How to determine the max file size

Does anyone know a way to determine the maximum filesize on a file system on Solaris, HP-UX, AIX, Linux, and OSF1 using the command line?

TIA

fsadm <device name>

HPUX fsadm indicates if the file system was mounted to support large files, for example.

I don't know of one single command that can tell you large file support is enabled.
If there are different flavors of filesystems mounted you may see some that do/don't

I think this will help:

mkfs -m <raw_device>

You have to be root to do this (mostly - depends on device permissions).
