With UFS1, the practical filesystem limit is 1TB, but if you fool with block sizes, you could get much more. UFS2 supports much more than that. And there is nothing to prevent you from creating multiple filesystems. You might want to do that anyhow. > requirements in terms of memory, etc to mount the > partition.

FreeBSD doesn't need to allocate a lot of memory to mount a filesystem. I know that some OSes allocate an amount of memory proportional to the size of the filesystem, but FreeBSD does not do that. > Thanks for any input. > > Eric Tom
