a631fa20d0 cache: disallow stripes/size for cache pool
ATM allocation can't handle stripping and cache pool allocation.
It's not yet even clear what should be actually result.
Until resolved, disable this option (it's been coredumping
inside allocation anyway).

3ec4813ba2 coverity: fix missing initialization
... Using uninitialized value "lockd_state" when calling "lockd_vg"
(even though lockd_vg assigns 0 to the lockd_state, but it looks at
previous state of lockd_state just before that so we need to have
that properly initialized!)

libdm/libdm-report.c:2934: uninit_use_in_call: Using uninitialized value "tm". Field "tm.tm_gmtoff" is uninitialized when calling "_get_final_time".

daemons/lvmlockd/lvmlockctl.c:273: uninit_use_in_call: Using uninitialized element of array "r_name" when calling "format_info_r_action". (just added FIXME as this looks unfinished?)

035276ab83 lvcreate: do not silently accept '-m #' with raid4/5/6
If the user provides '-m #' (# > 0) with mappings
raid4/5/6, the command silently creates
'#mirrors * #stripes + #parity' image component pairs.

Patch rejects '-m #' altogether for those mappings
in order to avoid LV creation with unexpected layout.

e0164f2188 sparse: configurable type for sparse volumes
Support compile type configurable defaults for creation
of sparse volumes.

By default now create 'thin-pools' for sparse volumes.
Use the global/sparse_segtype_default to switch back to old
snapshots if needed.

Apply the same compile logic for newly introduces mirror/raid1 options.

c9fbbf48ba cache: support more args
Unlike with thin-pool - with cache we support all args also
directly when create cache volume.

So the result of 'separate' cache-pool creation and setting its
options should give same result as specifying those args
during cache creation.

Cache-pool values are used as defaults if the params are
not specified with cache creation.

784c216d2b lvcreate: check for conflicting -Zy -Wy
Let the finaly state of zero & wipe_signature to be
resolved later together with all the types.

Don't play with zero assigment and segtype flag
(i.e. thin-pool -Z  has different meaning).

Check if the passed options do allow requested zeroing/wiping.

lvcreate without -Z or -W will fallback to warning if the device
cannot be zeroed, however if user requested them explicitely
it will give user error.

d13239b054 lvcreate: new validation code
Refactor lvcreate code.

Prefer to use arg_outside_list_is_set() so we get automatic 'white-list'
validation of supported options with different segment types.

Drop used lp->cache, lp->cache and use seg_is_cache(), seg_is_thin()

Draw clear border where is the last moment we could change create
segment type.

When segment type is given with --type - do not allow it to be changed
later.

Put together tests related to individual segment types.

Finish cache conversion at proper part of lv_manip code after
the vg_metadata are written - so we could correcly clean-up created
stripe LV for cache volume.

0cbb381e15 lvcreate: regression fix on lv name limits
When we are given an existing LV name - it needs to be allowed
to pass in even restricted name as the LV could have existed
long before we introduced some new restriction on prefix/suffix.i

Fix the regression on name limits and drop restriction to be applied
on any existing LVs - only the new created LV names have to be
complient with current name restrictions.

FIXME: we are currently using restricted names incorrectly in few
other places - device_is_usable() skips restricted names,
and udev flags are also incorrectly set for restricted names
so these LVs are not getting links properly.

d46c2f1c94 cache: improve creation code
Move code to better locations.
Improve test and remove invalid ones
(i.e. no reason to require cache size to be >= then origin).

Correctly comment where the code is doing actual conversion
of other existing volume - we do already a similar thing with
external origins.

Lots of new command line options and combinations is now supported.
Hopefully older syntax still works as well.

lvcreate --cache --cachepool vg/pool  -l1
lvcreate --type cache --cachepool vg/pool  -l1
lvcreate --type cache-pool vg/pool  -l1
lvcreate --type cache-pool --name pool vg  -l1
... and many many more ...

487723e0df lvcreate: refactor code
Over the time lvcreate code has accumulated various hacks.
So try to move that code in right places.

Detect all types early in _lvcreate_params() so functions like
_read_size_params() do not need to change volume types.

Also ultimately respect give volume --type, that its shortcut
(-T, H, -m, -s) and after that options which do type estimation.
(i.e. --cachepool, --thinpool)

Avoid repeative tests - if we know all types are decode at once
place we can 'optimize' number of validations.

17ab39f743 cache: include cache mode in vg metadata and display
The cache mode of a new cache pool is always explicitly
included in the vg metadata.  If a cache mode is not
specified on the command line, the cache mode is taken
from lvm.conf allocation/cache_pool_cachemode, which
defaults to "writethrough".

The cache mode can be displayed with lvs -o+cachemode.
