Fresh install of ATS 6.1.2 cannot use disk cache file > 1.6T.

I tried it with several sizes. I can create cache.db with max 1600GB. Anything
bigger results in the cache being disabled (log above). It actually creates the
file with the mentioned size, file permissions are ok but it always complains
that "disk header different for disk /data/trafficserver/cache.db: clearing the
disk" and "failed to initialize the cache for http: cache disabled".
Strange thing is that we use the same version on other servers where we
upgraded an installation from a previous version. cache.db file already existed
and this is working fine.
