lvconvert testing is now in its own test, t-lvconvert-mirror-basic ... it
doesn't do anything fancy but it does run lvconvert through a lot of
combinations.
I have also merged the remaining t-mirror-lvconvert tests into
t-lvconvert-mirror and abolished the former. The latter will be split again
later into more thematic divisions. (The previous split was rather arbitrary,
may I even say random...)
Use Requires.private: instead of Libs.private:
Use UDEV_PC and SELINUX_PC for Require.private:
It looks like usage of Requires.private is prefered from Libs.private.
However pkg-config documentation is really poor here. But here is
short outcome:
There is a difference in Libs.private: and Requires.private: where
we specify libselinux instead of -lselinux -lsepol.
We leave resolving of query like 'pkg-config --libs --static devmapper'
on taking proper selinux and udev libs to their .pc files instead of
hardcoding them into our .pc file which is might give incorrect answer.
- i.e. dependency of libselinux package might change and we may return
wrong list of linked libraries.

A shortcut for --ignorelockingfailure, --ignoremonitoring, --poll n options

once in initialisation scripts (e.g. rc.sysinit or initrd).
Target install_dm_plugin installs files to libdir/device-mapper.
Target install_lvm2_plugin installs files to libdir/lvm2.
Both targets creates relative links to libdir to keep the code
compatible with current dlopen handling.
Once we will be able to read plugins from subdir, links
could be removed.
(with table provided).
This remove ioctl generates udev events like any other hence it needs to be
synchronized properly as well. Also, add dm task type in debug log when
setting a cookie (for better debugging).
fails, the test will carry on but will issue a warning. The harness detects
such warnings from tests and marks tests that passed with warnings with a
special status.
We can use it even in read-only environment where a try to initialise
file-based locking fails (not to mention other processing related with
lvm2 init). Simply, we want to output the version only, nothing else.
And this should always work.

The testing code still needs some improvement. I'd like to add
the ability to test specifying the PVs to be added/removed during
a convert. It will also be important to test partial PV
specification during down converts (i.e. request to remove more
mirror images than we have provided PVs for).
This rule appeared in udev v152 and it helps us to support spurious events
where we didn't have any flags set (events originated in udevadm trigger
or the watch rule). These flags are important to direct the rule application.
Now, with the help of this rule, we can regenerate old udev db content.
To implement this correctly, we need to flag all proper DM udev events with
DM_UDEV_PRIMARY_SOURCE_FLAG. That happens automatically for all ioctls
generating events originated in libdevmapper.
being able to remove more images from a mirror than the
number of PVs directly specified for removal.
The effort to fix bug 581611 corrected a bug that was unnoticed
at the time. The loop in _remove_mirror_images that looks over
the specified PVs was allowing devices that were previously
counted and moved to the end of the list to be double-counted.
This resulted in the number of devices needed for removal always
being satisfied - even if the user did not specify enough PVs
for removal to satisfy the request. When 581611 was fixed, this
double-counting no longer took place and the result was to remove
only the minimum of the number of PVs specified or the number
that was asked to be removed.
By simply always setting 'new_area_count' (as used to be done
only in the else statement), we return to the previous behavior.
Indeed, this is exactly what the double-counting was allowing
to happen before the fix of 581611.
Allow lv_remove_with_dependencies() to know the top-level LV that was
requested to be removed (otherwise it recurses and we lose context).
A merging snapshot cannot be removed directly but the associated origin
can be. Disallow removal of a merging snapshot unless the associated
origin is also being removed.
