nfs 4 / nfs3 back porting problems..


Hi all,
after RHEL 6 has someone out, ext4 FS that is exported as NFS, and some OS with NFS3 or older mounting it, we know there are issues.. do we have some stable solution to that yet..
does RHEL 6.2 address any problems relevant to this back-porting problem.

I'm currently running Fedora versions 4 through 16 on various machines, ext3 and ext4, NFS v3 and v4, all machines remote mounted on all others, and have no issues to speak of.

What issues are you having?

Here's what I remember being the problem: If we had some home dir's on RHEL 6.2 / EXT4 / NFS server and were mounting on to a RHEL 3 or older OSes, we had to force / modify the nfsmount.conf to indicate
[ Server 'servername' ]
nfsvers=3.

now I dont exactly remember if the hosting OS was at RHEL6.2 and mounting OS was Pre RHEL3 or the flip side, but we had to explicitly indicate a nfs version number to communicate without problems. Do you have a similar scenario?

I will sometime soon, setup a new hosting area with RHEL6.2 or better, but i am afraid, if it people can safely amd/auto mount their homes from RHEL6/5/4/3.. does any have any past exposure here??

I have similar mounts, but I don't have to specify the nfs version to use. Procedure was just like any other machine for me. Set up the clients' hostnames in /etc/hosts on the server, set up the clients you want to be able to export to in /etc/hosts.allow under portmap, lockd, rquotad, mountd, and statd, set up /etc/exports on the server like so: "/home/user 192.168.1.0/24(rw,sync)", restart exportfs, and then mount it on the clients like: "server:/home/user /home/user.server nfs rw 0 0". It works the same in reverse (mounting an NFS v3 server on an NFS v4 client) as well.
