Hello,
After I upgraded from Leap 15.4 to 15.5 my backup disk has become read-only and as a result of that my Backup jobs are failing. They cannot write to the disk. How do I change it so I can write to it?
When I go to properties > Permissions > Advanced permisions. Eveything in there is greyed out.
A bit unclear to me. Do you really mean that your whole disk became read-only? Or do you mean that one (or more) file systems became read-only?
When the latter is the case, please show e.g.
lsblk -f
to see what disks, partitions and file systems you have. And
mount
to see if the file system(s) is mounted read-only.
dante@localhost:~> lsblk -f

I think i fixed it now but I’m not sure if it’s done properly. I opened Dolphin as super user. And then went to properties and put my username into the user field. And that gave me ownership of the disk i think.
It is mounted but for some reason it appears as removable disk. Whereas the main SSD where the OS is installed is pictured as internal disk.
I assume it is this one?
It is mounted rw, thus that is not the problem.
As I have no btrfs experience, I will leave this to others (and hope they come soon).
That is unclear, properties … of what?
Properties of the Backup disk.
Never heard of. Where do you see that?
I assume some GUI program?
It is the first screenshot I posted above.
I have no idea what it is.
Dolphin is about files. And I see no correct absolute path to a file in that screenshot.
The only place where a disk can be seen as a file (a basic concept of Unix/Linux) is as a device file like /dev/sda. But that is not what the screen-shot says.
And yes, it is handled as a spontanious connected disk. It is apparently not in /etc/fstaband is mounted “through the desktop”. And that explains the strange mount point. And that mount point is owned by user dante and of course protected against (mis)usage from other users.
