rbd docker plugin lock/unlock

[WhtAlpha]

I have two machines e.g. A and B. A is running rbd docker plugin and mounting, when the failover happens, A down , B up, B cann't use docker to mount because of the A's lock is not released , how to solve HA or Failover ？

Hi @WhtAlpha. How do you take A down and how do you bring B up?

@porcupie, did you fix symptoms like this in your fork?

Hi @hekaldama If the machine A failure, the machine A shut down, to replace the machine A work is the B machine, then due to the RBD before the A machine docker plugin did not have time to unlock, resulting in B on the machine running the docker unable to mount on,so I have no idea how to solve the question when the HA or Failover is happening.
