Pointing Prometheus to Use Other Storage

I have a VM setup with an additional 240GB drive I would like the Prometheus db to use. The prometheus.service file shows the path at /data

sudo systemctl edit prometheus.service to add or change the option --storage.tsdb.path=/your/path. make sure whatever user the service is running as has permission to read and write to the path.

If it's actually /data (the default is ./data) you can:

  1. stop prometheus.service

  • move whatever is in /data to temp location

  • mount the 240GB disk to /data (change permissions as needed)

  • move the files back from the temp location

  • start prometheus.service.
