I'm probably missing something very simple. My hard drive looks like this: [root@mavis ~]# fdisk -l
Disk /dev/hdb: 163.9 GB, 163928604672 bytes 255 heads, 63 sectors/track, 19929 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System /dev/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 19929 159975270 8e Linux LVM
Inside the Logical Volume there are my / partition and swap partition and CentOS4 sorts it out just fine.
[root@mavis ~]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) <snip> /dev/hdb1 on /boot type ext3 (rw)
However, if I boot e.g. KNOPPIX, I'm unable to mount anything except the /boot partition on hdb1. Is there any way out of this intolerable situation other than doing a full backup, repartitioning the hard drive without that damnable LVM and restoring the whole thing from the backup?

You could get a rescue CD which understands LVM. Say the FC4 rescue.

Well, I *could* simply boot one of the three CentOS kernels in GRUB's repertoire just as I do on those rare occasions I boot. I was hoping someone could point me to a utility that will undo the LVM mess permanently. I think I've figured out a way to accomodate my current need to have my data available when booted into KNOPPIX but I won't be able to try until tomorrow.

The fact that Konppix doesn't include userland LVM utilities is shortcomming of Knoppix. It does not mean that LVM is a mess. Actually I was extremely dissapointed when I found that Knoppix does not have LVM utilities, not even in DVD version (8GB of all kinds of stupidities you can imagine, but no space for 2MB LVM package).
Maybe you should send email to Klaus and ask him to finally start including the darn utilities as part of the base system, at least on DVD.
Said that, the kernel that comes with Knoppix has LVM support enabled. All you need are userland utilities. You can install them over network using dpkg (or whatever package maintance utilitiy is called in Debian) once you are booted into Knoppix. There are instructions for doing that somewhere someplace (probably typing "knoppix lvm" in Google would find them). If you have USB key, or something similar, you can place the userland LVM utilities on it, so you don't have to install them each time you boot into Knoppix (or maybe you could rebuild your own version of Koppix CD which will have them).

Thanks for your comments and suggestions. I will search for the utilities and put them on a USB key about 1 cup of coffee from now. Like you, if the package is only a few MB, I find it strange that it wasn't included in the 3.2GB DVD iso. I'm sure LVM is great stuff when you have a need for it but when I discovered last night that I couldn't mount my CentOS partition, it brought back memories of Max-Blast and its cousins.
