8daf5cd45f 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

  lvconvert --type cache --cachepool LV LV_linear_striped_thinpool_vdo_vdopool_vdopooldata_raid

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.

353718785f man: typography
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)

Use automatic enumeration for .SH titles.

Guidelines in-use:

87a3ea7f8f Revert "thinpool: support lvconvert without zeroing"
This reverts commit 8e7690b798.

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.

section .nh ... .hy.

ATM global _was_hyphen is used to properly finish sections after

01f108c4d0 tests: skip autoactivation-metadata with lvmlockd
shared vgs are not autoactivated
2021-04-08 16:08:45 -05:00
David Teigland
0a28e3c44b 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.

79a168d119 tests: pvmove updates
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.

fe4f83171d signals: support also SIGTERM for breaking command
If we are signaled with SIGTERM it should be at least as good

So when lvm2 command allows signal handling we also
enable SIGTERM handling. If there are some other signals
we should handle equally -  we could just extend array.
