Abstract
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.
