12667e9897 fix check for md raid imsm signature on 4k devices
On devices with 4k logical block size, the imsm signature
is located 8k from the end of the device, not 1k as is
the case for devices with 512 LBS.

a915cd5a46 lvconvert: vdo may convert already formated vdo
User use 'lvconvert -Zn --type vdo-pool' to convert an existing
vdo formated volume and skip lvm2 internal formating.
This however requires user is passing proper matching parameters.
For them user can use --profile|--metadataprofile option whos
support has been also enhanced.

TODO: add support to read values directly from formated volume.

096edeee71 lv_manip: avoid removing LV when converting
In some cases we use 'creation' also during conversion.
Here it can be actually unwanted side effect we may remove
not just newly created layers - but also original converted LV.

So until we make clear how to properly revert from some errors
in middle of conversion, disable removal for any 'lvconvert' commands.

53666d6ee3 lvconvert: thin errorwhenfull and recalculation
When converting an existing LV to thin-pool,
user may now pass also '--errorwhenfull' option
like with 'lvcreate'.

Also recalculate chunksize when performace profile is
used with conversion (again matching lvcreate).

Adds missing flagging for uncropped metadata sizes.

c94d78f068 scan: wipe filters when dropping scanned data
Fix clearing persistent filter state when clearing all
the state from a label_scan.

label_scan reads devs and saves info in bcache, lvmcache,
and in the persistent filter.  In some uncommon cases, an
lvm command wants to clear all info from a prior label_scan,
and repeat label_scan from scratch.  In these cases, info
in lvmcache, bcache and the persistent filter all need to
be cleared before repeating label_scan.

By missing the persistent filter wiping, outdated persistent
filter info, from a prior label_scan, could cause lvm to
incorrectly filter devices that change between polling intervals.
(i.e. if the device changes in such a way that the filtering
results change.)

A case where lvm wants to do multiple label_scans is a
polling command (like lvconvert --merge), when lvmpolld
has been disabled, so that the command itself needs to
to do repeated polling checks.

pvscan service will no longer auto activate any LVs on appeared PVs.
