But how do I mount it when booted up on CD when it's burried somewhere in the LVM on hda2?
Boot normally, stop everything that uses it, unmount it.
If it's something you can't unmount (/, /usr, /var and alike), boot into rescue mode from CD. When prompted, let Anaconda find your existing CentOS installation. It will than create all devices and mount all file systems under /mnt/sysimage. Simply unmount what you need to unmount. Note, if you want to unmount root (and only if you want to unmount root) which is /mnt/sysimage, you'll need to unmount all filesystems under it first. As well as some stuff not shown as mounted by df command (not sure about exact list, try unmounting /mnt/sysimage/proc, /mnt/sysimage/sys, /mnt/sysimage/dev).
Right, if you can't unmount there are several options ... we have a rescue mode on CD-1, the DVD, or the Single Server CD ... also we have the live CD.
The OS you boot to needs LVM2 and all the EXT3 tools ... personally I recommend the LiveCD ... that was one of it's main purposes. It is much more full featured than the rescue mode on the other CDs.
What would be nice, if it already isn't in the live cd, would be a command or binary to look for and mount the existing installations like the rescue mode does. If this is already there, then pardon me, as I haven't seen it. A lot of us know how to walk through and do this, but many people do not.
