Passing the automounter mount options

Passing the automounter mount options

[Justin Rush]

Hi,
  I am troubleshooting nfs performance and I am trying to pass some 
options to the automounter.  We are using NIS with an auto.home file to 
automount user's homedirectories.  I have a line like :
jrush -rw,soft,rsize=32768,wsize=32768,nfsvers=3 host:/path/to/home
However it does not seem to work because I do not get the same perfermance 
as when I do an nfs mount manually, ie. mount -t nfs host:/path dir/ -o 
rsize=32768,wsize=32768,nfsvers=3

Am I missing something here or just editing the wrong file?

Any input is greatly appreciated.

Does /proc/mounts say that it is actually mounted with those options?

If not, then chances are the NIS map didn't get rebuilt.  Did you re-run 
'make' in /var/yp on the nis server?  If you are using NIS slaves, did 
you push the maps to them?

You didn't specify which OS/Distro, but on my Redhat machines, I edit the
/etc/init.d/autofs init script directly. There is a section in the init
script that allows you to specify mount options and daemon options.

Ie:
#
# We can add local options here
# e.g. localoptions='rsize=8192,wsize=8192'
#
localoptions=''

# Daemon options
# e.g. --timeout 60
#
daemonoptions=''

Thanks to everyone for their input,
  I did try to originally put it in the auto.home file, and yes I did 
remake the NIS files and push them out.
  When that didn't work, I tried editing the autofs init script, however 
this seemed not to work either.
localoptions='rsize=32768,wsize=32768,nfsvers=3'
is the line that I used.
I am running redhat 9 with all the updated rpms.

Is there anything else that I missing?
Again, any responses are greatly appreciated.
