... what's this ????
Debian sarge 3.1 stable 2.6 ...
pardon ! mount version older than kernel ...

what version of mount do you have (mount --version)? maybe it needs upgrading from whatever comes with sarge.

I'm trying to mount a nfs partion !
Offcourse it's all upgraded ... strange !!!!

I had this error too, NFS volumes still mounted. There is something else wrong with your setup. What does it mean "server localhost not responding"? Are you trying to mount a NFS volume over loopback or what?

slackhack · 05-31-2006, 07:25 AM

is the portmap even running? post ps ax for both machines.

gabsik · 05-31-2006, 09:09 AM

this is the /etc/fstab :

Quote:

192.168.1.6:/media/usb0 /nfs-192.168.1.6 nfs rw,user,auto,rsize=8192,wsize=8192 0 0

Portmap is not installed on the client this is the ps on the server:

Quote:

daemon 2290 0.0 0.2 1612 560 ? Ss May29 0:00 /sbin/portmap

When i mount the nfs partition i get this:

Quote:

root@www:~# mount /nfs-192.168.1.6/
mount: 192.168.1.6:/media/usb0 already mounted or /nfs-192.168.1.6 busy
mount: according to mtab, 192.168.1.6:/media/usb0 is already mounted on /nfs-192.168.1.6
root@www:~# ls /nfs-192.168.1.6/
root@www:~#

that's at least part of the problem, then. the portmapper needs to be running on the client, too.

http://nfs.sourceforge.net/nfs-howto/client.html

try again, and make sure the other stuff is started, too -- lockd, statd, etc. then get back to us.

This is afther i have installed portmap on the client:

Quote:

root@www:~# mount /nfs-192.168.1.6
root@www:~# ls /nfs-192.168.1.6/
root@www:~#

It shouldn't be empty !

slackhack · 05-31-2006, 10:10 AM

what are you trying to mount? say the directory is /nfs and you want to mount it on /mnt/remote. it would be:

# mount 192.168.1.6:/nfs /mnt/remote

Emerson · 05-31-2006, 10:14 AM

And don't forget you need to mount the volume you are sharing on server before exporting it.

slackhack · 05-31-2006, 10:17 AM

that's right, and we're also assuming you've made your /etc/exports file, ran exports -ra if necessary, have host.allow and .deny set up, etc.

Still nothing guys it was working fairly well before ... all of a sudden ...

.... Hm !!! It is a usb hard-disk the one mounted on /media/usb0(the exported dir) and it was unplugged that is why the empty directory .I have resolved the mount older than kernel thing ... sorry and thanks !!!
