+cdist-type__filesystem(7)
+=========================
+
+NAME
+----
+cdist-type__filesystem - Create Filesystems.
+
+
+DESCRIPTION
+-----------
+This cdist type allows you to create filesystems on devices.
+
+If the device is mounted on target, it refuses to do someting.
+
+If the device has a filesystem other as the specified and/or
+  the label is not correct, it only make a new filesystem 
+  if you specified --force option
+
+
+REQUIRED PARAMETERS
+-------------------
+fstype
+    Filesystem type, for example 'ext3', 'btrfs' or 'xfs'
+
+blkdev
+    Blockdevice for filesystem,
+    On linux, it can be any by lsblk accepted device notation 
+    
+    for example 
+        /dev/sdx 
+        or /dev/disk/by-xxxx/xxx
+        or /dev/mapper/xxxx
+
+
+OPTIONAL PARAMETERS
+-------------------
+label
+   Label which sould apply on the filesystem
+
+mkfsoptions
+   Additional options which are inserted to the mkfs.xxx call.
+
+
+BOOLEAN PARAMETERS
+------------------
+force
+   Normaly, this type does nothing if a filesystem is found
+   on the target device. If you specify force, its formated
+   if the filesystem type or label differs from parameters
+   Warning: This option can easy lead into data loss !
+
+MESSAGES
+--------
+filesystem <fstype> on <blkdev> : <discoverd device> created
+   Filesytem was created on <discoverd device>
+
+
+EXAMPLES
+--------
+
+.. code-block:: sh
+
+    # Ensures that device /dev/sdb is formated with xfs 
+    __filesystem dev_sdb --fstype xfs --blkdev /dev/sdb --label Testdisk1
+    # The same thing with btrfs and disk spezified by pci path to disk 1:0 on vmware
+    __filesystem dev_sdb --fstype btrfs --blkdev /dev/disk/by-path/pci-0000:0b:00.0-scsi-0:0:0:0 --label Testdisk2
+    # Make sure that a multipath san device has a filesystem ...
+    __filesystem dev_sdb --fstype xfs --blkdev /dev/mapper/360060e80432f560050202f22000023ff --label Testdisk3
