To Configure Large File Support with NFS
To configure large file support on NFS, both the NFS client and NFS
server must support NFS PV3.
Step 1. On the NFS Server, enter commands similar to those following.
a. To create a new file system with large files enabled, enter a command
like:
/usr/sbin/newfs -F hfs -o largefiles /dev/vg02/rlvol
or:
/usr/sbin/newfs -F vxfs -o largefiles /dev/vg02/rlvol1
b. To mount the file system with large files enabled, enter:
mount -o largefiles /dev/vg02/rlvol /mnt
c. To export a file system, which has been enabled for large files, enter:
exportfs -i /mnt
Step 2. On the NFS client, enter:
mount [-o vers=3] remote-hostname :/mnt /mnt
Large File Support and NFS Protocol Compatibility
Old versions of HP-UX run the older version of the NFS protocol. NFS
Protocol Version 3 (PV3) supports large files (greater than 2 GB), but
Protocol Version 2 (PV2) does not support large files on mounted file
systems. Therefore, compatibility issues may arise in regard to large file
support in a mixed environment, where different systems are running
different versions of HP-UX. If you have an environment which mixes
systems running both NFS PV2 and PV3, refer to the following table,
which shows the compatibility issues that may arise.
