Description Brock Organ 2002-12-02 12:27:33 EST
* for 7.2-s390 product
* customer reported
* request for enhancement: kernel that supports NFSv3

from customer email:

"We are doing some new testing with hipersockets that requires the
performance of NFS version 3. This apparently does not work on the 2.4.9-37
kernel.  Is there a way to get NFS v3 going on this kernel version?"

additionally from the customer:

We are tying to mount MVS datasets and HFS files with NFS version3. The NFS
server is z/OS 1.2 and the client is RedHat 7.2 Kernel 2.4.9-37
running under z/VM. When the mount is invoked under Linux, we receive the
following error:


# mount -o rsize=8192,wsize=8192,nfsvers=3 192.168.0.10:/hfs/u/a056244/redhat72
/home/a056244/redhat72
NFSv3 not supported! 
mount: wrong fs type, bad option, bad superblock on
192.168.0.10:/hfs/u/a056244/redhat72,
or too many mounted file systems 

# dmesg
NFS: NFSv3 not supported.
nfs warning: mount version older than kernel
NFS: mount program didn't pass remote address!

If we use NFS version2, the mount is successful:

# mount -o rsize=8192,wsize=8192,nfsvers=2 192.168.0.10:/hfs/u/a056244/redhat72
/home/a056244/redhat72
# mount
/dev/dasda1 on / type ext3 (rw)
none on /proc type proc (rw)
/dev/dasda2 on /apps type ext3 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/dasdb2 on /tmp type ext3 (rw)

Comment 1 Florian La Roche 2003-05-16 11:43:10 EDT
If this is still an issue, please re-submit into featurezilla for PM
discussions. This should not be mainframe-specific, but a general
feature item.
Closing this bugzilla entry.
