Abstract
Direct read in clustered file systems is described herein. A method as described herein can include determining, for a write operation on a resource stored by a data storage system, as initiated by an initiator node, a reference count for the resource, the reference count comprising a number of target storage regions of the data storage system to be modified by write data during the write operation; facilitating conveying, from the initiator node to a lock coordinator node, the reference count for the resource; facilitating conveying, from the initiator node to respective participant nodes that are respectively assigned to the target storage regions, the write data and a key value for the write operation; and facilitating causing the respective participant nodes to convey respective notifications that comprise the key value in response to the respective participant nodes writing the write data to the target storage regions.
