As a follow-up of irc discussion.
incorrect filter rules were set.
For drbd its mandatory to let lvm2 command see only those devices which are
supposed to be used.
Reference to drbd lvm nesting guide:
http://www.drbd.org/users-guide-8.3/s-nested-lvm.html
Rule #1 - set an appropriate 'filter' is very important.
For activation of nested LV lvm must not see drbd origin nodes!
