nfs3 - nfs

[lblauen]

What is the differance between these. Where can one find information on nfs3. The reason this came up is when you do a df -k it does not return the values for Iused and Iused on nfs filesystems but it does on nfs3 filesystems. I checked the /etc/filesystems file and all I can find is vfs=nfs no vfs=nfs3. where is that coming from. Please any ideas would help. Thanks

Just my two cents....
In regard to what is used to mount....
It depends on what both systems can do …both client and server
what versions of NFS do they handle?

Aix, I think at Version 4.2.1 introduced NFS3….
But some with other operating systems have different levels of NFS? And cannot be mounted
At Version 3….

NFS V2 has a 32 bit offset, which usually translates to a 2 GB file limit

NFS V3 has a 64 bit offset, I believe.

The AIX NFS server runs both protocols, NFS2 and NFS3. Use the mount option
vers=[2/3] on the client side to specify the NFS version. The smit panel option is
smitty - communication - NFS - add a filesystem for mounting - NFS version for this
filesystem (TAB key for version 2 or 3 or any).

If you are trying to change the version, unmount it and remount using NFS2 from the prompt.
it goes something like this:
&quot;mount -o vers=2 <linuxhostname>:<sharename> <mount point>&quot;

Type &quot;mount&quot; again to see that the mount options and try it again.
