Mounting an old LVM disk

DHCP server died at work today. We mounted the old hard disk on KNOPPIX and thought it would be easy to get the files off the bad hard disk. Well wouldn’t you know, the old dying hard disk is running LVM. Here are the commands needed to mount an old LVM disk.

vgscan
vgchange -a y
mount -t ext3 /dev/my_volume_group/foo /mnt/backup

I searched Google for a solution but every other post on the subject suggested downgrading rrdtool. This is not an appropriate fix. I debugged the actual amavis-stats script and here is my fix. It involves commenting out some lines in /usr/share/amavis-stats/amavis-stats.php:

Line 650:

// $opts[] = "COMMENT:amavis-stats v$asVersion ";
// $opts[] = "COMMENT:$enddate \\r";

Line 771:

// $opts[] = "COMMENT:amavis-stats v$asVersion ";
// $opts[] = "COMMENT:$enddate" . str_replace(":", "\:", $enddate) . " \\r";
