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, Greg
