IRIX NFS server and Linux NFS client

IRIX NFS server and Linux NFS client

[Steffen Persvold]

Hi all,

Is there any reason why my Linux NFS client (kernel 2.4.18
nfs-utils-0.3.1-13.7.2.1 from RedHat 7.2) is not able to mount a directory
exported from an IRIX server in NFSv3 (not sure which version of IRIX
yet, if this is important I will find out). NFSv2 works fine, but if I
try to force NFSv3 I get "Connection refused".

I'll appreciate any help.

Regards,

I forgot to mention that NFSv3 works when an IRIX client mounts the same
directory (i.e the directory shows up as "nfs" and not "nfs2" in the mount
table on the IRIX client).

Could it be that IRIX only supports NFSv3 with TCP and not UDP (I didn't
try TCP mounting on the Linux client) ?

Thanks,

Have you applied

  http://www.fys.uio.no/~trondmy/src/2.4.18/linux-2.4.18-seekdir.dif

in order to work around the glibc-2.x readdir bugs?

Cheers,

[Emanuel Quass]

Hi,

I'm running as Client Linux 2.4.4 (kernel patched by SuSE) against 
AIX-Servers(aix-4.3.3) / IRIX-Servers (6.5.9 and 6.5.11) / 
Linux-Servers(2.4.9 and 2.2.17 both with NFS-Patches) and I can connect from 
my Client to any Server with Version 3 (UDP of course).

I'm sorry that I can't give you a hint apart from upgrading nfs-utils to 
0.3.3.

MfG
	Emanuel

Should work fine. My Linux boxes mount IRIX disks using NFSv3.

Make sure you have Trond's seekdir patch applied and try exporting the
IRIX file systems using the -32bitclients flag - although I haven't seen
"Connection refused" errors without using the patch or the export option
...

Note: I believe the nfs-utils version is irrelevant here as nfs-utils is
for NFS servers.

I haven't applied Trond's patches yet, and I have therefore also
experienced the problems which the patch fixes. I'm compiling a new
kernel at the moment, but I doubt this will fix the NFSv3 issue.

Maybe I should do some tcpdumps to figure out what is happening ?

BTW: The IRIX version on the server is 6.4 if this tells you anything, and
the directory was already exported with -32bitclients.

What version of IRIX are you using?

There was a fix put into IRIX in the 6.5.12/13 timeframe that made it
more compatible with Linux.  Make sure you are updated to at least that
release.

Hmm It's IRIX 6.4 and unfortunately the server can''t be upgraded. Is
there a ChangeLog somewhere (for IRIX) which describes the changes you
mention a bit more in detail ? I looked at the SGI homepage, but I didn't
seem to find
it.

Thanks,

AHHH.  IRIX 6.4...yuck.  All bets are off for that one.  IRIX 6.3 and
6.4 were probably the worst releases ever (said in comic guy voice :). 
6.3 was a one-off to support the o2 and 6.4 was a one-off to support the
Origin 2xxx series.  I would *highly* recommend upgrading to 6.5.x.

For one, NFS v3 was not very mature in the 6.4 days.  I would stick to
NFS v2 if you cannot upgrade the OS.  But *please* upgrade the OS :)
