Comment 1 for bug 1491676

A side effect of this bug is that full EC drives never become unfull.

I have a node with 8 drives, and I took 5 of them out of the ring in order to force more data onto the others. This filled up the other 3. Then I put the 5 back into the ring. 12 hours later the data distribution looks like:

ubuntu@ip-172-30-3-43:~$ df

The 3 "full" drives are still full, due to the errors noted above in this ticket. The ring has rebalanced so the # of partitions assigned to each drive are approximately equal.
