Abstract
Techniques are described for remastering shared resources among nodes in a cluster, while minimizing the number of resources that are unavailable for access ('frozen') during the remastering operation. Only the resources that are being remastered from one node to one or more other nodes are frozen, whereas the other resources that are not being remastered are not frozen and are, therefore, still accessible. For example, in the context of a database cluster, there is no longer a need to freeze the entire database during a reconfiguration remastering operation. Consequently, during the remastering operation requests for access to the resources that are not being remastered can be processed and locks granted thereon.
