I recently copied the folders from my WD NAS (which acts as a source to my Vero4K and the destination for Torrents via the Vero) to a back-up ext4 drive whilst I re-formatted the NAS owing to a couple of problems. The folders were then all moved back. But since then I get a ‘Read Only File System’ on Transmission. All the copying was done via drag and drop in windows (using Paragon software to be able to see the ext4 drive) in the hope that I didn’t mess up file permissions. The NAS works fine playing media to the Vero, the relevant share is Public and I can drop in and out of its folders from windows. I found a very similar problem in Using transmision and get error: read only file system but ran out of brain cells part way through!

which I think means I should have permission? Any help gratefully received as always.
Well Group is set as 501 and not OSMC which might be one of your problems and Vero_4K_Back_Up is owned root/root which is the problem on that folder.
Thanks for that. Is there a suitable command to correct that? And out of interest, given this worked prior to copying, would the windows method of transferring files have caused that?
Try
sudo chown -R osmc:osmc /mnt/Vero_4K_Back_Up
Possible
As someone who moves large amounts of data on a regular basis I would never trust Windows for the task…use this great free program instead.
Thanks for the help, ans sorry for slow response - work got in the way. I tried the suggested command and;
root@osmc:/mnt# ls -lah

I’m guessing that’s not as expected?
thanks for this - I’ll look at this tonight. I’d only gone down the windows route after tying myself in knots with rsync/ftp etc, and falling foul of permissions problems previously! Seems like it didn’t help.
Your directories have a plus sign at the end of the permissions, indicating that they have additional access control list (ACL) permissions, probably inherited from Windows. (It’s not clear what happened, but your chown command seems to have added a plus to the permissions of /mnt/Vero_4K_Back_Up, where no ACL had originally existed.)
Staying with /mnt/Vero_4K_Back_Up for the moment, you’ll probably need to install the acl package:
sudo apt-get update
sudo apt-get install -y acl
then provide the output from these two commands:
grab-logs -A
getfacl /mnt/Vero_4K_Back_UpThanks for the help - logs;
https://paste.osmc.tv/iwotuyidid
and;
root@osmc:~# getfacl /mnt/Vero_4K_Back_Up
getfacl: Removing leading ‘/’ from absolute path names
file: mnt/Vero_4K_Back_Up
owner: root
group: root
user::rwx
group::r-x
other::r-x
I see you rebooted the device, meaning that /mnt/Vero_4K_Back_Up was no longer mounted. Could you run the following:
sudo mount /mnt/Vero_4K_Back_Up
getfacl /mnt/Vero_4K_Back_Upapologies for the reboot - I seemed to recall it was a requirement when providing logs, sorry.

Is the WD NAS formatted as ext4 or NTFS?
You could try to remove the extended permissions:
cd /mnt; sudo setfacl -R -b Vero_4K_Back_Up
ls -l /mnt
If you see user:group of 501:osmc but without the + sign, try the chown again:
sudo chown -R osmc:osmc /mnt/Vero_4K_Back_Up
ls -l /mnt
(PS I think the reason the original chown “created” the ACL is that you were originally showing just the mount point – but afterwards, we saw the mounted share, which has the ACL.)
root@osmc:~# cd /mnt; sudo setfacl -R -b Vero_4K_Back_Up
setfacl: Vero_4K_Back_Up: Read-only file system
setfacl: Vero_4K_Back_Up/Base_m.c: Read-only file system

since it still has the + I didn’t re-try the chown command in case that did more damage. I’ve always assumed it’s ext4 but only seen that in the spec for it’s more advanced cousins, so not 100% sure. Thanks for the help on this - annoying that my choice of copying via Windows to avoid any permissions issues seems to have backfired.
It does think that it’s read-only, so we’re a bit stuck, AFAICT.
If you still have the backup copy, it might be worth copying it back a second time to the NAS, assuming that it’s also ACL-free. 
Doh! Time to check the backup. But regardless - thanks very much for the help.
Hi again - tonight I attached the back-up drive ready to start moving the files over but thought I’d just try your suggested command one last time;
cd /mnt; sudo setfacl -R -b Vero_4K_Back_Up
and after repeating it for each folder;
drwxrwxrwx 51 501 osmc 4096 Aug 27 02:04 4K_Films
drwxrwxrwx 6 501 osmc 4096 Aug 31 19:55 Downloads

drwxrwxrwx 3 501 osmc 4096 Aug 26 20:38 Vero_4K_Back_Up
and Transmission has access to the Downloads folder again! No idea what changed apart from re-connecting the other drive, but happy for now.
Excellent! 
Did you also succeed in changing the ownership to osmc:osmc?
No - did try that for each folder as per your previous suggestion;
sudo chown -R osmc:osmc /mnt/Vero_4K_Back_Up
but it made no difference to any of them. Not sure if that ownership thing will come back to bite me at a later date but for now it’s working great again. So thanks again for the help!
