Before leaving _activate_lvs_in_vg() wait till devices
are active - so we do not print message about active
devices earlier then it really happens for a user.
More validations before any thin or cache related conversion begins.
We allow to use and stack:
pool data: cache or raid
pool metadata: raid
pool: linear, striped
cache: linear, striped, raid
thin(extorig): linear, origin, cow, virtual, thin
We use adjusted_mirror_region_size() in two different contexts.
Either on command line -
here we do want to inform user about reduction of size.
Or in pvmove activation context -
here we should only use 'verbose' info.
Do not let fly metadata with just 'minor' set
(since they would not be readable on older version)
Be permissive with invalid major/minor number and
just report them as problem, but allow to use
such metadata with default major:minor.
We do not need to restore LV content on error path - since
for reactivation we always use ondisk/commited metadata,
so passed data are never used.
Drop some unneded extra message, since the called function
repeated logs same info.
Move common code for reading and processing
of --persistent arguments for lvcreate and lvchange
into lvmcmdline.
Reuse validate_major_minor() routine for validation.
Don't blindly activate LVs after change in cluster
and instead only local reactivation is supported.
(we have now many limited targets now).
Dropping 'sigint_caught()' handling, since
prompt() is resolving this case itself.
If we want to support conversion of VG to clustered type,
we currently need to relock active LV to get proper DLM lock.
So add extra loop after change of VG clustered attribute
to exlusively activate all active top level LVs.
When doing change -cy -> -cn we should validate LVs are not
active on other cluster nodes - we could be sure about this only
when with local exclusive activation - for other types
we require user to deactivate volumes first.
As a workaround for this limitation there is always
locking_type = 0 which amongs other skip the detection
of active LVs.
FIXME:
clvmd should handle looks for cluster locking type all the time.
Failure to copy the 'feature_flags' lvconvert_param to the matching
lv_segment field meant that when a user specified the cachemode argument,
the request was not honored.
Try to enforce consistent macro usage along these lines:
lv_is_mirror - mirror that uses the original dm-raid1 implementation
(segment type "mirror")
lv_is_mirror_type - also includes internal mirror image and log LVs
lv_is_raid - raid volume that uses the new dm-raid implementation
(segment type "raid")
lv_is_raid_type - also includes internal raid image / log / metadata LVs
lv_is_mirrored - LV is mirrored using either kernel implementation
(excludes non-mirror modes like raid5 etc.)
lv_is_pvmove - internal pvmove volume
Use lv_is_* macros throughout the code base, introducing
lv_is_pvmove, lv_is_locked, lv_is_converting and lv_is_merging.
lv_is_mirror_type no longer includes pvmove.
This message should be printed only for activation commands,
however since the handling of this flag is not correct
(rhbz 1140029) and will require further changes,
do now just a minor change and switch message into log_debug
(so it's not printed i.e. with every 'lvs -v')
Use lv_update_and_reload() and lv_update_and_reload_origin()
to handle write/suspend/commit/resume sequence.
In few places this properly handle vg_revert() after suspend failure,
and also ensures there is metadata backup after successful vg_commit().
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.
