    I run a fairly large server for a group of researchers at the
    University of Colorado. I have served most of my NFS Shares from
    a Sun E450 running Solaris 8. Recently we setup a
    Penguincomputing Relion240 running RH AS3. Attached to it is an
    adaptec 29160 SCSI card attached to a Promise RM8000 RAID (1.5
    TB). This RAID is going to store all of our data to be nfs
    shared out, but I have to move stuff piecemeal and I will have a
    few nfs servers until I can centralize all data on the new
    system.

    I just moved the first major project over to the RAID and shared
    it out. The user of the project has to run Sun-compiled code, so
    the data automounts on the Sun and the job runs, slowly, probably
    due to NFS settings that I can tweak, but it runs. The thing
    that worries me is the errors that are filling up my
    /var/log/messages on the Redhat Server:

    May 12 09:04:03 <servername> rpc.rquotad: Can't find filesystem
                    mountpoint for directory /export/rd01/stack
    May 12 09:04:03 <servername> rpc.rquotad: No correct mountpoint
                    specified.
    May 12 09:04:25 <servername> rpc.rquotad: Can't find filesystem
                    mountpoint for directory /export/rd01/stack
    May 12 09:04:25 <servername> rpc.rquotad: No correct mountpoint
                    specified.
    May 12 09:04:47 <servername> rpc.rquotad: Can't find filesystem
                    mountpoint for directory /export/rd01/stack
    May 12 09:04:47 <servername> rpc.rquotad: No correct mountpoint
                    specified.
    May 12 09:23:46 <servername> rpc.rquotad: Can't find filesystem
                    mountpoint for directory /export/rd01/stack
    May 12 09:23:46 <servername> rpc.rquotad: No correct mountpoint
                    specified.

    where <servername> is my Redhat AS Relion server

    As you may have guessed "stack" is the name of the project. It
    automounts under /project/stack as per /etc/auto_master and
    /etc/auto_proj. These errors crop up continuously. When he
    actually runs code on the Sun client these messages spool every
    15 seconds or so on my linux server. Needless to say, by the
    time I transfer 100 or so projects over to the RAID, my messages
    file is going to overflow /var/log.

    These are my settings on the linux server:

       rpms:
       kernel-smp-2.4.21-9.0.3.EL
       kernel-utils-2.4-8.37.1
       nfs-utils-1.0.6-7.EL
       autofs-3.1.7-41

       /etc/exports:
       /export/rd01 aaa.bbb.ccc.0/255.255.255.0(rw,async)
       ## Note: sync tried, results the same.

       where aaa.bbb.ccc.0 is my class C subnet

    and my settings on the Sun client:

       kernel patch level:
       5.8 Generic_108528-27

       /etc/auto_master:
       
       # Master map for automounter
       #
       +auto_master
       #/net -hosts -nosuid
       /autohome /etc/auto_home -rw,bg,intr,soft,actimeo=0
       /homes /etc/auto_users -rw,bg,intr,soft,actimeo=0
       /projects /etc/auto_proj -rw,bg,intr,soft,actimeo=0
       /misc /etc/auto_misc -rw,bg,intr,soft,actimeo=0
       /- /etc/auto_direct

       
       /etc/auto_proj (Abbreviated entry):

       # 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 \
                <servername>.Colorado.EDU:/export/rd01/&

    So... does anyone see possible errors in my setup that would
    cause these bizzare error messages? This is very critical,
    because I have to get things moved to the new server, but I can't
    have a 50GB messages file in 1 day, and also it forbodes worse
    things to come. I'm assuming I just have something setup wrong.

    Thanks,

    Jeff
