Ext2 & 3 should be okay. XFS (very sure) and JFS (reasonably sure)
should also be okay...IIRC. NFS and SMB are probably problematic, but I
can't see anyone really wanting to do this. Maybe some of the
clustering file systems (GFS, etc) might have problems??? I'm not sure
where reiserfs falls. I *think* it's not a problem but something
tingles in the back of my brain that there may be problems lurking...
Just for the heck of it, I did some searching. Found these for
starters:
http://www.suse.de/~aj/linux_lfs.html.
http://www.gelato.unsw.edu.au/~peterc/lfs.html
http://ftp.sas.com/standards/large.file/
So, in a nut shell, most modern (2.4.x+) x86 Linux systems should be
able to handle large files.
Enjoy,
