?

Most of the time, delay in displaying files and folders (and copying files), can be traced to conditions of trying to manage large numbers of files and folders in a single share. Plus, to generate the information to 'fill' the file listing pane of files/folders of your file manager is dependent on how many items have to be processed. Unraid does buffer some file data in RAM but often it has to retrieve it from the physical disks which requires spinning up any disk which contains files in the share.

Most of the stuff, you did in the the Group Policy Editor won't help with this situation. (All you did was increase your security risk if you already had any access at all to the files.)

The Diagnostics file (if it should be requested or you want to post it for completeness) can be anonymized when it is generated.

Confusions reins around logging into Samba. Actually, it is more difficult to generate a login using MS account then with a local account.

See this post and the next one in this thread to create a secure login to your Unraid server:

https://forums.unraid.net/topic/191221-some-musings-on-smb-and-samba-and-unraid-and-windows/#findComment-1561582

Be sure that you see the rules in the 6-20-2025 Edit for creating a login name. These rules generally preclude the use of a MS account to do the login.

Thanks Frank1940 ! - I actually thought about this:"
"One more thing to try. Spin up all the disks in the array (MAIN tab of GUI) before you start file managing."

But I changed the performance settings on Unraid to performance from powersavings (I thought that would spin up drives when initiating a file transfer or accessing the server?)
So you mean manually go to the UI and press the spin up all drives? before initiating a file transfer? sometimes its just using filemanager to find a file... (Not a good thing on a file server LOL)

Yes I see the confusion and I probably just butchered my security adding these settings - I did have access before to the SMB shares just not reliable.
The funny thing is that I know I am running many dockers and they are all on fast nvme's and my RAM usage is 50-60% and my i9 is keeping up with everything so I invested in 10G card and a 10/2.5G switch beliving that would solve it :-)

diagnostics-20250815-1102.zip

On a sidenote, "In the old days" I remember that you usual keept CPU 0 for the Unraid OS to use.
But looking at the pinned options I can only exclude CPU 0 from everything and then set it to a App/Docker?
What is the correct way to always keep one of the power cores to the Unraid OS? (I was just thinking this could help?)

Wow! I just looked at your Diagnostics! You have 39 HD's and SSD's in your array and pools. And I saw one share that appeared to have files on 28 Data disks and one pool. The smallest disk that I saw was 10TB and the parity disks were 20TB. I would not ask that you say how much data you have stored on your server but it must be north of 200TB and the number of files must be in the tens (if not hundreds) of thousands! You do realize that you could be physically accessing every disk in your array to assemble all file metadata to construct the directory listing plus the time to sort it into the display format that you want to see it in.

Unless, you were every careful on how you put that data on your server, I don't how to expect that a file manager can be quick as navigating through the resulting file morass.

The spin down delay is controlled by two settings. The first one for all the disks is here:

And for each individual disk from this page for that disk:

The Performance setting is intended to allow you to select the tradeoff between CPU/GPU power consumption and performance. Both Intel and AMD provide for this choice in their chip sets.

I am going to ping @JorgeB and see if he has any thoughts.

I'm seeing some strange lsof errors logged; boot in safe mode, disable Docker and VM services temporarily, and post the diagnostics during the problem.

Hi Frank1940

Yes in my last upgrade I got carried away got myself a special case that could max out the 30 drives Unraid supports :-) and then some extra for ZFS in the future.
Before Unraid many years ago I had a Synology with 24 drives that ran on a very small CPU. The current Unraid server have run anything I have thrown at it - the i9 is a beast even downclocked to avoid any problems it runs everything.

So far Unraid have been great even if I have all these drives the source folder of any file is collected in the same subdir, so copying a folder is from a single drive.
I thought the plugin to help list your files cached the drives listings of the Root drive? (Maybe that got lost in the latest update of Unraid ?)
Cant remember the name of it? it would help index and list your root folders quickly but yes I cant see that gone an not anymore had it on my old server

I just noticed this in my error log while transferring I access the shared drives through the Unassigned plugin:
And I can see the rootshare is taking longer (Freezes).

Sure JorgeB I can do that tomorrow, safemode transfer large files and do a new diagnostic when it freezes....

There is the Dynamix Cache Directories plugin. However, it is quite old without a lot of active support and (as I Remember from many years ago) has a problem with large numbers of files/directories when there is not enough RAM to support everything being in the available RAM at the same time. It ended up doing constant flushing of the RAM of old data to add new data being read off the array disks. It could end up with almost continuous disk activity as the complete data of data required was never in RAM at one time.

I use the plugin but I only cache my Media files which about 5000 total items. The RAM required is small enough to fit everything in the available RAM and not be flushed.

Disable that and retest transferring to a normal share.

Thanks JorgeB - But I really like the root share feature :-(
So I need to remove it completely? (Had a hard time setting that up between to Unraid servers)
Cant I just do the test on a normal share?

Thanks Frank1940 I installed the plugin again (Cant hurt) and I only selected the media folders (I don't know if my RAM can handle that?)

I don't recommend ever using a root share; I've seen many different issues because of that, but you can test with a normal share first to see if there's any difference.

It has been years since I even looked at the setup for this plugin. I just had a look at it and now I find that I have it disabled! I can not remember why I did that. So I am not going to be much help in to you...

Ok thanks again for helping me out!

I just did a manual SMB mapping to my movie drive and I get an error?
The funny thing is that I have copied SMB access to this folder from other folders and they all work!
ALL OTHER FOLDERS IS WORKING and I can map them to my PC except this one


Example if I try to access any of the other folders as a direct mapped share it WORKS!
Only movies is giving this error, also if I go to the root share I have access to all folders.

UPDATE:
Okay I might have found the "Culprit" I am stupid!, for some reason my Tailscale client on my laptop works perfectly for all folders except the Movie folder?
Turning the Tailscale connection off and I got access to the share instantly , I don't know if this has anything to do with the transfer dropouts? But I cant rule it out
NOTE I did have the Allow local network enabled on Tailscale!

Anyway I will do the safeboot and test again from multiple PC's and do the diagnostic

Look at this Uncast video about setting up Tailscale on Unraid. There is information beginning at about 26 minutes about subnet routing networking. You have to make sure that the subnet that you are advertising will never be the same as the subnet you have the client running on. ((You have to be really careful about Laptops that are used on both home and the road!)

(I have just started playing around with Tailscale in the past month so I have just reached that point where I am really dangerous...)

Safeboot and +100G of file transfers... No errors!
I will keep the Dynamix Cache Directories plugin for now cant see much RAM usage.
And I can see a speedup in listing subdirs and files when looking through the file manager its more snappier on my laptop!

The only thing that I really like about the root share is that if you move large files you dont really move them it just changes the source directory (At least it seems like that - instantly moving files)

Remember that in the safe mode, Cache Directories is NOT installed! Oh, you can disable it rather than uninstalling it to see if it is an issue.

Hi Gents!

I need a little help cant wrap my head around this???
I have SMB shares mapped directly to my laptop and they all work!
But when I "read" the same settings to my appdata folder I cant map the drive?
I keep getting strange messages like:


So I am thinking the only difference is that my appdata is located on its own cachedrive?

So something prohibits the access?

I have exactly the same settings for shares and users!

And I cant remove the master share before I can access the appdata folder must important directory :-)

Docker containers can set their own permissions, so it is not unusual to not be able to access their contents over the network.

You WILL be able to access the contents using the Dynamix File Manager that is built into Unraid 7..

See this post:

Run smbstatus and see what Share access users are logged in.

I can see that 'administrator' has read/write privileges but I can't see what other users have. I would also wonder about using "administrator" as a 'user name' as it could be a reserved name on some systems. BTW, the share, appdata, is normally not shared out via smb as it is the location where Docker containers store their system files files for their own internal use. Getting in there and doing file management has the potential to really screw things if you don't what you are doing. Plus, some of the files and directories don't the proper permissions for normal SMB access. IF a Docker container is generating user files for some specific purpose, it should be writing those files to the array and using PUID and GUID with a UMASK to generate files in a User Share with proper credentials and permissions.

strikeout of "their system files" and added "files for their own internal use". Added "in a User Share" in next-to-last sentence.

Yes but normally I need to access some configuration file, and most of them is not supported by the Unraid filemanager example would be .yml files and others.
Its so much easier to just change the values on you PC than logging into the UI.
Sofar the only way has ben to use the mastershare-pool and that gives me other problems

you can add new extensions to be treated as text files by editing the config/editor.cfg file on the flash drive.
