Abstract: Disclosed is a method for preventing ghost writes in a multi-computer system. A first computer in the multi-computer system issues one or more write requests to a storage device, each write request normally being effectuated after being pending for a time. The method generally comprises the steps of detecting a condition indicative of a failure associated with the first computer and preventing the effectuation of write requests issued by the first computer to the storage device and pending at the time of the detected condition. In one embodiment, the condition indicative of a failure associated with the first computer comprises at least one of the group consisting of a reduction in the number of known operating computers in the multi-computer system, and a state change of a volume group associated with the computer on the storage device from inaccessible to accessible and a reduction in the number of known operating computers in the multi-computer system.
