DETERMINING STATUS OF A HOST OPERATION WITHOUT ACCESSING THE HOST IN A SHARED STORAGE ENVIRONMENT

摘要

Implementations of the disclosure provides for determining status of a host operation without accessing the host in a shared storage environment. A method of the disclosure includes acquiring, by a processing device, a lease on a storage volume associated with a storage domain. The lease grants the processing device exclusive access to the storage volume. Responsive to acquiring the lease, a data structure associated with the storage volume is modified to indicate that data of the storage volume is invalid. An update operation is initiated with respect to the storage volume. Upon completion of the update operation, the data structure is updated to indicate that the data valid and the lease on the storage volume is released.
