My TrueNAS version is:25.10.1 - Goldeye
For the last week or so I have been copying media files from my desktop computer to the specific media folder on TrueNAS.
Now, as I wanted to copy another file over, I got a message saying error while copying , and then checking ‘more details’ it says that the filesystem is read only.
I then checked the permissions for the dataset, and nothing has changed that I can see.
Help please
Was this media folder mounted by another service you’re using? It’s possible that service changed the permissions. Also, are you using ACL’s or basic Unix permissions?
The media folder was mounted in or on my Linux Mint desktop computer, and when I try to view the permissions of the said folder on my desktop, it says ‘The permissions on media on freenas.local could not be determined’
I have been using an ACL for the same folder for many years, without any problems, but earlier today I changed it to a NFS4 open ACL where everyone had full read write and whatever else,
Even after a reboot of TrueNAS there is no difference, the file system is still read only.
How can I change it to write as well.
Thanks
When you made this change did you check the box to apply permissions recursively?
Yes I did
Can we see a screenshot of your dataset permissions please.
Also how are you mounting in Mint GUI or CLI? If CLI can you share your mount command.
Can you also share zpool status to make sure the system is happy and confirm the dataset doesn’t have the readonly property enabled.
Just out of curiosity, is this what happens when you set a quota and fill up the quota? Makes sense that it would prevent itself getting more full by becoming read-only.
Defo worth checking that.
I am mounting the said folder in Mint GUI. I go to network/freenas/Media, then have to enter my Linux Mint password, and the folder opens up
Out of interest I tried a portable ssd on another Mint computer, and then tried to copy a file across to the media folder, same error, read only file system
Can you also show a view of your datasets, highlight the one in question and also your SMB Share config.
Did you check the quota on the dataset and also if readonly was on?
The Media folder is under WinShare, which has all the different media folders . IE:
/WinShare/Media/Music, etc
How or do I check the quota on the dataset
I hope this what you are asking for.
Does your username and password on your Mint client match that of your username on your TrueNAS?
No it doesn’t, as I am using my Mint login password, which I have always used.
Ah that could be the issue then. Try and create a new SMB share pointing directly at /WinShare/Media and see if that works.
Select the dataset in the UI and look at Data Space Management. Also check the Details section to make sure readonly isn’t on.
UPDATE:
Sorry second look you already have this. So did you change the ACL type just on /WinShare/Media and nothing else?
Yes I changed the ACL type on the Media folder, and no other folders.
Sorry, how do you mean ‘Try and create a new SMB share pointing directly at /WinShare/Media and ‘see if that works.’
Do you mean to create a new Media share folder, because the name already exists.
Ignore me I thought you were just sharing the parent WinShare. I presume all was working fine before you changed the permissions from POSIX to NFSV4?
Have you restarted the SMB service since you made that change?
Just done it now on or for the WinShare/Media folder, but even after a reboot no change
Have you checked quota and readonly isn’t enabled?
Ok but where do I check quota on the dataset.
Options within the dataset in the UI.
