Thanks for your answer, Brett and Shafeeq.
The venus crashed after I did a cp in the replicated
volume which has been setlogparms seperately on both
replica, and vutil -shutdown couldn't shut venus down.
Finally, I kill it. I'm using Linux 7.0, Coda 5.3.14.
I just thought that there might be a way to force the
resource being released even when venus has been
abnormally shutted down.
