mounting partitions in single user mode

I'm trying to do an exercise from Jang's RHCE prep book. On page 178 he has the reader rename the inittab file, reboot, and troubleshoot from single user mode.

When I do this, I'm unable to mount directories. The mount command indicates that /var is mounted. But when I go to the directory, there is nothing in it. It is in a logical volume. When I try to mount it, I get an error message that the device /dev/mapper/VolGroup01-LogVol01 does not exist. And I don't see any volume groups in the /dev directory. Similarly, the /home directory is showing as mounted, but there are no files or directories there.

So . . . what do I need to do in order to mount logical volumes in single user mode?

As I understand it, var is only showing because single user mode mounts root and thus also the full directory tree - but not the actual partitions that should be mounted there. Plus root will usually be mounted read-only unless you explicitly remount it mount -o remount,rw. Thus you get the impression that things are mounted while, in fact, they are not. Manipulating things manually does not always work since single user mode has access to only a limited number of the commands that would usually be available. You could verify by issuing an echo $PATH - I'm sure you'll see that it is a lot shorter than it would otherwise be. Now, it should still be possible to mount logical volumes but you need to specify the file system type as in:
mount -t ext3 /dev/mapper/VolGroup00-LogVol02 /foo
