SCRUB fails to end / fails to restart after shutdown

Bugs
1

My box experienced an unexpected shutdown during the execution of a scrub, and I am now unable to schedule further scrubs or cancel the currently “running” one through the webui.
The box is running 3.8.16-8, but I believe the problem originated when it was running an older version. The problem has persisted across restarts and upgrades.

@arbrick Welcome to the Rockstor forum.

Thanks for bringing this up again and apologies for missing this the first time around. Would you like to open a new issue on the GitHub rockstor-core repo describing this buggy behaviour as we definitely need to get this ironed out. As you demonstrate with the status command there really is no balance in progress and so the bug would seem to be in the UI layer. I’ve only done a little work in that area so can’t say quite what’s going on but at least if we have an issue it should get sorted in time. You could link back to this forum thread for context.

Thanks for your patience and clean reporting.
