Getting this error in Events for several flexgroups.

I've familiarized myself with checking for FlexGroup imbalances in System Manager and from the CLI.

Since upgrading to 9.13.1 I see there are options in SM and the CLI to "rebalance" an FG.

But launching a rebalance never seems to finish. The default is to give it six hours before timing out. It then gives up with no work done.

Right now I'm running it on a ~8TB FG with 12 Constituent Volumes, ranging from 122GiB to 2.44TiB in size. It's been running for over two weeks now and it's still "Scanning" with 0 bytes moved. I think I gave it 60 days.

Is this new "rebalance" feature just vaporware?
