fc477192e5 cleanup: drop unused code
Code was related to long time obsoleted  vgconvert
for lvm1 to lvm2 conversion.
This code likely was missed to be removed.

edc91caffb thin: external origins across thin-pool
Fix/support creation and usage of the external origin
across thin-pools - so thin LV can use thin LV from
some other thin-pool as external origin (read-only).

27bdd038a8 thin: validate usable volume for external origin
When creating external origin via 'lvcreate --type thin'
add the validation for LV being usable as external origin
since certain LVs cannot be really used this way.
Also call this function early during lvcreate cmdline arg
validation se we do not need to do unecesary operation.

5533f034e2 thin_pool: correct refactoring chunk_size
Function to recalc chunk_size according to dev hints needs to be
used after chunk_size is being set to thin pool segment - correct
this ordering mistake introduced in previous refactoring commit.

9d9e43b87f vdo: correct vdo header size
Previous patch that introduced support for thinpool with vdo
not correctly handled header size - as this part is not fully usable
yet.  We are going to try to use the 0, but current state of code is not
yet compliant to this logic so keep vdo_header_size during conversion
and alos correctly pass through virtual_extents to vdo formating.

db0de73d6e vdo: support creation of compressed thin-pools
Add code to handle creation of  thin-pool with VDO data backend
which can be seen as compressed deduplicated thin-pool.

To avoid need of changing to many internal APIs, pass the conversion
parameters for create thin-pool data volume via cmd_context.

6ec2f1f44b vdo: refactor conversion to vdo lv
Introduce struct vdo_convert_params {} to pass-in all the parameters
needed for the conversion of an LV to a vdopool + vdo LV.

Function convert_vdo_lv() is also able to create a new LV and swap
segments, so the passed in LV can be later on use for futher
conversion so this refactoring makes it ready for more enhanced
usage.

0e4fd4485f lvs: set first attr flag for raid integrity images
The first lv_attr flag is 'i' or 'I' for a raid image.

For integrity raid images (_iorig), the flag was not being set.

e41da923a3 lvconvert: fix "lvconvert -m 0" for in-sync legs
With commit d7e922480e
lvconvert -m   may fail if we try to remove 1st. leg that
is out-of-sync while other leg is in-sync.

Hot fix allows to proceed with such down conversion.

9668d40d5a resize: reduce without prompt for no-fs case
Apply the same logic for 'lvreduce' which exists for newer
systems (compiled with HAVE_BLKID_SUBLKS_FSINFO)
also for older systems for one very common practical case where
the active LV does not have any blkid known signature/filesystem.

New variant recognized this situation and allowed to proceed
without requesting a prompt, while the older variant always
requested confirmation prompt.

With this patch command now works equily for both variants
for 'active LV' without signature and allows to reduce LV
without prompting.

8698f9dce6 pool: use predefined name for metadata LV
While create new LV for pool volume, use name from 'pool_metadata%d' naming
sequence. This LV is later on renamed to  pool_t/cmeta, but if there
is any error in the middle, we may evenutally leave some 'volume',
With this name it can be slightly more obvious how it got there,
but also when we handle _pmspare name - we get slightly more predictible
name used there for it.

However for a standard usage this commit shall no visible impact as the
name is used temporarily just for cleaning LV.

39457234db lvconvert: support conversion to thin volume
Update pool conversion function to handle also conversion of
thick LV to thin LV by moving thick LV into thin pool data LV
and creating fully provissioned thin LV on top of this volume.

Reworking existing conversion to use insert_layer_for_lv co
the uuid is now kept with thin-pool - this should however not
really matter as we are doing full deactivation & activation cycle.

With conversion to thin LV user can use same set of arguments
to set chunk-size.

TODO: add some smart code to decide best values for chunks sizes.

5154054af4 snapshot: no error when extending above max size
When lvm2 calculates the maximal usable COW size and crops the user
requested size to this value, don't return the error result from
the 'lvextend' operation.

We already apply the same logic when resizing thin-pool beyond
the supported maximal size.

FIXME: The return code error logic here is somewhat fuzzy.

6ff65e6755 vdo: check_point_frequence is unused option
This vdo parameter existed in the early stage of integration of vdo into lvm2,
but later it's been removed from vdoformat tool - so actually if
there would be any non-zero value it would cause error on lvcreate.
Option was not stored on disk in lvm2 metadata.

Remove this vdo parameter from lvm2 sources.

(Although this vdo parameter will be still accepted on cmdline through
 --vdosettings option, but it will be ignored.)
