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.

95df06d721 man: lvmthin should use clearer thin pool options
Previously, this was the recommended form for creating a thin pool:

lvconvert --thinpool VG/ThinDataLV --poolmetadata VG/ThinMetaLV

but this is confusing, because --thinpool does not actually take
an arg, and is more naturally used to specify an existing thin pool.

The new recommended form is:

lvconvert --type thin-pool --poolmetadata VG/ThinMetaLV VG/ThinDataLV

42e07d2bce dmsetup: Support remove --deferred.
This patch adds a new flag --deferred to dmsetup remove. If this flag is
specified and the device is open, it is scheduled to be deleted on
close.

struct dm_info is extended.

The existing dm_task_get_info() is converted into a wrapper around the
new version dm_task_get_info_with_deferred_remove() so existing binaries
can still use the old smaller structure.

Recompiled code will pick up the new larger structure.

be75076dfc activation: Add "degraded" activation mode
Currently, we have two modes of activation, an unnamed nominal mode
(which I will refer to as "complete") and "partial" mode.  The
"complete" mode requires that a volume group be 'complete' - that
is, no missing PVs.  If there are any missing PVs, no affected LVs
are allowed to activate - even RAID LVs which might be able to
tolerate a failure.  The "partial" mode allows anything to be
activated (or at least attempted).  If a non-redundant LV is
missing a portion of its addressable space due to a device failure,
it will be replaced with an error target.  RAID LVs will either
activate or fail to activate depending on how badly their
redundancy is compromised.

This patch adds a third option, "degraded" mode.  This mode can
be selected via the '--activationmode {complete|degraded|partial}'
option to lvchange/vgchange.  It can also be set in lvm.conf.
The "degraded" activation mode allows RAID LVs with a sufficient
level of redundancy to activate (e.g. a RAID5 LV with one device
failure, a RAID6 with two device failures, or RAID1 with n-1
failures).  RAID LVs with too many device failures are not allowed
to activate - nor are any non-redundant LVs that may have been
affected.  This patch also makes the "degraded" mode the default
activation mode.

The degraded activation mode does not yet work in a cluster.  A
new cluster lock flag (LCK_DEGRADED_MODE) will need to be created
to make that work.  Currently, there is limited space for this
extra flag and I am looking for possible solutions.  One possible
solution is to usurp LCK_CONVERT, as it is not used.  When the
locking_type is 3, the degraded mode flag simply gets dropped and
the old ("complete") behavior is exhibited.

da545ce3b4 tools: add --binary arg to pvs,vgs,lvs and {pv,vg,lv}display -C and report/binary_values_as_numeric lvm.conf option
The --binary option, if used, causes all the binary values reported
in reporting commands to be displayed as "0" or "1" instead of descriptive
literal values (value "unknown" is still used for values that could not be
determined).

Also, add report/binary_values_as_numeric lvm.conf option with the same
functionality as the --binary option (the --binary option prevails
if both --binary cmd option and report/binary_values_as_numeric lvm.conf
option is used at the same time). The report/binary_values_as_numeric is
also profilable.

This makes it easier to use and check lvm reporting command output in scripts.
