nfs-problem

Hi,

if i try to mount an nfs-share like:

mount -t nfs 10.10.13.118:/data1 /mnt/nfs -n -o nolock

i get the following error:

nfs warning: mount version older than kernel

if i try to list the dir with ls it works but if i copy a file from /mnt/nfs to my CF-Card /mnt/ide0

i get an other error like:

(it takes a long time then)

nfs: server 10.10.13.118 not responding, still trying

i searched the forum and see a thread that describe the same error but must i have portmap to do this??

My nfs server is a Suse Linux 9.3 professionell Worksation.

/etc/exports

/data1 *(rw,no_auth_nlm,insecure_locks,no_acl,no_root_squash)

hope someone can help

regards

Mike

    Hi all,

    i browse the Source code of the linux distri und i looked on this:

    Usage Notes

    -----------

    - this version of mount/umount was taken from Slackware v8.1 and ported over

    to work with uClinux 2.4.x

    - In the original version of mount/umount, the etc/mtab and etc/fstab files

    were never referenced (by default)

    is this the reason why nfs do not work with suse 9.3 ??

    I tested Suse 8.2 with Kernel 2.4 and it works fine but we want to use Suse9.3 on ouer server.

    Is there any workaround to get them work?

    Must i make a new mount command ?

    regards

    You can try the busybox mount command... to do this you need to include busybox into your filesystem project re-build and re-upload.

    Once you&#39;ve logged in, run

    busybox mount <options>

    That might help but I don&#39;t think it&#39;s the mount program that&#39;s the problem...

    What type of network adapter are you using on your Nios II board?

    Hello Ken,

    i used a Cyclone I developmentboard from Altera and a Cyclone II developmentboard from Altera.

    On the boards the same networkcard smc lan911c111.

    It tells me the error:

    nfs warning: mount version older than kernel http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif

    I tested the mount command from busybox and it works. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

    I use Quartus 5.0Sp1 Nios II 5.0 and uClinux 1.4, Nios developmentboard Cyclone II EPC2S35 from Altera;

    NFS-Server with bordcomm Gigabit network card and Suse 9.3 (it works with all other applications)

    I think its the normal mount command that not work with new nfs-servers.

    Yesterday i logged the traffic on the network to see whats wrong. The Suse server send all the packets but the Nios

    always want a reply from all packets.

    regards

    Mike
