A distributed filesystem operating on a distributed computing system uses existing local filesystems as building blocks. A cluster filesystem layer is added above the local filesystems to handle functions necessary for a distributed filesystem, such as data coherency. A meta-data stub is developed to flush meta-data from the local filesystem to a storage device. In one embodiment, the meta-data stub is a copy of the flush portion of the meta-data portion of a local filesystem. Additionally, the distributed filesystem supports a plurality of coherency algorithms and variable granularity. A user may select the coherency algorithm that best suits the computer system and granularity that best suits the access patterns of the computer system.

1. A method for making a distributed filesystem, said method comprising:developing a first stub on a first node of a computing system, wherein said first stub is configured to flush meta-data of a first local filesystem operating on said first node to a storage device, wherein said first stub is accessible to a first filesystem interface layer operating on said first node; and developing a second stub on a second node, wherein said second stub is configured to flush meta-data of a second local filesystem operating on said second node, wherein said second stub is accessible to a second filesystem interface layer operating on said second node; wherein said interface layer on said first node is configured to communicate with said interface layer on said second node.
