Abstract
Techniques are provided for managing access to resources that are shared by a cluster of nodes. One aspect of the invention is to require verification that a quorum is a valid quorum prior to enforcing the access rights specified by a node that is a member of the group of nodes holding the quorum. Further, the verification that a quorum is a valid quorum prior to enforcing access rights occurs only if the quorum associated with the specified access rights is suspected to be invalid.
