While we heavily try to spot arrays that are not yet in-sync,
some kernels tends to block our lvm2 command in kernel,
while we resume these smaller raid arrays even for 5 seconds.
But since the result is not really wrong - report these
check failures only as TEST WARNING.
Missed -l option in man page, although users should prefer
lvresize -r when the also want to do a volume management,
as there they can specify i.e. extents for allocation.
Also mention dm-crypt support in command description.
If the 'act' has been already processed by add_client_result()
it could have been possibly release - so avoid accessin 'act->'
afterward and go for next item directly.
This case happens when i.e. we convert LV to another type,
when we change existing LV into a different type - so change
to debug level and avoid confusing users with message about
Device path not match.
We may eventually enhnace caching code to drop cached info
after taking lock and reading VG.
With commit 0b18c25d934564015402de33e15a267045ed1b8c there
was introduced 'zalloc()' for allocation of outdates pvs,
but no matching 'free()' is present.
Switch to use cmd mempool instead of adding free() code into
several places.

commands: use AUTOTYPE in definitions
If a cmd def implies an LV type without --type
in the required options, then include the implied
type in the cmd def as AUTOTYPE: <type>
instead of including the redundant --type foo
in the OO list of options.
Including an implied --type in the OO list would
often cause multiple cmd defs to potentially be
identical when options were used, and a user
command could match more than one cmd def.
The AUTOTYPE values are listed in man page and
help output as
[ --type foo (implied) ]
If a user command includes --type, it will usually
match a cmd def with --type in the required options.
But, if the user command matches a cmd def with
AUTOTYPE, then the specifed --type and AUTOTYPE must
match.
The man-generator program has a new --check
option that compares cmd defs to find any cmd defs
that are equivalent with the use of options,
and should have their options adjusted.
Correcting some usage of Bold and Italics (files).
Adding some missing SEE ALSO.
Fixing missed replaceable paths that are configurable.
Be careful about .P in .TP sections - need to use .sp for space line.
Use .UR/.UE for URL references.
Add missing VG into description of thin pool creation command.
Remove one duplicated thin-pool creation command.
Remove options --discards and --errorwhenfull from the list when the command describes
only creation of a thin volume - as these options do apply for thin-pool.
Also use here more correct name OO_LVCONVERT_THINPOOL instead of OO_LVCONVERT_THIN.
Reorder extra options for cache & thin-pool before common pool options.
Order consistenly --stripes and --stripesize after --extents option
so the options related to pools are better together.
Remove invalid snapshot creation description - since this case is
handled through our configurable spare volume creation.
Add some missing optional --type parameters for few command instancies.
Emit .ad l / .ad b less frequently around larger blocks
we want to keep left aligned.
Avoid emittting empty lines.
Reduce .HP usage and replace it with .TP.
However keep .HP for all option listings, as i.e. html rendering
can't handle well combintion of .TP an .HP together and .TP alone
is not indenting 2nd. line of long option line.
(For .TP line we don't need to emit .br)
Surround .SH with dots for better look.
For some .TP use plain more readable .I for a line.
Support rendering of optional [Number] (for --units).
Use better markup for units and instead of long markup string,
show individual units with markup.
Enhance man typography decoration of optional option
prefixes like --[raid]writebeind and use regular font to render []
as these are not part of the option name itself.

man/help: change LV type listing
Previously, accepted LV types were presented as a series of suffixes
after the "LV" on the command line. The addition of many new types
resulted in this becoming too long, e.g
For man pages, move these types from the command line to a new line
dedicated to listing accepted LV types:
lvconvert --type cache --cachepool LV LV1
...
LV1 types: linear striped thinpool vdo vdopool vdopooldata raid
The special "LV1" is used as a reference to avoid confusion
with other LVs that may appear on the command line. There
are currently no commands with more than one typed LV, but
if there are cases with more, then "LV2" could also be used.
For command line usage/-h output, drop the LV types from the
command line specification. The more detailed is not needed
in the help output and can be found in the man page.
With to use .TP where it's easy and doesn't change layout
(since .HP is marked as deprecated) - but .TP is not always perfetc match.
Avoid submitting empty lines to troff and replace them mostly with .P
and use '.' at line start to preserve 'visual' presence of empty line
while editing man page manually when there is no extra space needed.
Fix some markup.
Add some missing SEE ALSO section.
Drop some white-space at end-of-lines.
Improve hyphenation logic so we do not split options.
Use '.IP numbers' only with first one the row (others in row
automatically derive this value)
Actully this was bad idea - to make it on pair.
-Zn for thin-pools is already used - so here user must have
create new pool and swap existing thin-pool metadata into.
So reverting this commit to avoid any possible regression.
It would be complicated to handle ',' alignment after hyphenation
changes ATM, but these commas seems to be there rather unneeded
so remove them and make the man output more clear.

Add metadata-based autoactivation property for VG and LV
The autoactivation property can be specified in lvcreate
or vgcreate for new LVs/VGs, and the property can be changed
by lvchange or vgchange for existing LVs/VGs.
--setautoactivation y|n
enables|disables autoactivation of a VG or LV.
Autoactivation is enabled by default, which is consistent with
past behavior. The disabled state is stored as a new flag
in the VG metadata, and the absence of the flag allows
autoactivation.
If autoactivation is disabled for the VG, then no LVs in the VG
will be autoactivated (the LV autoactivation property will have
no effect.) When autoactivation is enabled for the VG, then
autoactivation can be controlled on individual LVs.
The state of this property can be reported for LVs/VGs using
the "-o autoactivation" option in lvs/vgs commands, which will
report "enabled", or "" for the disabled state.
Previous versions of lvm do not recognize this property. Since
autoactivation is enabled by default, the disabled setting will
have no effect in older lvm versions. If the VG is modified by
older lvm versions, the disabled state will also be dropped from
the metadata.
The autoactivation property is an alternative to using the lvm.conf
auto_activation_volume_list, which is still applied to to VGs/LVs
in addition to the new property.
If VG or LV autoactivation is disabled either in metadata or in
auto_activation_volume_list, it will not be autoactivated.
An autoactivation command will silently skip activating an LV
when the autoactivation property is disabled.
To determine the effective autoactivation behavior for a specific
LV, multiple settings would need to be checked:
the VG autoactivation property, the LV autoactivation property,
the auto_activation_volume_list. The "activation skip" property
would also be relevant, since it applies to both normal and auto
activation.
Switch to plain 'kill' we should no longer need SIGKILL
as polling can be interrupted.
Resolve problem in aux wait_pvmove_lv_ready() that was using
lvm command to check for UUID - but this was interferring with
VG lock and it's been delaying confirmation.
So reducing slow-down of test - so it can run faster.
Enhance handling of interruptions of polling process and lvmpoll daemon.
Daemon should now react much faster on interrups (i.e. shutdown
sequence) and avoid taking lenghty sleep waiting on pvmove signaling.
