For the last day or two I've been seeing "No space left on device" in nzbget and qbittorrent (but other containers are working just fine). What happens is that the nzb downloads fully but then fails due to "No space left on device". Or in qbit, part of files download and then Error due to "No space left on device"

 

 

I have previously had this happen when my cache was full and re-creating docker.img fixed that. In that case, no docker containers would work. My containers (plex etc) work just fine.

 

Set up:

- system and appdata are set to use cache_nvme

- Media is set to use cache_ssd

- cache_nvme has never been full

- cache_ssd got 100% full a few days ago

 

 

Things I've tried:

- I ran scrub on my disk (nvme cache disk where docker.img is, and cache_ssd where downloads would go first) and it found 0 errors.

- I've re-created docker.img from scratch. No luck.

- I completely removed and then re-installed nzbget (restored settings conf file only). No luck.

- Made sure docker.img is nowhere near full: `/dev/loop2       20G   10G  9.8G  51% /var/lib/docker`

- Made sure downloads directory is not full. Running `df -h` inside the nzbget container shows that `/downloads` has plenty of space left: `shfs             34T   26T  7.7T  77% /downloads`

- nzbget is able to download the files but fails on unrar. So clearly the "No space left on device" is transient.

 

I'm at a total loss here and would appreciate any help.

 

Thanks

Fixed by running a balance on cache. Btrfs is a giant pita
