When testing conversion sanity, we checked lv->status & MIRRORED
which encompasses both old mirrors and raid1 mirrors. But we need to
ban only the old mirrors here hence allow raid1 mirrors.
The lv_type_name function is remnant from old code that reported
only single string for the LV type. LV types are now reported
in a more extended way as keyword list that describe the type
precisely (using lv_layout_and_type fn).
The lv_type_name was used in some error messages to display the
type of the LV so just reinstate the old messages back referencing
the type directly with a string - this is enough for error messages.
They don't need to display the LV type as precisely as it's used
on lvs output (which is optimized for selection anyway).
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.

When ignoring 'listed' volume, print info message.
(So the final command error message is a bit less confusing,
i.e. when user tries to deactive virtual origin:
> lvchange -an vg/lvol2_vorigin
Ignoring virtual origin logical volume vg/lvol2_vorigin.
One or more specified logical volume(s) not found.
_pvcreate_check() has two missing requirements:
After refreshing filters there must be a rescan.
(Otherwise the persistent filter may remain empty.)
After wiping a signature, the filters must be refreshed.
(A device that was previously excluded by the filter due to
its signature might now need to be included.)
If several devices are added at once, the repeated scanning isn't
strictly needed, but we can address that later as part of the command
processing restructuring (by grouping the devices).
Replace the new pvcreate code added by commit
54685c20fc "filters: fix regression caused
by commit e80884cd080cad7e10be4588e3493b9000649426"
with this change to _pvcreate_check().
The filter refresh problem dates back to commit
acb4b5e4de "Fix pvcreate device check."
With cmirrord, we can do pvmove of clustered mirror. The code checking
suitability of LVs on the PV being moved issued a message if a mirror
LV was found and the VG was clustered. However, the actual pvmove did
work correctly.
The top-level mirror LV is actually skipped in the code since it's
always layered on top of internal LVs making up the mirror LV and for pvmove
we consider these internal devices only as they're actually layered on
top of concrete PVs then. But we don't need to issue any message here
about skipping the top-level mirror LV - it's misleading here.
Commit e80884cd08 tried to dump filters
for them to be reevaluated when creating a PV to avoid overwriting
any existing signature that may have been created after last
scan/filtering.
However, we need to call refresh_filters instead of
persistent_filter->dump since dump requires proper rescannig to fill
up the persistent filter again. However, this is true only for pvcreate
but not for vgcreate with PV creation where the scanning happens before
this PV creation and hence the next rescan (if not full scan), does not
fill the persistent filter.
Also, move refresh_filters so that it's called sooner and only for
pvcreate, vgcreate already calls lvmcache_label_scan(cmd, 2) which
then calls refresh_filters itself, so no need to reevaluate this again.
This caused the persistent filter (/etc/lvm/cache/.cache file) to be
wrong and contain only the PV just being processed with
vgcreate <vg_name> <pv_name_to_create>.
This regression caused other block devices to be filtered out in case
the vgcreate with PV creation was used and then the persistent filter
is used by any other LVM command afterwards.
Fix get_pool_params to only read params.
Add poolmetadataspare option to get_pool_params.
Move all profile code into update_pool_params.
Move recalculate code into pool_manip.c
Revert logic and rename new arg_ functions to:
arg_from_list_is_set()
arg_outside_list_is_set()
When err_found is given, log_error message is automaticaly
printed.
Support --repair and --use-policies with mirrors.
(fixes another regression from lvconvert change for thin and cache).
TODO: the code path for mirror needs update.
Major update of lvconvert code to handle cache and thin.
related targets.
Code tries to unify handling of cache and thin pools.
Better supports lvm2 syntax:
lvconvert --type cache --cachepool vg/pool vg/cache
lvconvert --type thin --thinpool vg/pool vg/extorg
lvconvert --type cache-pool vg/pool
lvconvert --type thin-pool vg/pool
as well as:
lvconvert --cache --cachepool vg/pool vg/cache
lvconvert --thin --thinpool vg/pool vg/extorg
lvconvert --cachepool vg/pool
lvconvert --thinpool vg/pool
While catching much more command line errors.
(Yet couple paths still needs more tests)
Detects as much cmdline errors prior opening VG.
Uses single lvconvert_name_params to convert LV names.
Detects as much incompatibilies in VG prior prompting.
Uses single prompt to confirm whole conversion.
TODO: still the code needs fixes...
