The kernel that you are using may not be able to see more than 2TB.
Previously we had a similar problem and solved it by using the XFS
kernel, which is capable of seeing large volumes. I suggest having a
look at the SL5.3 release notes to see if there is mention of kernel
limitations.
Good luck,
Jimmy
