Abstract
Managing failover operations on a cluster of computers, including: identifying, by a failover hold module, a failure to access data storage in the cluster of computers; preventing the execution of all read operations directed to the data storage that were received after the failure to access data storage was identified; executing all write operations directed to the data storage that were received after the failure to access data storage was identified, including writing data to a cache; identifying that a failover to alternative data storage is complete; executing the held read operations, including reading data from the alternative data storage; and copying, from cache to the alternative data storage, the data written to the cache as part of the write operations.
