Problems in configuring SNFS

Problems in configuring SNFS

[lizhong]

Hello all,
I'm trying to set up SNFS on my Redhat server. I have read all
infomation in this page:
http://www.math.ualberta.ca/imaging/snfs/
I have set up the SNIS server successfully, but when I failed in setting
up the SNFS server. The host name of my SNFS server is gcnode029, and my
client is gcnode010. I can mount directories from gcnode029 to gcnode010
using common NFS, but failed in mount ing directories using SNFS.

I configured SNFS like this:
1. Run command "snfshost gcnode029:200008" at client gcnode010.
2. Add this into /etc/fstab at client gcnode010:
gcnode029:/home/ha /home/ha nfs
user,noauto,hard,intr,rsize=8192,wsize=8192,mountprog=200008,nfsprog=250008
0 0
3. Run command "rpc_psrv -r -d /usr/local/etc/snfs/gcnode029" at client
gcnode010, then enter gcnode029's root password. Now I saw "ID String
correctly read: RPC Proxy Client".
4. Run command "mount /home/ha", then I got the following error message:
mount: mount to NFS server 'gcnode029' failed: RPC Error: Program not
registered.
5. Run command "ps -aux | grep rpc" at host gcnode029:
root 5278 0.0 0.0 1656 744 ? Ss Mar05 0:00 rpc_pcl -P -1 -e
snfs-genode010-200008.log -d -M 200008:100005

If I simply run command "mount -t nfs gcnode029:/home/ha /home/ha", I
could get the remote directory. But in this way, I just used the common
nfs, not SNFS. It seems that for some reason, rpc_psrv received no
message from mount /home/ha, and nothing was sent to host gcnode029.

Thank you for any help!

Unfortunately nothing in the above explanation can be used
to help debug this problem.

Fortunately, the people at Bull have come up with commands that will 
help set up a Kerberized NFS environment. See:
 
    http://nfsv4.bullopensource.org/doc/kerberosnfs/krbnfscmd_v2.php

I would start there...
