I think that Drivepool is running in the background. I can see my pool drive and interacted with a few files on it successfully.
If I want to open the drivepool or drivescan GUI I just see "starting service (xxx minutes)". I have tried obvious things like rebooting and restarting the service. I have seen it reach several hours without giving me access to the GUI.
Update: apparently I have read only access... I cannot figure out how to turn on error logging from the instructions I googled. I tried editing the settings json file directly but no joy.
