[lug] Sun Client Redhat AS3 NFS Probs

[Jeffrey A. St. Pierre]

Ladies and Jellymen,

Sanity is a fleeting thing and I am certainly about to lose mine.  
I have encountered a most perplexing error between a Redhat AS3
NFS server and a Sun Solaris 8 Client.  Essentially the sun
accessing the fileserver works, but causes the server to spool
errors like such:

May 13 11:28:49 <server> rpc.rquotad: Can't find filesystem
mountpoint for directory /export/rd01/stack
May 13 11:28:49 <server> rpc.rquotad: No correct mountpoint
specified.
May 13 11:28:50 <server> rpc.rquotad: Can't find filesystem
mountpoint for directory /export/rd01/stack
May 13 11:28:50 <server> rpc.rquotad: No correct mountpoint
specified.
May 13 11:28:51 <server> rpc.rquotad: Can't find filesystem
mountpoint for directory /export/rd01/stack
May 13 11:28:51 <server> rpc.rquotad: No correct mountpoint
specified.


As far as I can tell, mounting the NFS share on another RH Ent3
box does not cause these errors.  which means there is something
about the mount requests from the Sun that causes it to spew this
error.

Here are the settings on the Redhat Server:

/etc/exports=

  /export/rd01 128.138.xxx.0/255.255.255.0(rw,async)
  /export/rd02 128.138.xxx.0/255.255.255.0(rw,async)  

chkconfig --list

  nfs             0:off   1:off   2:off   3:on    4:on    5:on
                  6:off
  nfslock         0:off   1:off   2:off   3:on    4:on    5:on
                  6:off

And the settings on the Solaris 8 client:

/etc/auto_master=

  # Master map for automounter
  #
  +auto_master
  /projects               /etc/auto_proj  -rw,bg,intr,soft
  
/etc/auto_proj=
 
  # Home directory map for automounter
  # RCS: {$Id: auto_proj,v 1.161 2004/05/11 20:10:46 root Exp $}
  #
  +auto_proj
  stack   -rw,rsize=8192,wsize=8192 \
          <server>.Colorado.EDU:/export/rd01/&

uname -a output:
  SunOS <client> 5.8 Generic_108528-27 sun4u sparc SUNW,Ultra-4


Generally the errors mentioned above spool continuously while
jobs that access the mount are running.  However, I have been
able to run 'du -sm *' on all the sub-dirs from the client side
without generating errors.  I have executed 'dd if=/dev/zero
of=/projects/stack/testfile bs=16k count=61384' and seen no ill
results.  sync or async in the /etc/exports doesn't change
anything... I can't seem to find what is actually placing the
call from the Sun client to the rquotad on the RH server.

Any ideas...

I need to transfer huge ammounts of data to this new RH Server,
so I'd like to solve this problem before I end up with 50GB
messages files.  I'll buy the person who gets me out of this mess
a Mtn Sun beer (or root beer)! Who can say no to that?
