> Attached are a bunch of patches that clean up the CTDB recovery lock

> The most obvious changes are:
> * ctdbd aborts with a clear error message if it can take the recovery
>   lock during recovery, when it should be held by the recovery daemon
>   on the recovery master node.  This removes any ambiguity about
>   running with a broken recovery lock.
> * VerifyRecoveryLock tunable is obsoleted.  If you don't want a
>   recovery lock then don't set one.
> * Code cleanups.
> * Documentation improvements.

Re-pushed to my ctdb-recovery-lock branch with a minor change.

This patch:

  ctdb-daemon: Log a warning when setting obsolete tunables

now logs the warning after setting the variable.  This makes a
potential future change (return non-zero when setting obsolete variable)
slightly simpler.  :-)

peace & happiness,
