no nfs access after upgrade v14 -> v15

[nerg]

After upgrading, I can no longer access my ns2 via nfs from my Raspberry pi.
I checked /etc/exports and everything looks fine.
Can someone confirm that nfs still works or how I can troubleshoot the matter further?

Oh is that the problem i am having? I had also reinstalled Ubuntu and forgot to backup my fstab NAS mount setting and haven't been able to get it working since. I presumed my syntax was incorrect.

In the meantime i mounted with SFTP but i want to reconnect locally with NFS.

Sorry nerg,

I overlooked your post (several posts in the same time)

Maybe there is a bug with the additional exports file. Seems that its contents is no longer included in the main exports file

Could you confirm me that you use only this options to set nfs access?

If yes, temporarily you can try to use the client Ip to do the same thing

After some more testing,there is no bug with the additional exports file :-D

So to find what happens
* Check if the nfs server is really running

Code: Select all

ps axf|grep usr/sbin|grep -E rpc\|port\|nfsd|grep -v grep

and its output must be

Code: Select all

32059 ?        S      0:00  \_ [nfsd]
  902 ?        Ss     0:00 /usr/sbin/portmap
32053 ?        Ss     0:00 /usr/sbin/rpc.mountd
32055 ?        Ss     0:00 /usr/sbin/rpc.statd

and in NFS menu you should see your selected NFS folders in the 'NFS server's export list' area

Thank you Jocko,

I got the following output:
983 ? Ss 0:00 /usr/sbin/portmap
1021 ? Ss 0:00 /usr/sbin/rpc.mountd
1023 ? Ss 0:00 /usr/sbin/rpc.statd

That's one line short. What am I missing?

Hi nerg

I made a mistake with the command. You should have a line with the daemon nsfd like this

19469 ? S 0:00 \_ [nfsd]

so read directly the output of the command

Code: Select all

ps axf

Previously, I pretty had the same issue and I apparently fixed it by removing some pid files (I am not sure because I don't succeed to reproduce the bug)

So stop the NFS server and post the output of

Code: Select all

ls -al /var/run/

[nerg]

So stop the NFS server and post the output of

Code: Select all

ls -al /var/run/

Ok, here's the output:

Code: Select all

lrwxrwxrwx  1 root root 18 2013-11-17 20:53 /var/run -> /rw_fs/tmp/var/run

Oh, and thanks for this wonderful project. Will donate shortly.

Hi nerg

Oups :dry you need to use the real path so do

Code: Select all

ls -al /rw_fs/tmp/var/run

[nerg]

Code: Select all

root@fvdwsl-base:/ # ls -al /rw_fs/tmp/var/run
total 44
drwxrwxrwx  3 nobody nobody 4096 2013-11-19 19:17 .

Hi nerg,

we will try to stop manually nfs server and remove its pid files.

So in putty do

Code: Select all

/usr/bin/killall -9 nfsd
/usr/bin/killall -9 rpc.statd
/usr/bin/killall -9 rpc.mountd
unlink /var/run/rpc.statd.pid (it should no longer exist and so you can get a warning)
unlinck /var/run/sm-notify.pid

and then try to restart the nfs server
