I'm testing drbd on a debian sytem. (drbd 8.9.2)
My setup is two nodes with a primary-primary setup with gfs2

I mount the cluster resource in the local filesystem. (/dev/drbd0 on  
/clusterdata type gfs2)

When I kill one node (take the electircal wire) the still existing  
node can't access the files:

ls -l /clusterdata hang up, I can't kill the command, even from a  
other root account with kill -9

Is this a problem with drbd or maybe with gfs2?

How to bring the situation under control?
