Problem in mount by nfs a SCO EAFS on a linux box?

[miaping]

Hello all

I Have 2 box:
1-A SCO Openserver 5.0.7
2-A Linux (KNOPPIX 5.0.1).
When I connect them with TCP/IP all connection types can be done but mounting one of SCO EAFS filesystems on the linux box fails. The command used was simple:
mount -t nfs 192.168.50.2:/u /mnt/1
192.168.50.2 is IP of SCO box and /u is a sample directory exported.
When the mount command fails it tells:
Can't read superblock.
How can we mount a filesystem from SCO box on a linux with nfs? What was wrong in our case?
Is this problem because of the nature of SCO filesystem(EAFS) (linux don't know it)? But if this is the problem, this matter must not make problem in NFS protocol?
Thus what is problem?

Any comment will be appreciated
Thanks

What is the content of /etc/exports related to /u in the SCO box ?

Hope This Helps, PH.

Hello PHV
The content of exports is:
/u

But this is not the problem. I know the NFS protocol from 15 years ago and was using it on SCO to connecting to legacy DOS 3.3.

The problem is some other thing relating to superblock. But superblock of which ?( I don't know)

Any comment ?

lately i have been experincing some problems with openserver -> linux nfs mounts. 2 things that i found helpful were on the linux client side mount options....

nfsvers=2
and
rsize=1024,wsize=1024

but these are more related to performance than an error.

take a look at "dmesg | tail" on the linux system after you try to mount the nfs filesystem.

on the sco system do a fsck -ofull on the filesystem you are exporting.
