One embodiment of the present invention provides a system for elevating a secondary file server to act as a new primary file server in a highly available file system. Upon determining that a primary file server in the highly available file system has failed, the system promotes the secondary file server to become the new primary file server. During this process, the new primary file server scans file objects to look for a file lock indication. Upon finding a file lock indication, the new primary file server converts an associated file identifier into a virtual node. Otherwise, conversion of file identifiers into virtual nodes is delayed until the first time a file is subsequently accessed by the new primary server, thereby speeding up the failover process.
A method for elevating a secondary file server to act as a new primary file server in a highly available file system, comprising:
A computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for elevating a secondary file server to act as a new primary file server in a highly available file system, the method comprising:
An apparatus for elevating a secondary file server to act as a new primary file server in a highly available file system, comprising:
