Files are named in a big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. mount serves to attach the file system found on some device to the big file tree. Conversely, umount(8) will detach it again.
invokes verbose mode.
mounts all filesystems (of the given types) mentioned in fstab.
combines with -a. to fork off a new incarnation of mount for each device. This will do the mounts on different devices or different NFS servers in parallel.
causes everything to be done except for the actual system call; if it's not obvious, this `fakes' mounting the file system.
mounts without writing in /etc/mtab. This is necessary for example when /etc is on a read-only file system.
tolerates sloppy mount options rather than failing. This will ignore mount options not supported by a filesystem type. Not all filesystems support this option.
mounts the file system read-only. A synonym is -o ro.
mounts the file system read/write. (default) A synonym is -o rw.
mounts the partition that has the specified label.
mounts the partition that has the specified uuid. These two options require the file /proc/partitions to exist.
indicates a file system type of vfstype.
More than one type may be specified in a comma separated list. The list of file system types can be prefixed with no to specify the file system types on which no action should be taken.
options are specified with a -o flag followed by a comma-separated string of options. Some of these options are only useful when they appear in the /etc/fstab file. The following options apply to any file system that is being mounted:
does all I/O to the file system asynchronously.
updates inode access time for each access. (default)
is mountable with -a.
uses default options: rw, suid, dev, exec, auto, nouser, and async.
interprets character or block special devices on the file system.
permits execution of binaries.
does not update inode access times on this file system.
is only explicitly mountable.
does not interpret character or block special devices on the file system.
does not allow execution of any binaries on the mounted file system.
does not allow set-user-identifier or set-group-identifier bits to take effect.
forbids an ordinary (i.e., non-root) user to mount the file system. (default)
attempts to remount an already-mounted file system. This is commonly used to change the mount flags for a file system, especially to make a read-only file system writable.
mounts the file system read-only.
mounts the file system read-write.
allows set-user-identifier or set-group-identifier bits to take effect.
does all I/O to the file system synchronously.
allows an ordinary user to mount the file system. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line user,exec,dev,suid).
