Subject Rack aware question.
Date Wed, 23 Mar 2016 15:07:22 GMT

Suppose we change the racks on VMs on a running cluster. (We need to do this while running
on Azure, because sometimes when the VM gets moved its rack changes).

In this situation, new writes will be laid out based on new rack info on appropriate replicas.
What happens for existing data ? Is that data moved around as well and does it happen if we
run repair or on its own ?

Thanks !
