Martin Schwenke 82e7f38214 ctdb-config: Change example recovery lock setting to one that fails 
ctdbd will start without a recovery lock configured.  It will log a
message saying that this is not optimal.  However, a careless user may
overlook both this message and the importance of setting a recovery
lock.  If the existing example configuration is uncommented then the
directory containing it will be created (by 01.reclock.script) and the
failure (i.e. multiple nodes able to take the lock) will be confusing.

Instead, change the example setting to one that will result in banned
nodes, encouraging users to consciously configure (or deconfigure) the
recovery lock.  Tweak the corresponding comment.

README 

This directory contains run-time support scripts for CTDB.

Selected highlights:

  ctdb.init

    An initscript for starting ctdbd at boot time.

  events/

    Eventscripts.  See events/README for more details.

  functions

    Support functions, sourced by eventscripts and other scripts.

  statd-callout

    rpc.statd high-availability callout to support lock migration on
    failover.

Notes:

* All of these scripts are written in POSIX Bourne shell.  Please
  avoid bash-isms, including the use of "local" variables (which are
  not available in POSIX shell).

* Do not use absolute paths for commands.  Unit tests attempt to
  replace many commands with stubs and can not do this if commands are
  specified with absolute paths.  The functions file controls $PATH so
  absolute paths should not be required.
