6f408f68d2 man: updates to lvmlockd
- remove reference to locking_type which is no longer used
- remove references to adopting locks which has been disabled
- move some sanlock-specific info out of a general section
- remove info about doing automatic lockstart by the system
  since this was never used (the resource agent does it)
- replace info about lvextend and manual refresh under gfs2
  with a description about the automatic remote refresh

c33770c02d lvmlockd: do not allow mirror LV to be activated shared
This reverts 518a8e8cfb
  "lvmlockd: activate mirror LVs in shared mode with cmirrord"

because while activating a mirror LV with cmirrord worked,
changes to the active cmirror did not work.

a9eaab6beb Use "cachevol" to refer to cache on a single LV
and "cachepool" to refer to a cache on a cache pool object.

The problem was that the --cachepool option was being used
to refer to both a cache pool object, and to a standard LV
used for caching.  This could be somewhat confusing, and it
made it less clear when each kind would be used.  By
separating them, it's clear when a cachepool or a cachevol
should be used.

Previously:

- lvm would use the cache pool approach when the user passed
  a cache-pool LV to the --cachepool option.

- lvm would use the cache vol approach when the user passed
  a standard LV in the --cachepool option.

Now:

- lvm will always use the cache pool approach when the user
  uses the --cachepool option.

- lvm will always use the cache vol approach when the user
  uses the --cachevol option.

fdd612b824 generators: avoid contacting syslog with generators
The systemd generators are executed very early during the switch
from initramfs to system partition and the syslog is not yet fully
operational - it may cause blocking, if some debug logging is enabled
at the same time in /etc/lvm/lvm.conf log{} section.

To avoid timeouting and killing this generator - rather enhance lvm
code to suppress any syslog communication when LVM_SUPPRESS_SYSLOG
envvar is set.

Use of this envvar is needed since the parsing of i.e. cmdline options
that could eventually override lvm.conf setting happens in this case
way too late and number of lines could have been already streamed to
syslog.

904e1e3d26 Place the first PE at 1 MiB for all defaults
. When using default settings, this commit should change
  nothing.  The first PE continues to be placed at 1 MiB
  resulting in a metadata area size of 1020 KiB (for
  4K page sizes; slightly smaller for larger page sizes.)

. When default_data_alignment is disabled in lvm.conf,
  align pe_start at 1 MiB, based on a default metadata area
  size that adapts to the page size.  Previously, disabling
  this option would result in mda_size that was too small
  for common use, and produced a 64 KiB aligned pe_start.

. Customized pe_start and mda_size values continue to be
  set as before in lvm.conf and command line.

. Remove the configure option for setting default_data_alignment
  at build time.

. Improve alignment related option descriptions.

. Add section about alignment to pvcreate man page.

Previously, DEFAULT_PVMETADATASIZE was 255 sectors.
However, the fact that the config setting named
"default_data_alignment" has a default value of 1 (MiB)
meant that DEFAULT_PVMETADATASIZE was having no effect.

The metadata area size is the space between the start of
the metadata area (page size offset from the start of the
device) and the first PE (1 MiB by default due to
default_data_alignment 1.)  The result is a 1020 KiB metadata
area on machines with 4KiB page size (1024 KiB - 4 KiB),
and smaller on machines with larger page size.

If default_data_alignment was set to 0 (disabled), then
DEFAULT_PVMETADATASIZE 255 would take effect, and produce a
metadata area that was 188 KiB and pe_start of 192 KiB.
This was too small for common use.

This is fixed by making the default metadata area size a
computed value that matches the value produced by
default_data_alignment.

4b5d6de86b pvscan systemd service for event based activation
The pvscan systemd service for autoactivation was
mistakenly dropped along with the lvmetad related
services.

The activation generator program now looks at the new
lvm.conf setting "event_activation" (default 1) to
switch between event activation and direct activation.

Previously, the old use_lvmetad setting was used to
switch between event and direct activation.

229e63b638 writecache: set block_size using --cachesettings
instead of a separate --writecacheblocksize option.
writecache block_size is not technically a setting,
but it can borrow the option as a special case.

e53cfc6a88 lvmlockd: update method for changing clustered VG
The previous method for forcibly changing a clustered VG
to a local VG involved using -cn and locking_type 0.
Since those options are deprecated, replace it with
the same command used for other forced lock type changes:
vgchange --locktype none --lockopt force.
