1) When converting from an x-way mirror/raid1 to a y-way mirror/raid1,
the default behaviour should be to stay the same segment type.
2) When converting from linear to mirror or raid1, the default behaviour
should honor the mirror_segtype_default.
3) When converting and the '--type' argument is specified, the '--type'
argument should be honored.
catch such conditions, but errors in the tests caused the issue to go
unnoticed. The code has been fixed to perform #2 properly, the tests
have been corrected to properly test for #2, and a few other tests
were changed to explicitly specify the '--type mirror' when necessary.
In those places where mirrors were being created while assuming
a default segment type of "mirror", we include the '--type mirror'
argument to explicitly set the segment type. This will preserve
the mirror testing that is performed even though the default
mirroring segment type is now "raid1".
If the user would upconvert a linear LV to a mirror without specifying
the segment type ("--type mirror" vs "--type raid1"), the "mirror"
segment type would be chosen without consulting the 'default_mirror_segtype'
setting in lvm.conf. This is now used as the basis for determining
which should be used if left unspecified.
When reformatting the 'lvchange_resync' code in commit
05131f5853, a '!' should have been removed
from the condition that checks for the LV_NOTSYNCED flag on a corelog
mirror LV. The presence of this '!' caused the LV_NOTSYNCED flag to be
cleared when it wasn't present and left when it was present.
It is not allowed to add images to a 'mirror' or 'raid1' LV if the
LV_NOTSYNCED flag is set. We add some up-convert tests to ensure this
behavior is being enforced and that the LV_NOTSYNCED flag is being
properly cleared by 'lvchange --resync'.
(Not updating WHATS_NEW because this is intrarelease.)
When mirrors are up-converted, a transient mirror layer is put in so that
only the new devices are sync'ed. That transient layer must carry the tags
of the original mirror LV, otherwise it will fail to activate when activation
is regulated by lvm.conf:activation/volume_list. The conversion would then
fail.
The fix is to do exactly the same thing that is being done for linear ->
mirror converting (lib/metadata/mirror.c:_init_mirror_log()). We copy the
tags temporarily for the new LV and remove them after the activation.

Shell improvements - use internal function for checks
Use PVs in "" (LV and VG cannot have spaces)
Several test very starting 'dmeventd' without annoucing
it via prepade_dmeventd.
Fix some of test actually.
Reduce disc excercise for some test and focus on LVM testing by
using smaller extent size.
Reduce number of teardown_devs calls and use vg/lvremove instead.
Don't sleep for seconds on pvmove.
FIXME: shell/lvconvert-mirror-basic.sh seems to need more checking.
Test fails for smalled extent size then 512k.
