ABSTRACT:
A method for managing a plurality of servers is disclosed. Each server of the plurality of servers has access to data stored by other servers. The data is stored to one or more data storage devices. Coordinating information is written for the plurality of servers to a master mailbox record. The coordinating information includes data that each server uses to recover after a failure by a server. The master mailbox record is stored on a selected storage device at a location known to the plurality of servers, and the selected storage device is designated as a lock storage device. A plurality of lock storage devices is chosen so that in the event of failure of a server of the plurality of servers, at least one lock storage device will be available to the remaining servers.
