Description Zdenek Kabelac 2017-08-01 18:40:25 EDT
Description of problem:

When 'lvconvert -m+1  vg/lv' is used to upconvert LV to raid1 it looks like 'resync' with older kernels.

status reports  'aa  X/Y resync' and such operation is evauluated as
'extreactable' via function  _raid_allow_extraction().

So in such case it has lost the meaning of 'origin' and replica-leg
and user is allowed to 'remove'  1st. (origin) leg.

Observable on Fedora 19, RH6...
