Fail to start rpc nfsd

Fail to start rpc nfsd

[Stephen Liu]

Hi folks,

Ubuntu-6.06.1-LAMP-server-amd64

I'm following;
https://help.ubuntu.com/ubuntu/serverguide/C/index.html
Network File System (NFS)
https://help.ubuntu.com/ubuntu/serverguide/C/network-file-system.html

to build a LAMP server which is for test only, not for production.
Failed to start "nfs-kernel-server"


$ sudo /etc/init.d/nfs-kernel-server start
Password:
 * Exporting directories for NFS kernel daemon...
[ ok ]
 * Starting rpc nfsd...                              [fail]

$ sudo /etc/init.d/portmap start
Password:

 * Not starting portmap daemon.  Already running.     [ ok ]
* end *

It said already running.

What will be this command for;
/etc/init.d/nfs-kernel-server start


Each time after running "apt-get upgrade" or installing a new package,
it will automatically run the said command at the end.  It hung there
for a while before [fail] popup.  How to fix it.  TIA.

Depending on the distribution, it may just be that the script left a
lockfile or something out there. Make sure it's actually running with
'ps'.

If that's not it, then it's just not responding for some reason. Check
your firewalling and make sure you're not blocking port 111. If that's
not it, then it's probably hung for some reason and you'll need to do a
bit of investigation as to why.

Which lockfile?  Tks.

$ ps -ef | egrep '/nfs-kernel-server'
satimis   4841  4786  0 08:16 pts/2    00:00:00 grep -E
/nfs-kernel-server

It is not running.

It's portmap you need to grep for.

Hi J. Bruce,

Tks for your advice.

$ ps -ef | egrep portmap
daemon    3513     1  0 07:58 ?        00:00:00 /sbin/portmap -i
127.0.0.1
satimis   4902  4786  0 09:01 pts/2    00:00:00 grep -E portmap
* end *

It is there.


Why each time on running;
$ sudo /etc/init.d/nfs-kernel-server restart
Password:
 * Stopping rpc mountd...                                              
                 [ ok ]
 * Stopping rpc nfsd...                                                
                 [ ok ]
 * Unexporting directories for NFS kernel daemon...                    
                 [ ok ]
 * Exporting directories for NFS kernel daemon...                      
                 [ ok ]
 * Starting rpc nfsd...                                                
                 [fail]
* end *

It hung on "Starting rpc nfsd..." a while before [fail] popup.  And
each time after "running apt-get upgrade" or after installing new
package it repeats running the above commands.  Finally failed.

Is there anyway to fix the said problem?  TIA

Check that you don't have an entry in /etc/hosts.deny that is blocking
access to portmap. Also check that you don't have any iptables entries
that are doing the same.

Nothing enabled on /etc/hosts.deny file.  Just retain its original file
without touched.
