Regarding testing of NFS over RDMA patch on AMMASO RNIC.

[Sivakumar Subramani]

Hi James,

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<JAMES>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
I suggest you do the following:

1. On the client

 dmesg -c
 echo 32767 > /proc/sys/sunrpc/rpc_debug
 echo 65535 > /proc/sys/sunrpc/nfs_debug

2. On the server

 dmesg -c
 echo 32767 > /proc/sys/sunrpc/rpc_debug
 echo 32767 > /proc/sys/sunrpc/nfsd_debug

3. Attempt a mount.

4. On the client

   dmesg > /tmp/clnt.txt

5. On the server

   dmesg > /tmp/srv.txt

Please send the the two log files and we will try to get to the bottom 
of this.

Now I am able to do normal TCP nfs mount. As per your previous mail, I have collected the log files on server and client systems. The files are attached with this mail.
I could see some error messages in the client log. Please let me know if you find any issues.

[root at tyan ~]# mount -t nfs 10.114.52.99:/home/ssk /mnt
[root at tyan ~]# cd /mnt
[root at tyan mnt]# ls
backup   dev_kma  kernel  load_mod         ogc_amso      server.txt
Desktop  ip.conf  kma     nfsrdma20060804  ogc_amso.tar  tools
[root at tyan mnt]# cd ..
[root at tyan /]# umount /mnt


[root at tyan nfsrdmamount]# ./nfsrdmamount -o rdma=192.168.69.148 192.168.68.148:/tmp /mnt
Doing nfs/rdma mount to 192.168.69.148, mount protocol to 192.168.68.148

Hi Siva,

I don't see any obvious errors in the information you provided. To 
configure your systems, I suggest you follow these instructions:

 http://nfs.sourceforge.net/nfs-howto/

You definitely need NFS TCP/UDP mounts working before attempting to 
setup NFS-RDMA.
