NFS fsinfo failed for server

[a1a04824]

Hi. I am fairly new to AIX but am an experienced HP-UX and Solaris person.

I am trying to NFS mount a shared directory from a Solaris 8 system to an AIX 4.3.3.0 system. I have verified that the Solaris 8 share is working as it is mountable by other Solaris and HP-UX systems. The problem is, when I try to mount the share on an AIX system, I get an error. The error is below:

You can see I started the nfs subsystem

# startsrc -g nfs
0513-059 The biod Subsystem has been started. Subsystem PID is 9556.
0513-059 The nfsd Subsystem has been started. Subsystem PID is 9036.
0513-059 The rpc.statd Subsystem has been started. Subsystem PID is 10322.
0513-059 The rpc.lockd Subsystem has been started. Subsystem PID is 16650.
0513-059 The rpc.mountd Subsystem has been started. Subsystem PID is 14156.

I can see that the share is available to everyone

# showmount -e 128.66.76.250
export list for 128.66.76.250:
/export/aix (everyone)

And here is the error:

# mount 128.66.76.250:/export/aix /mnt
NFS fsinfo failed for server 128.66.76.250: error 7 (RPC: Authentication error)
mount: 1831-008 giving up on:
128.66.76.250:/export/aix
vmount: There is an input or output error.

Can anyone help me out here? This seems like a simple issue that I am just not getting.

Thank you,
Mark.

You could try adding:
`nfso -o nfs_use_reserved_ports=1`
to the end of /etc/tc.tcpip to force it to use reserved ports again. Also, set the secure mount option to no, and set the transport protocol to use to any.

Or try this workaround:
mount -o vers=2 -o proto=udp IPaddress:/test /mnt

There is also an APAR (IY30001) available for 4.3 that is for this problem but I think is for lpp_source and spots.

AIXSPadmin, I tried what you specified but that did not work (I did not have a /etc/tc.tcpip file). So I had to run the nfso command seperately and that seemed to work!

# nfso -o nfs_use_reserved_ports=1
# mount 128.66.76.250:/export/aix /mnt
# df -k /mnt
Filesystem 1024-blocks Free %Used Iused %Iused Mounted on
128.66.76.250:/export/aix 35009160 11912288 66% 129359 3% /mnt

How do I specify that NFS should always use reserved ports?

Thank you for your help!

Mark.

That should have read /etc/rc.tcpip, and 'r' not a 't' - I mistyped.

You could create a file /etc/rc.tcpip and add the command in it and place /etc/rc.tcpip in you /etc/inittab which is read at boot time. That would be best or use any rc.* file that is read in the inittab and add it to the end of the file.
