NFS Mount problem


When i am trying to mount a NFS Volume from my workstation i get this error message:
"mount: RPC: Timed out".
But the funny thing is that if i restart the nfs-kernel-deamon on the server i get able to mount one nfs-share, but only one.
So if i restart the nfs-kernel-deamon another time i can mount yet another volume!
How can i mount all the shares at one time without restarting the daemon?. Any suggestions on how i can fix this?

How many are you starting at boot time? The old rule of thumb is to start nfsd daemons at boot time or when you start up NFS on the server side.

hi mate

what does your /etc/exports look like? I hope it has got all the IP addresses/mount etc correctly.

Second thing to look for is tcpwrappers. hosts.allow should have entries for all the daemons if you're denying it from hosts.deny.

Third is IP tables should be off on both server and client (if it is not set to accept all). This is because portmap randomly assigns the port. If you need firewall then there are ways to make daemons bind to one port. See how to to firewall and nfs.

Fourth is nfslock and portmap should be running on the client too.


i doubt 2,3,4 are your problem since you can mount one share or have i read it wrong?

Hi.

Here you got the exportfs file:

frank@picasso:~$ cat /etc/exports
/home/frank/nfs-volume/ 192.168.0.2(rw)
/mnt/hdg/ 192.168.0.2(rw)
/mnt/hde/ 192.168.0.2(rw)
-------------------------------------------------------------
hosts.allow:

portmap: 192.168.0.2
lockd: 192.168.0.2
rquotad: 192.168.0.2
mountd: 192.168.0.2
statd: 192.168.0.2
----------------------------------------
hosts.deny:

portmap: ALL
lockd: ALL
mountd: ALL
rquotad: ALL
statd: ALL
-----------------------

I dont have any firewall up on the server or client.
nfslock and portmap is up on the client and server.
---------------------------------------------------------------------------
Here you got an output from "showmount -a":

frank@picasso:~$ /sbin/showmount -a
All mount points on picasso:
192.168.0.2:/home/frank/nfs-volume
192.168.0.2:/home/frank/samba-share
192.168.0.2:/mnt/hde
192.168.0.2:/mnt/hdg
.......................................................................................
As you can se the line "192.168.0.2:/home/frank/samba-share" is there wich is not in the exports file.

Hello !

I want to restart this thread because i hve the same problems...

I use NFS to serve 3 directorys...

on the client side I mount these Directorys in etc/fstab (in order to get them started during boot time)

but i also get an time out on the second and third NFS-mounts...
only my first directory is mounted after booting....

when i try to mount manually (as root i do: mount /mnt/data2) it work´s!!!
but it´l need a lot of time (min 10sec...)

so i can imagine that there is a timeout during boot....

but why happens this?
and what can we do???

should i write a script which will be automatically started after booting to boot my nfs directorys ???


I have no clue........ :-(


Thanks for Ideas!!!

Liu
