[ELDK] Mount NFS problem

[Detlev Zundel]

Hi Zaahir,

> Problem is unable to get the NFS mount

One thing I really would try is to use a different PC instead of the
sequoia to make sure the server side is ok.

> (Sequoia board)  Server IP  192.168.1.101
> (PC)                  Client  IP   192.168.1.10

You switch terminology here - I presume the PC is the NFS server and
sequoia is the client "mounting" the file system.  Wow, this is
confusing - is it correct that your server, i.e. the PC has the IP
192.168.1.101?  Please only list the IPs of the boards, not any IPs of
"network targets"...

Well now I'm having a problem, because I don't know if the PC is the
server also in your terminology - but if it is and if your chart above
is right, then this exports the NFS only to the server itself.  You
should change it to either 192.168.1.0/255.255.255.0 for the whole
subnet or at least to the correct IP of sequoia.

If you do mounts manually, you don't need an fstab entry at all.  This
is only used for "mount -a".

Well this sounds pretty obvious - Somehow the export entry does not
allow the sequoia board to mount the directory.  As mentioned try this
in /etc/exports on your PC and then work out the difference (maybe the
missing netmask is a real bummer?!?):

/opt/eldk	192.168.1.0/255.255.255.0(rw,no_root_squash,sync)
