"""
Verify that a device is mounted
name
The path to the location where the device is to be mounted
device
The device name, typically the device node, such as ``/dev/sdb1``
or ``UUID=066e0200-2867-4ebe-b9e6-f30026ca2314`` or ``LABEL=DATA``
fstype
The filesystem type, this will be ``xfs``, ``ext2/3/4`` in the case of classic
filesystems, ``fuse`` in the case of fuse mounts, and ``nfs`` in the case of nfs mounts
mkmnt
If the mount point is not present then the state will fail, set ``mkmnt: True``
to create the mount point if it is otherwise not present
opts
A list object of options or a comma delimited list
dump
The dump value to be passed into the fstab, Default is ``0``
pass_num
The pass value to be passed into the fstab, Default is ``0``
config
Set an alternative location for the fstab, Default is ``/etc/fstab``
persist
Set if the mount should be saved in the fstab, Default is ``True``
mount
Set if the mount should be mounted immediately, Default is ``True``
user
The account used to execute the mount; this defaults to the user salt is
running as on the minion
match_on
A name or list of fstab properties on which this state should be applied.
Default is ``auto``, a special value indicating to guess based on fstype.
In general, ``auto`` matches on name for recognized special devices and
device otherwise.
device_name_regex
A list of device exact names or regular expressions which should
not force a remount. For example, glusterfs may be mounted with a
comma-separated list of servers in fstab, but the /proc/self/mountinfo
will show only the first available server.
.. code-block:: jinja
{% set glusterfs_ip_list = ['10.0.0.1', '10.0.0.2', '10.0.0.3'] %}
mount glusterfs volume:
mount.mounted:
- name: /mnt/glusterfs_mount_point
- device: {{ glusterfs_ip_list|join(',') }}:/volume_name
- fstype: glusterfs
- opts: _netdev,rw,defaults,direct-io-mode=disable
- mkmnt: True
- persist: True
- dump: 0
- pass_num: 0
- device_name_regex:
- ({{ glusterfs_ip_list|join('|') }}):/volume_name
.. versionadded:: 2016.11.0
extra_mount_invisible_options
A list of extra options that are not visible through the
``/proc/self/mountinfo`` interface.
If a option is not visible through this interface it will always remount
the device. This option extends the builtin ``mount_invisible_options``
list.
extra_mount_invisible_keys
A list of extra key options that are not visible through the
``/proc/self/mountinfo`` interface.
If a key option is not visible through this interface it will always
remount the device. This option extends the builtin
``mount_invisible_keys`` list.
A good example for a key option is the password option::
password=badsecret
extra_mount_ignore_fs_keys
A dict of filesystem options which should not force a remount. This will update
the internal dictionary. The dict should look like this::
{
'ramfs': ['size']
}
extra_mount_translate_options
A dict of mount options that gets translated when mounted. To prevent a remount
add additional options to the default dictionary. This will update the internal
dictionary. The dictionary should look like this::
{
'tcp': 'proto=tcp',
'udp': 'proto=udp'
}
hidden_opts
A list of mount options that will be ignored when considering a remount
as part of the state application
.. versionadded:: 2015.8.2
bind_mount_copy_active_opts
If set to ``False``, this option disables the default behavior of
copying the options from the bind mount if it was found to be active.
.. versionadded:: 3006.0

name
The name of block device. Can be any valid fs_spec value.
fs_file
Mount point (target) for the filesystem.
fs_vfstype
The type of the filesystem (e.g. ext4, xfs, btrfs, ...)
fs_mntops
The mount options associated with the filesystem. Default is
``defaults``.
fs_freq
Field is used by dump to determine which fs need to be
dumped. Default is ``0``
fs_passno
Field is used by fsck to determine the order in which
filesystem checks are done at boot time. Default is ``0``
fs_mount
Field is used only in AIX systems to determine if the
filesystem will be mounted by ``mount all``
mount_by
Select the final value for fs_spec. Can be [``None``,
``device``, ``label``, ``uuid``, ``partlabel``,
``partuuid``]. If ``None``, the value for fs_spect will be the
parameter ``name``, in other case will search the correct
value based on the device name. For example, for ``uuid``, the
value for fs_spec will be of type 'UUID=xxx' instead of the
device name set in ``name``.
config
Place where the fstab file lives. Default is ``/etc/fstab``
mount
Set if the mount should be mounted immediately. Default is
``True``
match_on
A name or list of fstab properties on which this state should
be applied. Default is ``auto``, a special value indicating
to guess based on fstype. In general, ``auto`` matches on
name for recognized special devices and device otherwise.
not_change
By default, if the entry is found in the fstab file but is
different from the expected content (like different options),
the entry will be replaced with the correct content. If this
parameter is set to ``True`` and the line is found, the
original content will be preserved.
