I upgraded a 2 node cluster with RF = 2 from 1.0.9 to 2.0.11. I did rolling upgrades and upgradesstables after each upgrade. We then moved our data to new hardware by shutting down each node, moving data to new machine, and starting up with auto_bootstrap = false.
When all was done I ran a repair. Data went from 250GB to 400 GB per node. A week later, I am doing another repair, data filling the 800GB drive on each machine. Huge compaction on each node, constantly. Where should I go from here? Will scrubbing fix the issue? Thanks
