[ovirt-users] problem to create snapshot

[Ala Hino]

[Please always CC ovirt-users so other engineer can provide help]

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.
