ABSTRACT:
A method may involve: a node included in a cluster looking up a file in a metadata name cache; in response to a miss for the file in the metadata name cache, the node creating a metadata name cache entry for the file in the metadata name cache, where the metadata name cache entry includes a copy of a cookie associated with metadata allocated to the file; in response to a lock on the metadata changing state for the node, the node modifying the cookie associated with the metadata, where the lock changes state for the node in response to a request to a global lock manager for the lock on the metadata; and comparing the copy of the cookie stored in the metadata name cache entry to a current value of the cookie associated with the metadata to determine if the metadata name cache entry is valid.
