Abstract:
File system availability during local path failure of a non-server node is provided by generating a server database of one or more server nodes having access to a storage device of the file system. The storage device is accessed by a non-server node over a local path to implement one or more input/output (I/O) operations. Upon failure of an I/O operation over the local path, the server database is queried to identify one or more server nodes having access to the storage device. One or more subsequent I/O operations for the storage device are implemented using the one or more identified server nodes. After a restoration of the local path is detected, I/O operations for the storage device are then implemented over the local path.
