Determining status of a host operation without accessing the host in a shared storage environment

A system comprising:

• a memory storing a plurality of storage volumes;
• and
• a processing device, operatively coupled to the memory, to
• acquire a lease on a storage volume associated with a storage domain, the lease granting the processing device exclusive access to the storage volume;
• responsive to acquiring the lease:
• modify a data structure associated with the storage volume to indicate that data of the storage volume is invalid;
• initiate an update operation with respect to the data;
• update, upon completion of the update operation, the data structure to indicate that the data is valid;
• and
• release the lease on the storage domain associated the storage volume.

A non-transitory computer-readable storage medium comprising executable instructions that when executed, by a processing device, cause the processing device to:

• acquire, by the processing device, a lease on a storage volume associated with a storage domain, the lease granting the processing device exclusive access to the storage volume;
• responsive to acquiring the lease:
• modify a data structure associated with the storage volume to indicate that data of the storage volume is invalid;
• initiate an update operation with respect to the data;
• update, upon completion of the update operation, the data structure to indicate that the data is valid;
• and
• release the lease on the storage domain associated the storage volume.

A method comprising:

• acquiring, a processing device of a shared storage system, a lease on a storage volume, the lease granting the processing device exclusive access to the storage volume;
• responsive to acquiring the lease:
• identifying a data structure associated with the storage volume on the second storage volume;
• and
• determining, by the processing device, whether an update operation related to data of the storage volume is complete in view of modifications to the data structure.
