autounmountd(8)

autounmountd8

Daemon unmounting automounted filesystems

Usage

autounmountd [-d] [-r time] [-t time] [-v]

Overview

The autounmountd daemon is responsible for unmounting filesystems mounted by automountd(8). On startup, autounmountd retrieves a list of filesystems that have the automounted mount option set. The list is updated every time a filesystem is mounted or unmounted. After a specified time passes, autounmountd attempts to unmount a filesystem, retrying after some time if necessary.

These options are available:

-d

Debug mode: increase verbosity and do not daemonize.

-r

Number of seconds to wait before trying to unmount an expired filesystem after a previous attempt failed, possibly due to filesystem being busy. The default value is 600, or ten minutes.

-t

Number of seconds to wait before trying to unmount a filesystem. The default value is 600, or ten minutes.

-v

Increase verbosity.

Exit status

The autounmountd utility exits 0 on success, and >0 if an error occurs.
