Package: lvm-common Version: 1.5.20 Severity: critical Justification: causes serious data loss
When run on a system with LVM1 format volume groups, lvcreate caused the volume group in question to become inaccessible after reboot. callisto:~# lvcreate -L 1G -s -n home-snap /dev/sys_vg/home Invalid LV in extent map (PV /dev/hda7, PE 1792, LV 4, LE 0) Couldn't fill logical volume maps.

Volume group "sys_vg" not found Happily, the volumes in sys_vg stayed active for long enough for me to be able to copy data off, but on reboot, there was no sign of the LVM tools being able to read them (no logs of this, as I wasn't able to bring up the system in multi-user mode). I would have thought that the lvm tools should refuse to operate on LVM1 volumes if doing so would corrupt them. Further evidence of this on: http://weblog.pell.portland.or.us/~orc/2008/02/20/000/index.html Almost certainly not a Debian-specific bug, but this IMO, this is a severe enough problem to warrant recording widely. -- System Information: Debian Release: 4.0 APT prefers stable APT policy: (900, 'stable'), (10, 'unstable') Architecture: i386 (i686) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.22-4-686 Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Versions of packages lvm-common depends on: ii libc6 2.3.6.ds1-13etch5 GNU C Library: Shared libraries ii module-init-tools 3.3-pre4-2 tools for managing Linux kernel mo ii modutils 2.4.27.0-6 Linux module utilities Versions of packages lvm-common recommends: ii logrotate 3.7.1-3 Log rotation utility -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
