Abstract
Facilitating access to data in a network, is provided. One implementation involves maintaining a scalable multi-node file system cache in a local cluster file system, and caching file data in a cache by fetching file data on demand from a remote cluster file system into the local cached file system over the network. The local file data corresponds to file data in the remote cluster file system. Upon disconnection from the remote cluster file system, all file operations are supported at the cache. Then, upon reconnection to the remote cluster file system over the network, the remote cluster file system is synchronized with the information cached in the cache during the disconnection even in the presence of failures.
