Abstract
Provided are a computer program product, system, and method receiving at a cache node notification of changes to files in a source file system served from a cache file system at the cache node. A cache file system is established at the cache node as a local share of a source file system at the source node. The source node establishes a local share of the cache file system at the cache node. Notification is received, from the source node, that the source node modified a source control file for a source file at the source node. In response to receiving the notification, a cache control file, for a cached file in the cache file system, is updated to indicate the source file at the source node is modified. A request is sent to the source node to obtain data for the source file indicated as modified.
