Shares not writable from Windows - Error "you require permission from Unix User/Root to make changes"

weirdaljr · 2. September 2014

Hello All,

Sorry to ask this, but I tried searching and read a bunch of SMB threads, but didn't see the fix for this problem.

I got a fresh OMV 1.0 install on Debian 7. I have made my Shares and they are all visable on windows PCs on the network, but when I try to write to one of the windows shares I get "you require permission from Unix User/Root to make changes".

I am looking for these folders to be public on my windows network so I have them set to "Guest Only" in OMV. Not sure what Im missing, Im sure it is basic, but I couldn't find the answer yet. What should I check?

As you created the shared folder it didn't cross your mind that maybe it could be necessary if more than just the owner has write priviliges?

Guests are neither owner, nor group (which can't write either). So what you forgot is to set the permissins to r/w everybody.

chmod a+w /media/uuid/sharedfolder via CLI will fix your problem.

You should use the recursive modifier if you want to apply that permissions on child elements already present:

Code

chmod -R a+w /media/uuid/sharedfolder

Hi davidh2k Sergio,

I'm having the same issue having followed the setup instructions for OMV. I have my files hares in place and can access from my PC. But I can't make any changes e.g. drag and drop new or existing folders/files from PC to OMV. From your solution above I think this will resolve my issue but i'm struggling with the CLI example you've provided. I've found the UUID and I know the name of the Shared folder. What is the /media/ component I need? Where can I find this? Any help great fully received.

The last post is from 2014. That is nine years ago.

Did you create a fresh shared folder or are you pointing the shared folder to an existing folder on the filesystem?

I set up OMV yesterday and created a fileshare 'NAS' as per shot below. This is a fileshare for an existing folder on the SSD. I can Paste items from my PC into the NAS folder but not into any of the sub folders. I also can't move anything I do paste into NAS to any of the subfolders. I'm sure it's a permissions element I've missed.

and thankyou for responding! Sorry I didn't see the dates

Try if it work with a completely new folder. If it does, we need to reset the permissions of the existing folder. There is a plugin for this called resetperms

Goatboy · 15. Oktober 2023

Hi, this looks like the answer. I set up a new folder in within the NAS fileshare. I can drag and drop to the new folder but not to the original folders. Should I be using this for my next steps? https://wiki.omv-extras.org/do…6:omv6_plugins:resetperms

Thanks again for the support!

Yes, Install omv-extras first and then install the plugin from the GUI of OMV.
