[Bug] Incorrect Synology NAS Storage Usage #1374
Description
Description of the bug
Lists Only my RAID, and sees it as full.
If I mount using -v /volume1/mnt/host:ro \ Issue is the same. Inside Docker container I see all of the contents correctly.
How to reproduce
On DSM Device Install using Script below:
docker run -d --name=dashdot
-p 7512:3001
-e DASHDOT_ENABLE_CPU_TEMPS=true
-e DASHDOT_OVERRIDE_OS=DSM
-v /:/mnt/host:ro \
--privileged
--restart always
mauricenino/dashdot
Relevant log output
Version file not found. This is normal on from-source builds.
listening on *:3001
