unable to rebalance in/out other nodes if one node in the cluster has a non-default path for data files

steps to repro
set up one node :
use non default path for data , then create a sasl bucket with views.

then add second node.
rebalance fails with this error

Rebalance exited with reason

its not clear to me what we are doing here or why we are trying to run rm -rf on the existing node in the cluster

diags attached.

i tried even failing over or removing those nodes but rebalance fails right away.

diags attached as well.

this is potentially a c-blocker
