Abstract
A computing device receives a request from a host for a shared lock on a resource. The computing device obtains an exclusive lock on the resource using a locking data structure that is stored on the storage domain. The computing device subsequently obtains a shared lock on the resource for the host by writing a flag to the locking data structure, wherein the flag indicates that the host has the shared lock on the resource. The computing device then releases the exclusive lock on the resource.
