Node decomission - SLOW

Trying to decomission 4 nodes.  Moved them to /decomissioned 3 DAYS ago....about 100TB of data on them that needed to migrate to other nodes.  Nodes are all connected via 40Gbps Infiniband.

When we first started, data migration was screaming at upwards of 12Gbps...moving 4TB per hour.  But over time it just seems to be getting slower and slower...3 days later and there's still 15TB of data to move.

Another other thoughts to speed this up??

Does it matter if I keep the disk balancer enabled during this process?
