I normally try following :
showmount -e ( to check )

Change show attributes of exported dir, select dir and hit enter... It
works
Recycling nfs through nfs.clean and rc.nfs etc..
showmount -e

etc...

These directories are exported. I can list them and even mount them.
They are exported as read only -> /export/sds -ro # in /etc/exports

The reboot suggestion sounds like a win$ person talking and as a first
resolve, is bad advice.

Unfortunately i had to reboot one machine.

Likely, some of the NFS server services are not up/hung.

On the client, what do you get for:
/usr/bin/rpcinfo -p server_name

And on the server side:
lssrc -g nfs
should show you if your rpc.mountd, portmap and nfsd is up.

If it is already up, try restarting portmapper and if that fails,
restart all the nfs services, do a refresh -s inetd or check your
inetd.conf configuration.

If you're still stuck you should read the entire "NFS Problem
Determination" chapter from the AIX System Management Guide.

box01 client
box02 server
##########################

i rebooted the server with NFS

from machine that has low uptime - i can use it with no problem

but it seems that it is a problem of nfs client not server

i have a machine that is working as client - 600days up

If i replace box01 box02 with the roles - box02 is a client
- all works ok.

Mounting from another machine (box10 uptime 2days) to box02 works ok.

Portmap was working , everything seems to work. I went through -> (http://www.unet.univie.ac.at/aix/aixbman/commadmn/nfs_problem.htm) but without comming to any conclussions.
