摘要： Directory traversal in a scalable multi-node file system cache for a remote cluster file system, is provided. One implementation involves maintaining a scalable multi-node file system cache in a local cluster file system, and caching local file data in the cache by fetching file data on demand from a remote cluster file system into the cache over the network. The local file data corresponds to file data in the remote cluster file system. The local namespace emulates the remote namespace and is created on demand. Access to data further involves performing directory traversal for the cache for the remote cluster file system by creating a directory structure on demand.

摘要： Scalable caching of remote file data in cluster file systems is provided. One implementation involves maintaining a cache in a local cluster file system and caching local file data in the cache by fetching file data on demand from the remote cluster file system into the local cached file system over the network. The local file data and metadata corresponds to the remote file data and metadata in the remote cluster file system. Updates made to the local file data and metadata are pushed back to the remote cluster file system asynchronously.

摘要： The amount of memory being utilized to store token state information is monitored. In response to the monitoring, one or more actions are taken. For instance, if the monitoring indicates that too much memory is being used to store token state information, then one or more actions are performed to reclaim memory and/or obtain additional memory elsewhere. These actions may include informing one or more clients to reduce their cache sizes, thereby relinquishing tokens; reducing or eliminating one or more byte range token trees; and/or migrating the token server from one node to another node. If the monitoring indicates that additional memory can be used for storing token state information, then one or more client nodes are informed that their cache sizes can be increased.

摘要： Asynchronous messages are used to prefetch and/or relinquish tokens used in providing locking of shared resources. A message is sent to prefetch one or more tokens, and prior to receiving a reply for the message, another message (e.g., an acquire) is sent for at least one of those tokens. Similarly, a message is sent indicating a voluntary relinquish of one or more tokens and without having acknowledgment that the relinquish request was processed, a further message (e.g., an acquire) is sent for at least one of the tokens. Multiple tokens may be acquired and/or relinquished in a single message to the token server. This reduces message delays and overall message traffic.

摘要： A computer system manages files shared by first and second heterogeneous clients. The first client exhibits a first protocol such as SMB and the second client exhibits a second, different protocol such as NFS. A first protocol converter receives requests from the first client to create, read and update the files, and converts the requests to corresponding requests exhibiting a common protocol. A second protocol converter receives requests from the second client to create, read and update the files, and converts the requests to corresponding requests exhibiting the common protocol. A file manager is common to both clients and both protocol converters, receives the converted requests exhibiting the common protocol and executes the requests in a name space and data area which are both common to the first and second clients. The name space stores names of the files and the data area stores the files. The file manager provides access by each of the clients to files and names of the files created by the other client. A common lock manager is provided for the common name space and common data area. The system also supports second and third name spaces and data areas dedicated to the first and second clients, respectively.
