Hi,

I changed the value of RPCNFSDCOUNT in /etc/default/nfs-kernel-server
(ubuntu). Do I need to restart the machine?

Or I need to restart nfsd? If so, would you please let me know how to
restart nfsd?

Peng

Easiest thing to do is simply

   rpc.nfsd $NUMBER

it will change the number of running threads to match the number that you
give.

You still need to stop and restart the nfs for this to take effect.

Have you tried it?

I assure you that running rpc.nfsd like this does change the number of
threads from whatever it is to the given number. (I should know, I wrote the
code :-)

No it does not if you check how many daemons are running (ps) you will see  
that it only
changed the value not the number of running daemons.

So when I run "rpc.nfsd N" and I check with "ps" how many deamons are
running, I find that N are running.

Maybe you mean something different??

This will change the number in /etc/default/nfs-kernel-server? Or it
will not, meaning if I reboot machine, there will still be an old
number of nfsd running?

Try it an see ???


No, it doesn't change any file.  It just changes the number of running
threads.

If you want to change the number of threads at next reboot, change the file.
If you want to change the number of threads running now, run the command.
If you want to do both, do both.
