[Bug 207223] Re: File write fails on NFS with a GFS backing filesystem

[mporter]

Also note from the log that one can touch a file (which does succeed),
and the echo also succeeds. It's only when using cp or dd that the
Invalid argument error occurs.

** Description changed:

  Binary package hint: linux-image-server
  
  Release: Ubuntu 7.10
  
  Configuration:
  
  In my simple 3 node cluster I'm using the Ubuntu kernel GFS support. I
  have /home as GFS. I also have /home NFS exported.
  
  Expected Results:
  
    I should be able to mount the NFS exported /home from another system
  and read/write files.
  
  Actual Results:
  
    Copying files to the NFS mounted filesystem fails.
  
    This bug appears to be the same as reported at the RedHat bugzilla: 
    https://bugzilla.redhat.com/show_bug.cgi?id=432544
  
  Detailed log:
  
  root at beef:/# mount foo:/home /mnt/tmp
  root at beef:/# cd /mnt/tmp
  root at beef:/mnt/tmp# touch test
  root at beef:/mnt/tmp# echo foo > test2
- root at beef:/mnt/tmp/mporter# cat test2
+ root at beef:/mnt/tmp# cat test2
  foo
- root at beef:/mnt/tmp/mporter# cp /sbin/init test3
+ root at beef:/mnt/tmp# cp /sbin/init test3
  cp: closing `test3': Invalid argument
  
  Notes:
  
  "dd" will also fail with the same Invalid argument error as a cp when
  the "of=bar" is targetted to an GFS-backed NFS filessystem. This, of
  course, works fine on an ext3-backed NFS filesystem as expected.
