Grafana has some ZFS dashboards available, e.g. https://grafana.com/grafana/dashboards/328 Uses the Prometheus data source, so needs a bit of work to get it running under unRaid. Both Grafana and Prometheus have unRaid plugins, so its just the ZFS / Prometheus integration. Might be nice to integrate it with the unRaid Grafana dashboard here: https://grafana.com/grafana/dashboards/7233 Its on my list of things to look at, but haven’t had time...

Just wondering if anyone using ZFS uses drive spin down? does it work through the UnRAID GUI, or is it done through CLI? Same for SMART tests? thanks

Thanks all, that’s great feedback. I originally looked at adding cache, but then thought that even if i did, it still left read speeds at a single spindle once the data was off-cache. If I moved to striped, then I could reuse my disks and get better performance without needing to buy SSDs! The other thing I looked at was Ubuntu 19 + Cockpit GUI. This gave me Docker & KVM as well as the (beta) Cockpit ZFS GUI manager. Would have preferred Centos 8, but they have moved to Podman instead of Docker and getting the right combination of ZFS / Cockpit / Podman all working together was problematic. Only looked at FreeNAS as it was the quickest to deploy but ProxMox sounds like it could be worth a look as well. Looks like I have some testing to do over the Christmas break! Happy Holidays!

How is the stability of ZFS under UnRAID? How about CIFS speeds, using 10gbe? Was just about to move away from UnRAID to FreeNAS for the striped array speed increases when I noticed this. Really like the UnRAID ecosystem, but the array write speed is a killer for me; using striped disks via ZFS might plug that gap!
