exporting a nfs filesystem

[Donald C Nelson]

I am trying to export an nfs filesystem from 11i to 10.20 with largefile support. It seems like when the 2GB limit is approach on the 10.20 system, it bombs out. Can a client use an exported filesystem for more than two GB's of data.

First use fsadm to convert the actual filesystem to largefiles support.

fsadm -F vxfs -o largefiles /dev/vg02/rlvol2

You may need to umount, I forget.

Then exportfs -av again.

You may need to upgrade NFS on the 10.20 system. It may not have version 3 on it which
I believe added largefile support.

Stephen, thanks for the response. Even though the exported system is 11.11 with largefiles support, do I have to install the NFS v3 on the 10.20 system?

Hi Donald,

IF you need largefile support on the importing system you will indeed need NFS v3.

Run the following on the 10.2 system:

rpcinfo | grep nfs

If you don't see a 3 in the second column at all then the system doesn't support it.

The exporting and importing systems will negotiate an NFS level *unless* the exporting system "forces" a version in it's export statement or command.

So if there's no v3 support on the 10.2 system & the exporting system is not forcing a version then an NFS v2 connection should be negotiated & be the result.

HTH,
Jeff
