umount.nfs, umount.nfs4 - unmount a Network File System

umount.nfs*/ dir/ [-fvnrlh ]*

umount.nfs and umount.nfs4 are a part of *nfs*(5) utilities package, which provides NFS client functionality.

umount.nfs4 and umount.nfs are meant to be used by the *umount*(8) command for unmounting NFS shares. This subcommand, however, can also be used as a standalone command with limited functionality.

dir is the directory on which the file system is mounted.

-f

Force unmount the file system in case of unreachable NFS system.

-v

Be verbose.

-n

Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip deleting an entry.

-r

In case unmounting fails, try to mount read-only.

-l

Lazy unmount. Detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it is not busy anymore.

-h

Print help message.

For further information please refer *nfs*(5) and *umount*(8) manual pages.
