Lustre discuss - Jul 2006 - Question about patchless client installation

Hello,
   
  I am trying to install Lustre 1.5.91 with patchless client support, however I
couldn''t find a manual for installation.
   
  I first tried installing only lustre and lustre-module rpms, sounds like this
won''t work, right? Then I switched to using lustre.1.5.91.tar.gz and
running command: ./configure --with-linux=/usr/src/linux-2.6 --disable-server
--disable-liblustre; make;make install.
   
  All steps can be successfully completed, (There are some errors in config.log)
  After that, I run command: mount -t lustre ... to activate clients, however,
it failed and generated the error message to let me check whether lustre has
been loaded or not.
   
  I checked /proc/filessytems and didn'';t see lustre module, then I run
: modprobe lustre. Another error appears: error inserting lustre module...,
unkown sysbmol..
   
  Does anyone have some idea about this or what is the right way to install
client?
  Thanks.
   
  Eric

What is the unknown symbol?  It will be on the console or in dmesg.
What does the output of:

# dmesg

say?

This should be checked by configure, and is #defined to be
grab_cache_page_nowait() if it doesn''t exist...

This bit me too. It seems that the configure-test assumes the 
kernel-source present, but that''s not the case for patchless. I did:

--------------8<-------------

  echo "$as_me:$LINENO: checking if kernel defines

  if test "$HAVE_GCPN_GFP" != 0 ; then

  cat >>confdefs.h <<\_ACEOF

Note that if mm/filemap.c doesn''t exist the output won''t be 0
and
you''ll have a false match.
