nfs client problem

Hi,

When trying to troubleshoot nfs mount problem I found that nfs mount dont care about options.
At first I used this line :

mount -t nfs -o tcp,nfsv3,hard,intr ccdtli94.in2p3.fr:/sps/bioaster /gpfs

and got :

[tcp] ccdtli94.in2p3.fr:/sps/bioaster: RPCPROG_NFS: RPC: Port mapper failure - RPC: Timed out

BUT when I tried this :

mount -t nfs -o tcp,nfsv3,hard,intr,smurf,error ccdtli94.in2p3.fr:/sps/bioaster /gpfs

or even this

mount_nfs -o blob ccdtli94.in2p3.fr:/sps/bioaster /gpfs

it's exactly the same timeout error but no error spoted in the command line.
Someone can explain or it's a bug ?
 
If I reply to myself, does it count for someone helped ? ;)
Seriously, it's seems that this is not a bug but a feature (dooooh !!). Not understood options are just ignored in order to improve inter-operability.
 
Works for me. It reports wrong options like it's supposed to. It probably doesn't check your options because there is an earlier error (the timeout).
 
Now on the pbm itself (assuming options are ok).

sudo mount -t nfs -o nosuid,nodev,vers=3,hard,intr,port=664 ccdtli94.in2p3.fr:/sps/bioaster /gpfs
[tcp] ccdtli94.in2p3.fr:/sps/bioaster: NFSPROC_NULL: RPC: Program unavailable

While this similar command is ok on a linux box (mount is ok and files are there) :

sudo mount -t nfs -o nosuid,nodev,tcp,nfsvers=3,hard,intr,mountport=664 ccdtli94:/sps/bioaster /gpfs
