hi team
we had a problem in mounting a network file system from source server to target server and we are not able to mount the file system and we checked all the configuration files and we execute the command in the source server
lssrc -a | grep nfsd we found that 2 nfsd in that one is active and another is inoperative
Is this cause for our problem ?or any other thing?
I would recommend stopping the nfs daemon and when the service is completely stopped, including the inoperative service I would then start the nfs daemon. See if that resolves your problem.
I do not know AIX, but I doubt that nfsd has anything to do with mounts. Don't you have a mountd? With most versions of unix, it would handle mounts. Try to restart that if you have one.
Your nfs mount from the other server could be hung on the inoperative nfsd process on the server where the nfs directory exists. I am a little confused that if the nfs mount is not working at all why recycling the nfsd daemon would be a problem. Is the nfs directory you are trying to mount working on other servers? If so, then you may have another issue. What error are you getting when you try to mount the nfs directory?
In AIX NFS - like many other daemons - is handled via a "super-daemon" called "System Resource Controller". Many daemons (in SRC teminology "subsystems" and "subservers") are relying on this mechanism.
They have to be registered, then can be listed (lssrc), (re-)started (startsrc, refresh) and stopped (stopsrc) either one by one or - as they are organized in groups - groupwise.
"nfs" is a group of such subsystems and a running nfs should look similar to the following:
First, try restart your NFS system, in this case not by restarting it but by shutting it down and starting it up anew:
If this fails for some processes the notoriously somewhat unstable (desperately wanting to describe it in accurate terms which, alas, would be NC-21) NFS system of AIX has managed to fail for another time. Reboot the machine.
If this is successful start it up again:
Next part of the debugging would be the file /etc/exports. DO NOT rely on SMITty to edit this file, better do it yourself. Consult your AIX manual on how to do it. Basically it should look like:
The directory /usr/sys/inst.images is exported readonly to only machine machine1, the directory /my/dir is exported for all to use in read/write.
After altering this file put its directives into use by issuing
