CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2011-11-15 17:32:12

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

Log message:
	Adjusted mirror region size only for mirrors and raids
	
	Update region_size only for mirror and raid targets.
	This fixes warning messages when vg is using small
	extent size like 1KiB and no mirror/raid is created,
	but the user still got the message:
	
	$> vgcreate -s 1K vg  <pvs>
	$> lvcreate -L10K vg
	Using reduced mirror region size of 4 sectors

 Version 2.02.89 - 
 ==================================
+  Adjusted mirror region size only for mirrors and raids.
   Reorder prompt conditions for removal of active volumes.
   Avoid 'mda inconsistency' by properly registering UNLABELLED_PV flag (2.02.86).
   Fix --enable-static_link unless using --enable-dmeventd / --enable-udev_sync.
