I've tried lots of different methods, including the one you suggest.
The fs seems to create, but when I try to mount it, /var/log/messages
says:
Jul 6 07:28:59 pecan kernel: VFS: Can't find ext3 filesystem on dev dm-0.
What is the dm-0?
Below is the command where I made the fs I mount to get the above error:
[root at pecan db01_vg]# mkfs -j /dev/db01_vg/db01_lv
mke2fs 1.35 (28-Feb-2004)

This filesystem will be automatically checked every 20 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root at pecan db01_vg]# mount /dev/db01_vg/db01_lv /db01
mount: you must specify the filesystem type
[root at pecan db01_vg]# mount -t ext3 /dev/db01_vg/db01_lv /db01
mount: wrong fs type, bad option, bad superblock on /dev/db01_vg/db01_lv,
or too many mounted file systems
