Are you running node_exporter in Docker?

Yes

What did you do that produced an error?

Is there some metrics about bare disk(not mounted) capacity?

What did you expect to see?

What did you see instead?

No, not currently.

A good starting point would be exposing /sys/block/*/size, which is measured in 512-byte sectors (regardless of block device actual sector size).

working on a PR for this here https://github.com/prometheus/node_exporter/pull/3068

would appreciate some feedback before I go much further, thanks :smiley:
