I have been using Unraid for a very long time. Lately, on /mnt/disk5, which is a btrfs drive, it has 1TB free but says "No space left no device." How do I resolve this? This mount is fixed to write on /mnt/disk5.

 

root@titan:/mnt/user/iTunes# mkdir x
mkdir: cannot create directory ‘x’: No space left on device

Attached are diags.

Note: I did fix the bad share names for disk4, cache, etc.

If I go directly to that mount (/mnt/disk5), I can write. But writing to this share /mnt/user/iTunes, where disk5 is the only "included" drive causes it to show the "No free space" error.

Post a screenshot for that share settings.

Here's the screenshot:

Does the folder already exist on that disk? Click on the share, then "compute" and post a screenshot.

That was it. Folder was present only on Disk 1, which I guess I removed at some point and set to Disk 5 only. Added Disk 1 to the included drives, and viola! 

 

Thanks for all the help!!!

 

Since the split-level was set to manual, it wouldn't work without the folder already there.
