problem with NFS-exporting

Post by Karel.DeBruy » Wed, 15 Jun 1994 16:20:14



Hi,

I have a linux-machine and a DECstation. When I export something from my
DECstation to my linux-machine, I have no problems, everything works fine.

If I try to export something from the linux-pc to my DECstation, I can mount
this on the DECstation, I can ask a directory-list, but I cannot read
anything. I allways get the error-message :
NFS server anarchy not responding, still trying.

I think this could be a time-out problem???

Can anyone help me with this ?

Thanks,

I had the same problem mounting from a linux-pc running kernel-version 1.0.9.
I changed to version 1.1.18 and everything worked fine.

The problem is in the DEC's abusive NFS transfer procedures which assume that
everybody can gobble large NFS blocks.  Unfortunately, they are not the only
ones -- HP and SUN do the same thing.  Use the following parameters on your
mount command to solve the problem:

        soft,rsize=1024,wsize=1024

Linux has promised to fix this problem in their kernel in the future but
right now, the kernel is limited to blocks smaller than 4096 bytes.

Its not really DEC's fault. The NFS spec doesn't have any really nice
parameter negotiation facilities to sort this stuff out. Linux 1.1.18+ seem
totally happy as _servers_ of 8K packets, but not yet as clients. The client
side is currently a mystery.

Really? That would be great!!

My problem: I want to use my Linux box as a server for a diskless SLC
(w/ SunOS 4.1.3). During boot time the SLC wants to mount the root
disk with a packet size of 8K. Later I can change the mount
parameters, but there's no way of changing that for that initial
mount. (At least I don't know one for a Sparc. For a Sun3 I've found
a patch instruction in the linux-Xkernel distribution.)

Should this work with a current kernel version? Which version is
recommended -- 1.22? (I'm more interested in a rather stable than an
experimental version.)

I'm currently running 1.0.8 (from Slackware 1.2.0). When I upgrade to
a new kernel, do I have to install more current versions of the net
software as well? (I think that's net-0.32d, that's right?) Actually,
how do I know which version I've installed currently?

Lots of questions -- I desperately hope someone answers...

Thanks in advance!

Hmmmm I know nothing about kernel internals, but with 1.0.x kernel, or
with newer kernels but without rsize=8192,wsize=8192, on our sun's
partition mounted on linux I get 16kb/sec both reading and writing.
With newer kernels and the rsize=8192,wsize=8192 I get still 16kb/sec
writing, but about 130kb/sec reading (yeah, cheap WD card).
I would say in this case the linux machine is _client_ not server, so
at least one half of the nfs mounting works as clinet, too :)
