/**
* Thrown when a paritioned region is configured for disk persistence, and part of the data is
* stored on members that are known to be offline.
*
* With a partitioned region, the keyspace is segmented into buckets which are assigned to
* individual members. If all members that are storing data for a particular bucket are offline, any
* attempt to access or update data in that bucket will throw this exception.
*
* If you see this exception, that means that you need to restart the members that host the missing
* data.
*
* If you receive this exception when attempting an operation that modifies the region (such as a
* put), it is possible that the change was actually persisted to disk before the member went
* offline.
