What is the status of your Datacenter?
Are these hosts both operational?
Are you experiencing other problems with your storage other than the inconsistent task state?
Do you see the KeyError: 'VERSION' message related to domain b6730d64-2cf8-42a3-8f08-24b8cc2c0cd8 also on Node02?
Did you experience any disaster (power outage, FC storage outage, network, etc) around the time this started happening?
