It’s been a very long time. I have been running Truenas 12 and just upgraded to Scale 25. I started fresh and just planned on importing my pool, all when well. Now i’m having all kinds of issues accessing my files over windows SMB. I can see the folders on my network is just says I don’t have. I…

I ended up running the “/chmod 755 /mnt/tank” and it did change the “Access” to the dataset!! It opened it up for me to be able to add my “ryan” user along with make changes to other “Access Control List” users/groups! It looks like my main Dataset was set at “770”. Anything i’m missing or messed …

It looks like you are trying to share the root or parent dataset. That isn’t allowed now. Create a child dataset along with the proper users and share that by SMB. Root, admin and truenas_admin aren’t allowed SMB sharing. Your data is still there. You will just create new child dataset. Test yo…

Hi! I have (3) child datasets under my main dataset “tank” already from my import. I tried a new one that i made on my new Scale and it created it, i can see it on my windows PC, but can’t access it either.

Can you post a screenshot of the whole Datasets window from the GUI. Sent a DM too. I usually use Snipping tool in Windows 11 for screenshots.

OK… i can post screenshots now…had to go do some looking around and talking with the ChatBot first… I appreciate your help in advance as well! [image] [image] [image]

I have a user, ‘smbuser’, that is the owner of the shared, child dataset. You look to have ‘root’ Your root dataset Tank looks to have NFSv4 permissions. Mine is just showing Unix permissions. I think you should try creating a new, test dataset and set it up for SMB sharing by following the Docs…

I’m not able to edit my dateset permissions. [image] Tried to set up a new Child Dateset. [image] I clicked on Pool List this time… but still get that permission issue when trying to add “ryan” user. [image]

In services, can you stop the SMB service? Then go to Shares, Windows(SMB) Shares and see if it lets you edit Share or Filesystem ACL. I’m wondering if service needs to be stopped. You can try on the newly created test2 so we don’t change anything on your current settings.

Turning off SMB didn’t change anything. I tried to “Strip ACL” from “test2” and was able to do so, but still not able to access from my PC. Just able to see all the folders. [image] After stripping it, it looks like this. I tried to change the user and group to my but it didn’t take the change. …

@awalkerix Can you offer any insights on how to fix this dataset and sharing problem?

I found this discussion but i’m confused on how to do this exactly. I’m not good with code other then “copy and pasting” … sorry… [image] Cant change permissions on root dataset TrueNAS General its scale, i forgot to add it but its there now slight_smile ok, so i did tha…
