Error description

  • A Linux NFSv4 client may hang when accessing an AIX NFSv4
    server during file access.  The iptrace reveals an
    infinite
    loop during the NFSv4 SETCLIENTID_CONFIRM operation with
    the AIX server returning the NFS4ERR_EXPIRED error.
    
    This has been seen at least on Red Hat Linux V6.3 client.

Problem summary

  • Redhat Linux client might experience a hang upon doing read
    operation on a file from NFSv4 exported directory.
    

Problem conclusion

  • Client record time is renewed when the DELAY error is returned
    to the client. this will make sure NFS4ERR_EXPIRED error not
    returned to client.
    

Temporary fix
