Description Milan Broz 2008-10-17 13:59:52 UTC

The _vg_write_raw function has a bug in calculating offset in metadata buffer which can corrupt (in rare situations) volume group metadata.

For more info see original report:
https://www.redhat.com/archives/lvm-devel/2008-October/msg00012.html

Patch to fix this issue is already upstream.
