What are the limits on a file, filesystem?

There are other limits but these come up most often. Logical Volumes
do not _have_ to contain Journaled File Systems and therefore can be
larger than 2GB even in 3.2.5.

File jfs-Filesystem
3.2.5 2GB 2GB
4.1.x 2GB 64GB
4.2 64GB 128GB

While it *might* be possible to create larger file systems, the limits
shown here represent values that IBM has supposedly tested.
