How-To: Release Stuck NFS Mounts without a Reboot

摘要

Computing environments may revolve around heavy usage of NFS infrastructure. Network areas are hosted and provided by storage file servers, with compute servers mounting the exported areas into their directory tree. Periodically, the mounts expire when not in use and are removed from the directory tree on local machines. If NFS traffic between file servers and compute servers is disrupted, machines holding active mounts will not be able to release them.
