The primary problem comes when you FIPS a partition and cause the cluster size to change. FreeBSD assumes a perfect world while FIPS cheats -- it SHOULD rewrite all those sectors back down to the smaller clustersize but that takes a while (I had a program that actually did it right!) esp. on big disks.
