Hi there, glad to be part of the Covecube community now!
I've just yesterday set up a new pool with all my (scanner checked) spare drives, moved all my data to it and configured some balancing and file placement rules. Nothing too awkward, though, I guess.
Now I wanted to eventually empty some drives that were just in there temporarily, though not yet remove them from the pool. So I used the options on the "Drive Usage Limiter" plugin to set some of my drives to neither contain (new nor existing?) duplicated nor unduplicated data:
The settings worked in that a "real time file placement limit" (I think that's what it is called?) was set for the drive:
But unfortunately, no action whatsovever made the pool actually fulfill that limit! The "Pool Organization" shows up as a long green bar, when I hover it, it says:
Whenever I click on "Manage Pool" -> "Re-measure..." or click the pool organization arrow -> "Re-balance" or even "Troubleshooting" -> "Recheck duplication" ... all ends up with some processing and stopping in that condition.
So I took a look into the error log and found that all those operations are stopped by something like this:

I guess that's a bug?
