Tell automount to use NFSv2 on AIX 6.1
Hello,

I have a CentOS 6.1 server exporting a filesystem with read/write to world. I have an AIX Client mouting this filesystem from an NIS map. One of our applications is giving an error and after a little research, we found that we need the AIX Client to mount this filesystem with NFS V2 for the application to work.

Will you please help me with the below questions?

1- How can I tell which version of NFS is used to mount a specific mount?
I did google this and the forums suggest using rpcinfo -p but the results are not very clear. My output below.


Code:
bash-4.2#  rpcinfo -p
   program vers proto   port  service
    100000    4   udp    111  portmapper

    100005    3   udp  58635  mountd
    400005    1   udp  58636

I want to know NFS version used to mount /u/mego/INTERSITE.


2- How can I explictly use NFSv2 to mount on the AIX Client?
