Subject: Bug#315339: installation of new lvm2 renders vg unusable
Date: Tue, 28 Jun 2005 19:11:49 -0400
X-Spam-Status: No, score=-2.6 required=5.0 tests=BAYES_00 autolearn=ham 
	version=3.0.4

Package: lvm2
Version: 2.01.12-2
Followup-For: Bug #315339

Installing new lvm2 makes stripped VG unrecognizable.
Downgrading lvm2 back to 2.01.04-5 fixes the problem.

# vgdisplay lvmg
  LV backup: inconsistent LE count 1832 != 3662
  Internal error: LV segments corrupted in backup.
  Volume group "lvmg" doesn't exist    

Attached is the /etc/lvm/backup/lvmg config file for the group.
