Giving the special device on which the file system lives -may also work, but is obsolete, mainly because it will fail -in case this device was mounted on more than one directory. - -Note that a file system cannot be unmounted when it is `busy' - -for example, when there are open files on it, or when some process -has its working directory there, or when a swap file on it is in use. -The offending process could even be -.B umount -itself - it opens libc, and libc in its turn may open for example -locale files. -A lazy unmount avoids this problem. - -Options for the -.B umount -command: -.TP -.B \-V -Print version and exit. -.TP -.B \-h -Print help message and exit. -.TP -.B \-v -Verbose mode. -.TP -.B \-n -Unmount without writing in -.IR /etc/mtab . -.TP -.B \-r -In case unmounting fails, try to remount read-only. -.TP -.B \-d -In case the unmounted device was a loop device, also -free this loop device. -.TP -.B \-i -Don't call the /sbin/umount.<filesystem> helper even if it exists. By default /sbin/umount.<filesystem> helper is called if one exists. -.TP -.B \-a -All of the file systems described in -.I /etc/mtab -are unmounted. (With -.B umount -version 2.7 and later: the -.I proc -filesystem is not unmounted.) -.TP -.BI \-t " vfstype" -Indicate that the actions should only be taken on file systems of the -specified type. More than one type may be specified in a comma separated -list. The list of file system types can be prefixed with -.B no -to specify the file system types on which no action should be taken. -.TP -.BI \-O " options" -Indicate that the actions should only be taken on file systems with -the specified options in -.IR /etc/fstab . -More than one option type may be specified in a comma separated -list. Each option can be prefixed with -.B no -to specify options for which no action should be taken. -.TP -.B \-f -Force unmount (in case of an unreachable NFS system). -(Requires kernel 2.1.116 or later.) -.TP -.B \-l -Lazy unmount. Detach the filesystem from the filesystem hierarchy now, -and cleanup all references to the filesystem as soon as it is not busy -anymore. -(Requires kernel 2.4.11 or later.) -.IP "\fB\-\-no\-canonicalize\fP" -Don't canonicalize paths. For more details about this option see the -.BR mount (8) -man page. -.IP "\fB\-\-fake\fP" -Causes everything to be done except for the actual system call; this -``fakes'' unmounting the filesystem. It can be used to remove -entries from -.I /etc/mtab -that were unmounted earlier with the -n option. - -.SH "THE LOOP DEVICE" -The -.B umount -command will free the loop device (if any) associated -with the mount, in case it finds the option `loop=...' in -.IR /etc/mtab , -or when the \-d option was given. -Any pending loop devices can be freed using `losetup -d', see -.BR losetup (8). - -.SH NOTES -The syntax of external umount helpers is: - -.br -.BI /sbin/umount. <suffix> -.RI { dir | device } -.RB [ \-nlfvr ] -.RB [ \-t -.IR type.subtype ] -.br - -where the <suffix> is filesystem type or a value from "uhelper=" or "helper=" -mtab option. The \-t option is used for filesystems with subtypes support -(for example /sbin/mount.fuse -t fuse.sshfs). - -The uhelper= (unprivileged umount helper) is possible to use when non-root user -wants to umount a mountpoint which is not defined in the /etc/fstab file (e.g -devices mounted by udisk). - -The helper= mount option redirects all umount requests to the -/sbin/umount.<helper> independently on UID. - -.SH FILES -.I /etc/mtab -table of mounted file systems - -.SH "SEE ALSO" -.BR umount (2), -.BR mount (8), -.BR losetup (8). - -.SH HISTORY -A -.B umount -command appeared in Version 6 AT&T UNIX. -.SH AVAILABILITY -The umount command is part of the util-linux package and is available from -ftp://ftp.kernel.org/pub/linux/utils/util-linux/. |
