Code path missed validation of lvcreate --cachepool argument.
If the non cache-pool LV was passed in, code has still continued
further work and failed later on internal error. Validate this
condition at right place now.
Trap cases where the percentage calculation currently leads to an empty
LV and the message:
Internal error: Unable to create new logical volume with no extents
Additionally convert the calculated number of extents from physical to
logical when creating a mirror using a percentage that is based on
Physical Extents. Otherwise a command like 'lvcreate -m3 -l80%FREE'
can never leave any free space.
This brings the behaviour closer to that of lvresize.
(A further patch is needed to cover all the raid types.)
As now we can properly recognize all paramerters for pool creation,
we may drop PASS_ARG_ defines and rely on '_UNSELECTED' or 0 entries
as being those without user given args.
When setting are not given on command line - 'update' function
fill them from profiles or configuration. For this 'profile' arg
was needed to be passed around and since 'VG' itself is not needed,
it's been all replaced with 'cmd, profile, extents_size' args.
To more easily recognize unselected state from select '0' state
add new 'THIN_ZERO_UNSELECTED' enum.
Same applies to THIN_DISCARDS_UNSELECTED.
For those we no longer need to use PASS_ARG_ZERO or PASS_ARG_DISCARDS.
Check for dm-raid target version with non-standard raid4 mapping expecting the dedicated
parity device in the last rather than the first slot and prohibit to create, activate or
convert to such LVs from striped/raid0* or vice-versa in order to avoid data corruption.
Add related tests to lvconvert-raid-takeover.sh

If the number of stripes requested is incompatible with the requested
type of raid, give an error instead of adjusting it.
If no stripes argument is supplied, continue to use an appropriate
default.
Creating a RaidLV in VGs with very small extent sizes caused
late failure in the kernel giving a not very informative error
message. Catch the attempt early and display failure message
'Unable to create RAID LV: requires minimum VG extent size 4.00 KiB'.

Enforce mirror/raid0/1/10/4/5/6 type specific maximum images when
creating LVs or converting them from mirror <-> raid1.
Document those maxima in the lvcreate/lvconvert man pages.

The MD raid6 personality being used to drive lvm raid6 LVs does
read-modify-write updates to any stripes and thus relies on correct
P and Q Syndromes being written during initial synchronization or
it may fail reconstructing proper user data in case of SubLVs failing.
We may not allow the '--nosync' option on
creation of raid6 LVs for that reason.
Update/fix 'man lvcreate' in that regard.
add lvcreate-raid-nosync.sh test script.

General RAID and RAID segment type specific checks are added
to merge.c. New static _check_raid_seg() is called on each segment
of a RaidLV (which have just one) from check_lv_segments().
New checks caught some unititialized segment members
which are addressed here as well:
- initialize seg->region_size to 0 in lvcreate.c for raid0/raid0_meta
- initialize list seg->origin_list in lv_manip.c
Commit 3928c96a37 introduced
new defaults for raid number of stripes, which may cause
backwards compatibility issues with customer scripts.
Adding configurable option 'raid_stripe_all_devices' defaulting
to '0' (i.e. off = new behaviour) to select the old behaviour
of using all PVs in the VG or those provided on the command line.
In case any scripts rely on the old behaviour, just set
'raid_strip_all_devices = 1'.

raid0/raid0_meta type LVs don't have a default number of stripes when
created without '-i/--stripes Stripes' whereas other raid types have one.
Patch sets the default for raid0/raid0_meta to 2 stripes.
The default amount of stripes for raid4/5/10 is changed to 2 and for raid6 to 3
rather than using all PVs in the VG or those provided on the command line.
This is to avoid unintended high number of stripes in case of many PVs.
To select a different amount of stripes from the default,
use 'lvcreate -i/--stripes Stripes'.

The lvm fullreport works per VG and as such, the vg, lv, pv, seg and
pvseg subreport is done for each VG. However, if the PV is not part of
any VG yet, we still want to display pv and pvseg subreports for these
"orphan" PVs - so enable this for lvm fullreport's process_each_vg call.
If there's parent processing handle, we don't need to create completely
new report group and status report - we'll just reuse the one already
initialized for the parent.
Currently, the situation where this matter is when doing internal report
to do the selection for processing commands where we have parent processing
handle for the command itself and processing handle for the selection
part (that is selection for non-reporting tools).
This is hotfix for RHBZ: https://bugzilla.redhat.com/1324537
However already the %FREE is not a good fit and we need something
better. Meanwhile make -l%PVS work at least as good as %FREE
for thin-pool.
TODO: this needs rework - it should be allocator to do all the size
decisions at one place.
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).
Keep policy name separate from policy settings and avoid
to mangling and demangling this string from same config tree.
Ensure policy_name is always defined.
... 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!)
