Highly available cluster virtual disk system

摘要: A cluster implements a virtual disk system that provides each node of the access to storage device cluster. The high availability such may be accessed and data requests are reliably completed even in presence failure. To ensure consistent mapping file permission among nodes, stored highly available database. Because database nodes failure, will have data. transport interface is provided establishes links between manages links. Messages received by transports conveyed destination via one or more configuration modified during operation. Prior modifying configuration, reconfiguration procedure suspends waits for pending complete. performed reflect new configuration. then updates internal representation resumes issuing requests.
