[fuse-devel] NFS and direct_io

[David S. <ds...@ja...>]

In testing, I've found what seems to be a problem with NFS and the
direct_io option.  Basically, without direct_io, a regular fuse mount
works as expected over NFS.  When flipping direct_io on, the sequence
of events for a cp onto an already-existing file is:

  GETATTR /file
  TRUNCATE /file to 0
  OPEN /file with flags 100001

then nothing.  The cp just blocks at that point and the filesystem
program gets no further calls.

This is latest CVS fuse and kernel 2.6.10.
