CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	mbroz sourceware org	2012-03-23 16:28:41

Modified files:
	.              : WHATS_NEW 
	lib/metadata   : mirror.c 

Log message:
	Fix pvmove if LV is activated exclusively but cmirror is not running.
	
	In this case we should allow to use local mirror, check for cmirror
	should apply only for lvconvert/lvcreate.
	
	Introduced in 2.02.86 by removing !(lv->status & ACTIVATE_EXCL).
	
	(Partially workaround, it is minimalistic patch for now.)
