[CentOS] Mount Point Ownership & Group

I am facing problems assigning the owner and group to an ext3 filesystem being mounted from an external storage. I created a mount point /vol and changed its owner and group to alpha and beta respectively (as required). The ext3 filesystem (LV from the external storage) was then mounted on /vol using the mount command. However, after mounting the filesystem the owner and group of /vol changed back to root.

How do I ensure that the owner and group for this (and other) external filesystem to be mounted dynamically are preserved as required ? The mount options uid and gid don't seem to work for ext3 filesystems. Are there any other options for this purpose?

Thanks,

Manish
