ABSTRACT:
A method for implementing virtual disk reservations on a storage medium for multiple distributed applications. The method includes initializing a plurality of virtual disks, wherein each of the virtual disks is instantiated on a physical storage medium. A reservation status is determined for each of the virtual disks and a first distributed application that uses at least one virtual disk is executed. Upon an update of the reservation status for the at least one virtual disk by the first distributed application, a notification indicator is set to notify a second distributed application of the update. The update is subsequently recognized and the notification indicator is cleared in order to continue I/O for the first distributed application and the second distributed application.
