A method for performing file lookups based on tags indicative of file characteristics may involve: a file system storing an association between a tag and a file, where the tag is indicative of a characteristic of the file; the file system storing an additional association between the tag and an additional file that also has the characteristic; the file system searching for files having the tag; and in response to searching, the file system returning identifiers of both files associated with the tag. The returned identifiers may include the files' pathnames or inode identifiers of the files' inodes.

Embodiments of a system and method for distributed file system I/O recovery in storage networks. Embodiments may detect loss of access to a server in the storage network and recover application I/O requests in real-time once access to the server is restored. Embodiments may detect server and/or network failures and store failed and new I/O requests. Recovery from the failure (e. g. network reconnect, server node reboot, or failover, if this is a clustered environment) may be detected and, after recovery is detected, any stored failed and new I/O requests may be sent to the server. In one embodiment, to detect recovery from the failure, a failed I/O request may be repeatedly re-issued until the I/O request succeeds. Embodiments may be implemented in a variety of storage environments, including environments where clients issue direct I/O over a storage network to storage and control I/O over a network to a server.

A node in a server cluster is designated as a quorum disk. The node stores a list of other nodes in the server cluster also designated as quorum disks. The node can replace the first list with a second and more recent list of quorum disks only if the second list is updated on at least a simple majority of quorum disks on the first list.

A bridge in a file server provides a direct link to data storage devices in satisfaction of data requests. The file server has one or more function-specific processors, including network processors (NPs) and file storage processors (FSPs), all operating in parallel and communicating over an interconnect bus. Each FSP is also connected to one or more disk controllers which in turn manage one or more data storage devices. To minimize local bus contention between data storage devices and network communications, separate internal buses are provided in the FSP, one internal bus connected to the interconnect bus for network communications and one internal bus connected to disk controllers for performing I/O operations on data storage devices. The bridge provides a path between the FSP's internal buses so that, for disk access requests, data from a particular data storage device may be sent by the disk controller via the bridge over the interconnect bus to the NP servicing the request with minimal involvement of the local FSP processor.
