Hi,

  This bug is amd64 specific.  It works fine on 32-bit machines.  It has
been discussed on debian-amd64 mailing lists:

(a) http://lists.debian.org/debian-amd64/2005/07/msg00300.html

(b) http://lists.debian.org/debian-amd64/2006/09/msg00338.html

  Briefly the problem is as follows:

  $ cmkdir directory
  Key:
  Again:
  $ ls
  directory
  $ cfssh directory/
  Key:
  Directory is /var/cfs/.13687.31869
  $ ls
  ls: reading directory .: Input/output error
  $ echo "Hello world" > test.txt
  $ cat test.txt
  Hello world
  $ echo *
  *

  So, as you can see it is possible to read the files, however ls or "echo *"
doesn't list the directory contents.  Even "ls ./" and related commands
will not work.

  By trying many things I discovered that it is possible to read the
contents of the directory by performing the following trick:

  $ cmkdir directory
  Key:
  Again:
  $ ls
  directory
  $ cfssh directory/
  Key:
  Directory is /var/cfs/.13687.31869
  $ ls
  ls: reading directory .: Input/output error
  $ mkdirhier a/a
  $ cd a/a/
  $ ls
  $ echo "Hello world" > test.txt
  $ ls
  test.txt
  $ cat test.txt
  Hello world
  $ echo *
  test.txt

  This is indeed very strange.  I can't tell where the error is but my
guess is that somehow cfsd is not communicating properly with the nfs
daemon.  
  
  Please note that as far as I am concerned this is an AMD64 only problem.
I run cfs on i386 and works perfect!

Regards,

Sergio.
