ReadyNAS 104 - 3EP943E6002F4 - Cannot set file access. Check if specified user or group exists...
The unit is setup with local accounts. Adding/Changing permissions have worked fine historically. Last week the firmware was upgraded to 6.7.4 and there were no issues including permissions until yesterday. 3 users who had RW access to a share lost write ability despite the permissions being RW. The unit has beeen rebooted and now permissions cannot be set for anyone, new or existing.
Error below is the message I receive if trying to change permissions from the shares settings page.
Cannot set file access. Check if specified user or group exists, or if another file access change is already in progress.<br />facl_change fail uid=107 gid=600

Hi again,
Well so the SMB access it totally open to anyone. That is fine I guess. You are then limiting permissions based on file permissions. There is nothing wrong with that, but I would not recommend doing that when only using Local Users and not AD. Reason being that file permissions from the GUI can be fiddly at times. Normally, it is sufficient to restrict access on the network level (SMB Permissions) in setups that don't involve larger scale solutions (such as AD integrated storage devices).
Network permissions is just easier to manage from the GUI.
Anyhow, if you want everyone to gain access again you can make the change from the command line quite quickly (login over SSH). I am not sure why the reset of file permissions does not work from the GUI. Anyhow, here is how you can reset access to everyone on those 3 share.
Run these 4 commands one after another. They might take a few minutes to complete based on the amount of data in those shares. You will get the promt back when they are finished running. Basically, it will reset the file permissions back to R/W for everyone. You should then be able to restrict access via GUI afterwards (if you wish to do so). But I would suggest to use SMB permissions instead of file permissions for your setup.

Thanks for the reply,
That was my thought as well. The 3 users who lost permissions to the share I removed thinking re-adding them would resolve the issue. However, now I cannot add any users to the permissions.
I have rebooted 3x as well. I even tried creating a group but I cannot add the group to the permissions either.

Not AD joined. Just local users.
Basically we bought a facility. At the moment there's some basic networking equipment and this ReadyNAS unit that came with the facility. The share just is a place for the departments to store files.
I log into it remotely with the factory admin account. There are about 10 shares on it. It doesn't matter which share, when I go to permissions and select a user for RW, click append, the circle does its circle motion for about 10 seconds then the user is not on the access list.
If I do it through the share settings window I get the message in the original post.

Hi again,
Well that looks better than I expected. There are no "orphan" file permission memberships on the shares. OK well, then the issue is something else. If you look at those file permissions any user can write to the following shares (from a file permissions perspective): Backup dailycommunication Database designs Emails Maint Music Pictures PPAP Tooling Videos
I assume none of these shares are giving you trouble?
The share "Documents" only the admin user can access. But this a default share that you don't use anyway?
Here are 3 shares that stand out permission wise:
The share "Engineering" have these file perms: User Marco: R/W Group users: R/W Everyone else: R/O
The share "office-admin" have these file perms: User guest: R/W Group guest: R/W Everyone else: no access This is a bit of a strange permission setting, is that intentional?
The share "Quality" have these file perms: User quality: R/W Group QA-RW: R/W Everyone else: R/O
The shares you are having difficulties with, are they any of those 3 shares above?
Also, as StephenB mentioned - what permissions are you setting on the Network Permissions (SMB permissions), for the shares you are struggling with?
Re: ReadyNAS 104 - 3EP943E6002F4 - Cannot set file access. Check if specified user or group exists..
You are pretty much correct on everything. I did not configure the permissions, a non-IT manager did them previously and this is not a long term solution but needs to work in the interim. So the odd setup was from someone who didn't know better and it's an "is what it is" setup for now on that one.
The 3 shares that stand out... Yes, none of those will accept permission changes. Quality is the one that initially started giving us the issues.
On the SMB Everyone and Admin have RW. Allow Annonymous access box is ticked. No other users right now have a tickbox available to even select RW for a user. However, previously there was this option and if I ticked the RW box and saved it would precess but then not add the new permissions and had the error that is in the original post.

Thanks, they can now RW to the drive. Yes the permissions are setup horribly but this unit came with the facilty we bought and is only an interim solution while we get our servers setup and installed.
