[lvm-devel] LVM2 ./WHATS_NEW lib/activate/dev_manager.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	jbrassow sourceware org	2012-01-23 20:56:43

Modified files:
	.              : WHATS_NEW 
	lib/activate   : dev_manager.c 

Log message:
	Fix the way RAID meta LVs are added to the dependency tree.
	
	Similar to the "mirror" segment type's log device, _add_dev_to_dtree should
	be called and not _add_lv_to_dtree when adding metadata sub-LVs to the deptree.
	Since _add_lv_to_dtree was being called, 'origin_only' could be set if a
	snapshot sits on top of the RAID device.  This would cause the actual device
	that needed to be added to be skipped in favor of the non-existant device,
	"<foo>-real".

 Version 2.02.89 - 
 ==================================
+  Fix the way RAID meta LVs are added to the dependency tree.
   Change exclusive LV activation logic to try local node before remote nodes.
   Add CLVMD_FLAG_REMOTE to skip processing on local node.
   Prompt if request is made to remove a snapshot whose "Merge failed".
