From: wysochanski@sourceware.org To: lvm-devel@redhat.com, lvm2-cvs@sourceware.org Subject: LVM2/lib/metadata metadata-exported.h metadata.c Date: Mon, 28 Jun 2010 20:36:00 -0000 [thread overview] Message-ID: <20100628203657.18117.qmail@sourceware.org> (raw) CVSROOT: /cvs/lvm2 Module name: LVM2 Changes by: wysochanski@sourceware.org 2010-06-28 20:36:56 Modified files: lib/metadata : metadata-exported.h metadata.c Log message: Add vg get/set methods for VG metadata copies. This patch adds the get and partially implemented set function. The 'set' function should probably ignore or un-ignore metadata areas based on new values.
