The file system size limit under 2.4 is 2TB, this can be changed to 4TB
if your kernel has the LBD (Large Block Device) patches. Really to only
change is using a unsigned int instead of a signed int.

There are rpms for GFS for 2.4.21-15.EL. I have kernel packages for
2.4.21-15.EL that have xfs and lbd patches if you want them.
