Except for being needlessly complicated with the simlink it doesn't
seem wrong. Only if /dev/sdb3 for any reason fails to mount, the
mythtv home directory will be a dead link. So if you feel like
straitening things out I would start by letting all volume groups
point directly to the directories in /media/storage/mythtv ( as I
assume it is called) and not to /var/lib/mythtv, this including the
metadata directories (banners, coverart, fanart, screenshots,
trailers) and video and livetv. Secondly to move everything except the
storagegroups, the metadata directories and video and livetv back
to being strait on /var/lib/mythtv. This last is a bit tricky for you
have to remove the simlink to the directory, which is not easy.

Alternatively to this last part you can change the mythtv
homedirectory to /media/storage/mythtv instead of to the simlink.

sudo usermod -d /media/storage/mythtv mythtv
(assuming the directoryname and the username to be as in the command)

You then can leave the simlink as backup for wherever it might be
hardcoded in any configfile.
Be also sure to set the keep free parameter for the recording high
enough so your home directory can not get into trouble. I suggest 10
Gb

If you want to move the main home directory back to being strait on
/var/lib/mythtv. You do the following:
Make sure mythbackend is not running
log in as a different user then mythtv
unmount /media/storage:
    sudo umount /media/storage
now you can delete the simlink /var/lib/mythtv for it is dead:
    sudo rm /var/lib/mythtv
create the directory /var/lib/mythtv and set the rights OK:
    sudo mkdir /var/lib/mythtv
    sudo chown mythtv /var/lib/mythtv
    sudo chmod 750 /var/lib/mythtv
remount /media/storage
    sudo mount /media/storage
copy everything from /media/storage/mythtv except for the storage
directories, the metadata directories, video and livetv back to
/var/lib/mythtv. Be sure to catch the hidden directories like .mythtv.
Then as an extra check that everything is still owned by mythtv run:
    sudo chown -R mythtv /var/lib/mythtv

Then on the second drive on /media/storage2 you create a recordings
directory as described earlier and add that to the storage group. You
can also do so for for instance livetv.
