[lvm-devel] LVM2/lib/metadata metadata.c



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2009-09-02 21:39:49

Modified files:
	lib/metadata   : metadata.c 

Log message:
	Update vg_remove_single_* functions to use the removed_pvs list.
	
	Now that we've split vg_remove_single into two routines, in the first routine
	that only manipulates memory, we move the PVs from the vg->pvs list to the
	vg->removed_pvs list.  Then later, we iterate through this list to write the
	removed PVs to disk, which removes them from the volume group and places them
	into the internal ORPHAN VG.
