 - first_seg
 - lv_status
 - lv_status_r
 - lv_is_mirrored
 - seg_item
 - seg_status
 - segs_using_this_lv

You can get a list of these user-defined commands by typing:

bc773e60e1 Add "dmsetup ls --tree" output to lvmdump.
It would be most useful to add "dmsetup ls --tree" to the commands run.
This command helps in answering the question "which devices are actually
underneath a given LV?"

Although the info is available with other existing dmsetup commands,
adding this command gives a much clearer summary of complex setups.

Here's an example of an LVM mirror, with mirror images on partitions
created on top of multipath devices.  The multipath devices are on
simple block devices.  As you can see, it is easy to see the stacking
from the "dmsetup ls --tree" output:

vgmpathtest-lvmpathmir (253:14)
 ├─vgmpathtest-lvmpathmir_mimage_1 (253:13)
 │  └─mpath5p1 (253:5)
 │     └─mpath5 (253:2)
 │        ├─ (8:16)
 │        └─ (8:0)
 ├─vgmpathtest-lvmpathmir_mimage_0 (253:12)
 │  └─mpath6p1 (253:6)
 │     └─mpath6 (253:3)
 │        ├─ (8:48)
 │        └─ (8:32)
 └─vgmpathtest-lvmpathmir_mlog (253:11)
    └─mpath7 (253:4)
       ├─ (8:80)
       └─ (8:64)
VolGroup00-LogVol01 (253:1)
 └─ (202:2)
vgtest-lvmir (253:10)
 ├─vgtest-lvmir_mimage_1 (253:9)
 │  └─ (7:1)
 ├─vgtest-lvmir_mimage_0 (253:8)
 │  └─ (7:0)
 └─vgtest-lvmir_mlog (253:7)
    └─ (7:3)
VolGroup00-LogVol00 (253:0)
 └─ (202:2)

But it is much harder to see the stacking with only the commands today
("dmsetup info", "dmsetup status", and "dmsetup table").  We could
piece together the stacking from "dmsetup table" but it requires
further processing (take output from "dmsetup info to get
map name to major/minor, then parse "dmsetup table", etc).

a9d6333bd6 fsadm fix for downsize of unmounted fs
Fix for the last commit as $MOUNTED is not only used as bool flag,
but also store mounted location for remount - so parsing output
from mount differently then from /proc/mounts.

Prefix calls of 'tunefs' tools with LANG=C to be sure we always do get
some nonlocalized strings.

Avoid using forced 'resize2fs' for cleanly unmounted filesystems and
run regular fsck -f for this case as required by resize2fs.

'fsadm check' uses date difference for extX filesystems between
the last mount and last check of 'fsck -f' execution and if the mount
was later run 'fsck' with -f so resize2fs is happy and user does not
need to pass '-f' flag.

b500eddad1 Scan also 'mount' output for mounted filesystem.
As util-linux package seems to give all the time different names,
try harder to figure out, where is the given lv possible mounted
and scan /proc/mounts and if not found there, test also 'mount' output.

/dev/dm-xxx
/dev/mapper/vg-lv
/dev/vg/lv

All of them could be used different combination in /proc/mount and mount output.

Patch fixes regression for older systems where new detection code failed to
find valid combination.

User needs to 'configure --enable-ocf' to get file installed
by 'make install' target by default.
User can also use 'make install_ocf' to get only ocf files installed.
With disabled (default) ocf support - no ocf files are installed.

55b94bf393 Fix detection of mounted filesystem.
Update the way how fsadm detects mounted filesystem.
With udev /dev/dm-XXX paths are now returned - but mount or /proc/mounts
prints names in form of /dev/mapper/vg-lv - so the match was not found.
Fixex RHBZ #638050.

Current solution uses same trick as mount and detects vg-lv name through
/sys where available - this should be reasonable safe.

Instead of calling mount without parameter to get actual mount table,
switch to use /proc/mounts directly.

829fe014a5 Fix a serious bug in the behavior of fasdm tool when breaked.
Under certain conditions it was possible to break (^C) fsadm before actually
resizing filesystem, but lvresize which executed fsadm will think resize
was succesful and shrinks partitions with unresized filesystem on it.

Fix by returning error (1) for this case - this stops lvresize from futher
proceding in resize operation.

2565ffad25 Fix clvmd init script return code when executed as non-root user.
clvmd daemon itself does the right thing when invoked as non-root, by
returning 4.

The patch removes the use daemon function from
/etc/rc.d/init.d/functions that´s unnecessary and has th bad habit to
mask the return codes from the real daemon.

Add a simple and generic check to see if clvmd is executed by root or not.

Our stop/reload/restart paths in the init script are complex and not all
the tools involved in the process are guaranteed to return 4 if executed
by non-root against a process that´s running as root (for example kill
-TERM will return -1 and parsing the output to catch the error is
suboptimal at best).

23b059e7b7 INSTALL rules updates
Patch is inspired by Debian's extra patch.

- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target
- prints whole 'install' command during installation instead of less
  informative "Installing  $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols

7a8fa6aaab Add a [--poll {y|n}] flag to vgchange and lvchange to control whether
the background polldaemon is allowed to start.  It can be used
standalone or in conjunction with --refresh or --available y.

Control over when the background polldaemon starts will be particularly
important for snapshot-merge of a root filesystem.

Dracut will be updated to activate all LVs with: --poll n

The lvm2-monitor initscript will start polling with: --poll y

NOTE: Because we currently have no way of knowing if a background
polldaemon is active for a given LV the following limitations exist and
have been deemed acceptable:
1) it is not possible to stop an active polldaemon; so the lvm2-monitor
   initscript doesn't stop running polldaemon(s)
2) redundant polldaemon instances will be started for all specified LVs
   if vgchange or lvchange are repeatedly used with '--poll y'
