[Linux-cluster] DLM locks forever

[Michael Schwartzkopff]

Hi,

I am trying to create a cluster the Red Hat style. I am using cman t ostart 
services like fenced, dlm_controld, gfs_controld and corosync.

At the moment I do not have fencing implemented. I start the fenced with the 
option "-c" because we start the cluster only manually. Basically we want to 
use a GFS2 file system.

Everything works fine up to this point.

But in a split-brain situation both nodes wait for the fencing forever. This 
would be OK. The admin could poweroff one machine. But how can I release the 
lock on the other machine because it is still waiting for the success of the 
fencing. 

Is there any command that tells the fenced on the surviving machine that 
fencing was done manually and it can continue with its operation?

Thanks for hints.
