f88f5a1ca3 thin: move alloc_pool_metadata
Move function from /tool to /lib to thin_manip.c
Since lvm2api will need to move many things into /lib anyway.

	allocation/thin_pool_chunk_size
	activation/thin_pool_autoextend_threshold

a81a2406f1 tools: add common lv_change_activate
Move common code for changing activation state from
vgchange and lvchange to one function.

Fix the order of checks - so we always implicitelly
activate snapshots and thin volumes in exclusive mode,
and we do not allow local deactivation for them.

b36a776a7f thin: move update_pool_params
Now we may recongnize preset arguments, move
the code for updating thin pool related values
into /lib portion of the code.

f06dd8725a thin: mark passed args
Keep the flag whether given thin pool argument has been given on command
line or it's been 'estimated'

Call of update_pool_params() must not change cmdline given args and
needs to know this info.

Since there is a need to move this update function into /lib, we cannot
use arg_count().

FIXME: we need some generic mechanism here.

f4137640f6 thin: add common pool functions
Move common functions for lvcreate and lvconvert.

get_pool_params() - read thin pool args.
update_pool_params() - updates/validates some thin args.

It is getting complicated and even few more things will be
implemented, so to avoid reimplementing things differently
in lvcreate and lvconvert  code has been splitted
into 2 common functions that allow some future extension.

d81498a824 Initialize dmeventd monitoring for every command
Read lvm.conf setting for monitoring for each command. So we should not
activate monitoring if the default compilation is set to monitor during
lvconvert commnads.

Patch also removes check for  clustered VG and allows to disable monitoring
for clustered VG with the assumption, the problem with monitoring and dmeventd
flag passing for INGNORE is already fixed.

aec2115410 Const fixing
Fixing some const warnings - with API change in:

int vg_extend(struct volume_group *vg, int pv_count, const char *const *pv_names,

Change is needed - as lvm2api expects const behaviour here.
So vg_extend() is doing local strdup for unescaping.

skip_dev_dir return const char* from const char* vg_name.

Rest of the patch is cleanup of related warnings.

Also using dm_report_filed_string() API change to simplify
casting in _string_disp and _lvname_disp.

04a6dd7731 API change for args of process_each_lv_in_vg()
Patch adds failed_lvnames to the list of parameters for process_each_lv_in_vg().
If the list is not NULL it will be filled with LV names of failing LVs
during function execution.

Application could later reiterate only on failed LVs.

b73c18242e Do not allow {vg|lv}change --ignoremonitoring if on clustered VG.
clvmd does not propagate DMEVENTD_MONITOR_IGNORE.

Update get_activation_monitoring_mode() to check if the VG that the
LV is being activated in is clustered.  If so, skip it.

Any get_activation_monitoring_mode() error will cause the associated LV
(or VG) to be skipped during activation.  Both vgchange_single() and
lvchange_single(), which call get_activation_monitoring_mode(), are
called by their respective process_each_..() method.

a6bc975a24 Improve activation monitoring option processing
. Add "monitoring" option to "activation" section of lvm.conf
. Have clvmd consult the lvm.conf "activation/monitoring" too.
. Introduce toollib.c:get_activation_monitoring_mode().
. Error out when both --monitor and --ignoremonitoring are provided.
. Add --monitor and --ignoremonitoring support to lvcreate.  Update
  lvcreate man page accordingly.
. Clarify that '--monitor' controls the start and stop of monitoring in
  the {vg,lv}change man pages.

Sun May  3 12:32:30 CEST 2009  Petr Rockai <me@mornfall.net>
  * Rework the toollib interface (process_each_*) on top of new vg_read.

Rebased 6/26/09 by Dave W.

66086ce962 Fix double releasing of vg when repairing of vg is requested.
Several commands calls process_each_vg() and in provided
callback it explicitly recovers VG if inconsistent.
(vgchange, vgconvert, vgscan)

It means that old VG is released and reread  but the function
above (process_one_vg) tries to unlock and release old VG.

Patch moves the repair logic into _process_one_vg() function.

It always tries to read vg (even inconsistent) and then decides
what to do according new defined parameter.

Also patch unifies inconsistent error messages.

The only slight change if for vgremove command, where
it now tries to repair VG before it removes if force arg is given.
(It works similar way before, just the order of operation changed).

ea0cdd28c1 Separate PV label attributes which do not need parse metadata when reporting.
When reporting explicitly label attributes (pv_uuid for example), we do not
need to read metadata.

This patch separate the label fileds and removes scan_vgs_for_pvs
in process_each_pv() if not needed.

(There should be no user visible change in output.)

25b733809a Merge with text format branch.
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.
