How to extend the size of an LVM volume RHEL5?

[Marcos Trazzini]

In fact, there's no need to stop the volume group, since it's a
"logical volume extension"... so, the command below should take care
of this (umount the file system before):

# lvchange -an /dev/appsdata/apps1

Now run lvextend and then run lvchange again to re-activate the logical volume:

# lvextend -ay /dev/appsdata/apps1

Don't forget to extend the filesystem itself before trying to remount
it! If it's an Ext3 filesystem, the following command should resize
the filesystem automatically according the new volume size:

# resize2fs /dev/appsdada/apps1

And now finally mount the filesystem /dev/appsdata/apps1 and enjoy!
