[ale] weird nfs problem

[Dow Hurst]

In fact, here is an example from my SGI /etc/exports file.  The syntax 
may be a bit different under Linux.


# NFS exported filesystem database (see exports(4) for more information).
#
# Entries in this file consist of lines containing the following fields:
#
# filesystem    [ options ]     [ netgroup ] [ hostname ] ...
#
# Filesystem must be left-justified and may name any directory within a
# local filesystem.  A backslash (\) at the end of a line permits splitting
# long lines into shorter ones.  Netgroup(4) and hostname refer
# to machines or collections of machines to which filesystem is exported.
#
/d2 -rw=Cedric.kennesaw.edu:Erkki.kennesaw.edu:Aslan.kennesaw.edu:\
Per.kennesaw.edu:Methane.kennesaw.edu:Ethane.kennesaw.edu:\
Heptane.kennesaw.edu:Octane.kennesaw.edu:Raven.kennesaw.edu:\
Hughes1.kennesaw.edu:Fluffy.kennesaw.edu:Knife.kennesaw.edu \
        Cedric.kennesaw.edu:Erkki.kennesaw.edu:Aslan.kennesaw.edu\
Per.kennesaw.edu:Methane.kennesaw.edu:Ethane.kennesaw.edu\
Heptane.kennesaw.edu:Octane.kennesaw.edu:Raven.kennesaw.edu\
Hughes1.kennesaw.edu:Fluffy.kennesaw.edu:Knife.kennesaw.edu


You'll probably have to watch the line wrap.  I found that wrapping 
lines with the backslash worked well for me.  The FQDN was important to 
include since my /etc/hosts entries were passed over the network for 
authentication as FQDNs.  The second set of entries is actually the 
-access= keyword in an implicit format.  Other OSes than IRIX may have a 
different syntax.  Bob Toxen passed on to me that even though Sun has 
published the standards for NFS, almost every server and client he has 
dealt with treats the standards in their own special way. :-)

Here is an example /etc/fstab:

/dev/root / xfs rw,raw=/dev/rroot 0 0
#
#NFS Mounts
walker:/d3          /nfs/walker.d3   nfs rw,hard,intr,bg,nosuid 0 0
raven:/d2           /nfs/raven       nfs rw,hard,intr,bg,nosuid 0 0
per:/d2             /nfs/per         nfs rw,hard,intr,bg,nosuid 0 0
hughes1:/d2         /nfs/hughes1     nfs rw,hard,intr,bg,nosuid 0 0
benzene:/d2         /nfs/benzene     nfs rw,hard,intr,bg,nosuid 0 0
aslan:/d2           /nfs/aslan       nfs rw,hard,intr,bg,nosuid,vers=2 0 0
linus:/d2           /nfs/linus       nfs rw,hard,intr,bg,nosuid,vers=2 0 0
marie:/d2           /nfs/marie       nfs rw,hard,intr,bg,nosuid,vers=2 0 0
azide:/d2           /nfs/azide       nfs rw,hard,intr,bg,nosuid,vers=2 0 0
cedric:/usr/people  /nfs/cedric      nfs rw,hard,intr,bg,nosuid,vers=2 0 0

Note how you can comment the file and comment out mounts.
