Copy this file as '.gdbinit' to your home directory or your working
directory. It adds the following commands to gdb:
- 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:
(gdb) help user-defined
You can get more information on each command by typing:
(gdb) help <command>
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:

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).
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.
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.
Updated patch from Florian Haas from Linux-HA project.
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.
FIXME: ocf installation path needs to be kept in sync with pacemaker.
find better way and possible also better location.
Return status code 3 for fsadm check of mounted filesystem - used later with
lvresize update patch to better support online filesystem resize.
Also makes a more consistent user interruption and returns status code 2
in this case.
Try to distinguish between the case of using interactive shell and non
interactive running - different combinations of '-y' and '-p' option
needs to be used for fsck.
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.
Fix missing 'dry' execution of lvresize - fixing problem where resize
command were 'dry-run' executed - but lvresize has been executed for real.
Also adapt code slightly to support better recursive execution of fsadm
through lvresize call.
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.
set appropriate Required-Start and Required-Stop at configure time.
Reorder the checks for user selected cluster managers to match auto
detected ones, to be consistent in the output.
Add special case for qdiskd that´s started after cman/lock_gulmd for
RHEL-4/RHEL-5.
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).

- s/Active clustred VG/clustered VG/ (only LV can be active)
- print only active LVs (not all) in status command
(In the lvdisplay form /dev/vg/lv.)
For now, still use awk (already used in clustered_vgs).

length(array) is specific to GNU awk and doesn't work in mawk.
Use a return value of "split" function to indicate array size, this is
supported in both gawk and mawk.
This patch fixes the following errors during "make install" when mawk is
installed as a default awk.

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
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
- increase timeout to 30 secs (on Chrissie request)
- source both cluster and clvmd for options (like all the other cluster
init scripts)
- add clustered_vgs and _lvs commodity fns
- move rh_status* fns at the top, so they can be reused
- heavily cleanup start and stop fns from redundant code and unnecessary
loops
- improve output from different operations
- make the init script lsb compliant
- don´t force kill of the daemon, send only a TERM signal and then wait
for it to exit
- Resolves rhbz#533247
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'
