Description
Set a threshold for the acceptable number of down stores for a server to even come up. Due to configuration issues or due to multiple disk failures, it is possible that too many stores are unable to start up. In such cases, it is probably wise to not let the server start up. Today, a server can start up even when none of the stores do, which may result in these servers receiving requests they cannot process.

Research direction
Start by tracing the server startup path and how store startup failures are reported. Determine how an acceptable down-store threshold should be configured and enforced, then verify that the server does not come up when too many stores—or all stores—fail to start.
