Managing file systems and file-based data storage

摘要

Embodiments of the present invention can comprise systems and methods for managing filesystems and can provide a programmable filesystem with active rules and policies, an n-tier network filesystem, stack mounting, a union filesystem with write-through semantics, a filesystem middleware with selective delegation, a filesystem with a statistical warehouse and/or other management functionality.

1. An apparatus comprising a set of computer instructions stored on a non-transitory computer readable medium and executable by a computer processor to:
store, in a rulesbase on a server associated with a filesystem on a network, a set of programmable rules controlling at least one of storing data on the filesystem and accessing data on the filesystem, wherein each rule in the set of programmable rules comprises a pattern and an action, wherein the pattern specifies one or more criteria for initiating the action; receive, from a filesystem client operating on the network, a filesystem request indicating a requested filesystem operation associated with a filesystem object, wherein the filesystem request is communicated according to a network filesystem protocol; compare the filesystem request to one or more of the programmable rules in the rulesbase and identify a pattern of a rule in the set of programmable rules with the one or more criteria satisfied by the filesystem request; determine occurrence of the action associated with the identified pattern for the rule relative to performance of the requested filesystem operation based on an impact of the associated action on the requested filesystem operation; and selectively execute the associated action after performance of the requested filesystem operation in accordance with the determination.
