NFS has an inherent problem. It is not very good at knowing if the mounted resource is available or not, so it depends on a response from the host providing the resource - but only after some applications asks for it.

Example NFS4 on a Solaris 10 machine used to hang shutdown when a user executed a cd to the NFS directory, and then just left the process sitting. The machine had zones (virtuals) and some NFS connections were required from zone to zone. Not a great idea.

This meant that if NFS zone1 -> zone2 and zone2 was taken down, the machine would not reboot because NFS could not figure out how close the open file, and NFS will wait for long periods of time for a resource.

You may have what amounts to a similar problem. A user on one machine has an NFS mounted directory open - the directory lives on another virtual or machine. Something happens on the remote and the local one hangs. NFS has problems, avoid it if you can. NFS can negatively affect simple commands like pwd and system calls like realpath() if the parent directory of your current directory has an external NFS mount. And that directory no long is available.

showmount

SHOWMOUNT(8)						    BSD System Manager's Manual 					      SHOWMOUNT(8)

NAME

     showmount -- show remote NFS mounts on host

SYNOPSIS

     showmount [-Ae36] [-a | -d] [host]

DESCRIPTION

     showmount shows status information about the NFS server on host.  By default it prints the names of all hosts that have NFS file systems
     mounted on the host. See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version 3
     Protocol Specification, Appendix I, for a detailed description of the protocol.

     -A      Search for NFS servers advertised via Bonjour.

     -a      List all mount points in the form: host:dirpath

     -d      List directory paths of mount points instead of hosts.

     -e      Show the host's exports list.

     -3      Use mount protocol Version 3, compatible with NFS Version 3.

     -6      Use only IPv6 addresses to contact servers.

SEE ALSO

     mount(1), mountd(8), nfsd(8), mDNSResponder(8)

BUGS

     The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless.  showmount will only display
     the information as accurately as the mount daemon reports it.

HISTORY

     The showmount utility first appeared in 4.4BSD.
