[Ocfs2-users] servers blocked on ocfs2

[frank]

Hi Joel, thanks for your answer,
usually when the cable is unplugged it appears messages related to link, 
and there isn't. I thought in a OpenVZ issue also, but I don't find any 
evidence of that.
There is a dedicated link as a mentioned, used for OCFS2 and 
heartbeat/Pacemaker; may be last one hampered the interface.

Anyway, if there was a cut in the heartbeat or something similar, one of 
the nodes should have fenced itself, haven't it? Why did the nodes  
stall? Can we avoid that?
