LVM not active, what am I doing wrong?

[stan <stanb@panix.com>]

I'm trying to set up a LVM (version 1) partiton. I managed to fet it
created, and make a filesystem on it. But when I reboot the machine it does
not get mounted, even though it's in /etc/fstab:

Here is what happens when I try to mount it by hand:

root@mythtv2:~ # mount /dev/mythtv2/lvol1  /mntmp
mount: /dev/mythtv2/lvol1 is not a valid block device

And an lvdisolay looks like this:

root@mythtv2:~ # lvdisplay /dev/mythtv2/lvol1 
lvdisplay -- volume group "mythtv2" of logical volume
"/dev/mythtv2/lvol1"is not active
lvdisplay -- try -D, please

So, lvdisplay with the -D option returns:

root@mythtv2:~ # lvdisplay -D /dev/mythtv2/lvol1 
--- Logical volume ---
LV Name                /dev/mythtv2/lvol1
VG Name                mythtv2
LV Write Access        read/write
LV Status              NOT available
LV #                   1
# open                 0
LV Size                170 GB
Current LE             5440
Allocated LE           5440
Allocation             next free
Read ahead sectors     1024
Block device           58:0

What have I done wrong, and how do I corect it?
