Abstract
Method and apparatus for preventing concurrency violations among resources in a clustered computer system is described. In one example, a system call is intercepted at a node in the clustered computer system. The system call identifies a target resource. An assigned state of the target resource with respect to the node is determined. The system call is handled at the node based on the assigned state. For example, the system call may be intended to bring the target resource online. The system call is handled by failing the system call at the node if the assigned state indicates that the target resource should be offline at the node. The target resource is allowed to be brought online if the assigned state indicates that the target resource can be online.
