+=========================
+Some bug fixes & minor enhancements, including:
+  Backwards compatibility with LVM1 metadata improved.
+  Missing man pages written.
+  Tool error codes made more consistent.
+  vgmknodes written.
+  O_DIRECT can be turned off if it doesn't work in your kernel.
+  dumpconfig to display the active configuration file

+You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
+If your root filesystem is on an LV, you should run one of those two
+commands to fix up the special files in /dev in your real root filesystem 
+after finishing with your initrd.  Also, remember you can use
+'vgchange --ignorelockingfailure' on your initrd if the tool fails because
+it can't write a lock file to a read-only filesystem.

 .SH DESCRIPTION
 dmsetup manages logical devices that use the device-mapper driver.  
 Devices are created by loading a table that specifies a target for
-each sector in the logical device.
+each sector (512 bytes) in the logical device.
 
 The first argument to dmsetup is a command. 
 The second argument is the logical device name or uuid.
+.SH OPTIONS
+.IP \fB-j|--major\ \fImajor
+.br
+Specify the major number to use on creation.
+.IP \fB-j|--minor\ \fIminor
+.br
+Specify the minor number to use on creation.
+.IP \fB-r|--readonly
+.br
+Set the table being loaded read-only.
+.IP \fB-v|--verbose [-v|--verbose]
+.br
+Produce additional output.
+.IP \fB--version
+.br
+Display the library and kernel driver version.
 .SH COMMANDS
 .IP \fBcreate
-.I device_name table_file [uuid]
+.I device_name [-u uuid] [--notable] [table_file]
 .br
-Attempts to create a device using the table file given.
+Creates a device with the given name.
+If table_file is supplied, the table is loaded and made live.
+Otherwise a table is read from standard input unless --notable is used.
 The optional uuid can be used in place of
-device_name in subsequent dmsetup commands.  If
-successful a device will appear as
-/dev/device-mapper/<device-name>.  See below for information
-on the table file format.
+device_name in subsequent dmsetup commands.  
+If successful a device will appear as
+/dev/device-mapper/<device-name>.  
+See below for information on the table format.
+.IP \fBdeps
+.I device_name
+.br
+Outputs a list of (major, minor) pairs for devices referenced by the
+live table for the specified device.
+.IP \fBinfo
+.I device_name
+.br
+Outputs some brief information about the device in the form:
+.br
+    State: SUSPENDED|ACTIVE, READ-ONLY
+.br
+    Tables present: LIVE and/or INACTIVE
+.br
+    Open reference count
+.br
+    Last event sequence number (used by \fBwait\fP)
+.br
+    Major and minor device number
+.br
+    Number of targets in the live table
+.br
+    UUID
+.IP \fBls
+.br
+List device names.
+.IP \fBload|reload
+.I device_name [table_file]
+.br
+Loads table_file into the inactive table slot for device_name.
+If table_file is not supplied, reads a table from standard input.
 .IP \fBremove
 .I device_name
 .br
-Removes a device
+Removes a device.  It will no longer be visible to dmsetup and
+will be deleted when its open_count is zero.
+.IP \fBremove_all
+.br
+Attempts to remove all device definitions i.e. reset the driver.
+Use with care!
 .IP \fBrename
 .I device_name new_name
 .br
-Renames a device
+Renames a device.
+.IP \fBresume
+.I device_name
+.br
+Un-suspends a device.  
+If an inactive table has been loaded, it becomes live.
+Postponed I/O then gets re-queued for processing.
+.IP \fBstatus
+.I device_name
+.br
+Outputs status information for each of the device's targets.
 .IP \fBsuspend
 .I device_name
 .br
 Suspends a device.  Any I/O that has already been mapped by the device
 but has not yet completed will be flushed.  Any further I/O to that
 device will be postponed for as long as the device is suspended.
-.IP \fBresume
-.I device_name

-back in using the create or reload commands.
-.IP \fBwait

 Each line of the table specifies a single target and is of the form:

 There are currently three simple target types available together 
 with more complex optional ones that implement snapshots and mirrors.
