CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	jbrassow@sourceware.org	2007-08-29 20:19:11

Modified files:
	lib/metadata   : mirror.c 
	tools          : lvconvert.c 

Log message:
	When mirrors are created with the --nosync option, a status flag
	(MIRROR_NOTSYNCED) is added to the LVM metadata.  This flag is
	not cleared when converting to linear.  Subsequently, if you
	up-convert the linear to a mirror, the flag remains - even though
	an up-convert will always force a complete resync.
