CTDB could be more helpful to those of us getting CTDB working on a new file system

[Richard Sharpe]

Hi folks,

All of a sudden, with a new configuration, we started getting this in
the ctdb log file:

2015/01/08 09:54:25.239333 [recoverd: 5824]: ctdb_recovery_lock:
Failed to get recovery lock on '/var/hf/hfmp/somedir/ctdb_reclock'
2015/01/08 09:54:25.239357 [recoverd: 5824]: Unable to get recovery
lock - retrying recovery

Things were working correctly on another two-node setup.

After testing with ping_pong it turned out that the problem is that
the file system is returning EBADF when a lock is attempted, which is
our problem, but it certainly would have been nice for CTDB to tell us
that.
