It seems that the storage domain is corrupted.
Can you please run the following command and send the output?

    vdsm-client StorageDomain getInfo storagedomainID=<sdUUID>

You may need to move the storage to maintenance and re-initialize it.

Can you please share more info?
- The version you are using

Is the VM running or down while creating the snapshot?
