Claim 0:
1. A method comprising:
receiving a request for exclusive access to a volume;
determining, for each node in a cluster, a score based on data associated with an environment of the node, wherein the determining includes:
using data from sensors at sites of the nodes in the cluster to determine a value for each sensor based on whether a response from the sensor corresponds to normal or abnormal temperature, power, and seismic activity conditions at the environment of the node,
assigning a magnitude of the value to be positive if the response from the sensor corresponds to normal temperature, power, and seismic activity conditions at the environment of the node,
assigning the magnitude of the value to be negative if the response from the sensor corresponds to abnormal temperature, power, and seismic activity conditions at the environment of the node, and
summing the values for the sensors to determine the score for a particular node;

identifying, based on the scores, a node to grant exclusive access to the volume; and
granting exclusive access to the volume to the identified node.
