1. A method for managing a file system in a shared storage system over a network, wherein instructions stored in a memory are executed by one or more processors to perform actions, comprising: instantiating a file system epoch counter associated with a plurality of file system objects; and instantiating a file system facility to perform actions, comprising: employing one or more of a plurality of storage devices of the shared storage system to provide access to the plurality of file system objects that are associated with one or more directories or files in the file system; and in response to receiving a request to modify a first file system object, performing actions, including: determining when one or more file system objects are current with a quota by employing the system epoch counter to compare a current epoch value to an epoch value previously associated with the first file system object, wherein the comparison reduces latency and computational resources that are employed to determine when one or more file system objects are current with the quota; and identifying, without having to traverse the entire file system, one or more file system objects that are non-current with the quota; when the comparison is equal, allowing an increase or a decrease in a size of the first file system object; when the comparison is unequal and one of the first file system object or one or more parent objects of the first file system object are enforcing the quota, disallowing the modification to the size of the first file object; and when the comparison is unequal and the one of the first file system object or the one or more parent objects of the first file system object are unenforcing the quota, allowing the modification in the size of the first file object.
