Hi all, not sure where to start. I've been getting the "No space left on device (28) error" for various actions, e.g. mkdir, moving files, etc. I've been unable to locate the cause of it. I had a peruse through the forum but the related posts didn't seem to lead me to any solutions.

 

I got the following to help debug from a df -h, but nothing seems amiss here:

Diagnostics zip attached. Any help is appreciated for this novice here

Media share floor is set to 390G, disk1 has les free space than that, if the problem you have is when writing to that share add more storage or lower the floor.

Thank you @JorgeB, that solved it

I have the same problem, but I have a device that has 5tb free, I'm using mover tuning plugin
