* 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
# mount -o rsize=8192,wsize=8192,nfsvers=3 192.168.0.10:/hfs/u/a056244/redhat72
NFSv3 not supported!
mount: wrong fs type, bad option, bad superblock on
or too many mounted file systems
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
/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)
192.168.0.10:/hfs/u/a056244/redhat72 on /home/a056244/redhat72 type nfs
If this is still an issue, please re-submit into featurezilla for PM
discussions. This should not be mainframe-specific, but a general
