Extending LVM partition??

I have Installed a new RHEL 4 AS Update 6 on my HP Proliant machine.
I created LVM during the installation phase. Now I want to extend one of the /dev/VolGroup00/tomcat partition from 1 GB to 2 GB.
I ran the command :

lvextend -L2G /dev/volgroup00/tomcat
and it says:

Successfuly extended.

Do I need to run any more command for the same?
Is it Done?

Does "df -h" report that your partition har increased in size? I wouldn't think so, so you have to run "mkfs.ext3" (or somthing like that depending on your file system type). Are you running ext3?

EDIT: As brianmcgee points out, you should run resize2fs, NOT mkfs. My bad (too early in the morning).

You need to enlarge your filesystem to fill out the new available space. Do so with the following command:

# resize2fs /dev/volgroup00/tomcat

Do reisefs extend the partition without a valid file system from the new disk? Is it possible to make filesystem(using mkfs or mk2efs) on a volume group?

How/where the file system created here for the new VG attached to LVM using resize2fs?
