Hi all, I'm running a Prometheus docker container, and I've run into an issue regarding disk space. Despite having hundreds of MB of free disk space, if I attempt to call the API snapshot endpoint `curl -XPOST http://localhost:9090/api/v1/admin/tsdb/snapshot` I receive an error message:
`create snapshot: snapshot head block: populate block: write chunks: preallocate: no space left on device` Output of `df -h` inside my prometheus container: [image: space_left.PNG] With around 518 MB free, I am able to call the snapshot endpoint. However, with less free space than this, the snapshot endpoint returns the error regarding no space left on device. size of my /data folder: [image: data_folder.PNG] I see from this thread <https://github.com/prometheus/prometheus/issues/8406> that potentially 100's of MB free disk space is required to take a snapshot. I am a little surprised that (from what it looks like) at least 500 MB are required to take a single snapshot. Is this expected/intended behaviour of prometheus, or could there be something on my end (perhaps docker related) that is contributing to this issue?
