[Linux-cluster] lost quorum, but the cluster services and GFS are still up

[Dex Chen]

Hi,
 
I believe that I saw something unusual here.
 
I have a 3 node cluster (with GFS) using CMAN. After I shutdown 2 nodes
in short time span, the cluster shows it lost quorum, but I run the
clustat on the third node, and clustat shows the cluster has 3 nodes (2
are offline) and the other services are up. I was able to access/read
the share storage. CMAN_TOOL shows cluster lost quorum and the activity
is blocked. What I expected is that I should not allow accessing the
shared storage and other services at all when the cluster lost the
quorum. Anyone has seen the similar things? What/where should I look
into?
 
Thanks,
 
Dex
