Re: [Linux-cluster] A few GFS newbie questions: journals, etc

Can you be more explicit please ? When another node comes online it should set the expected_votes to be 50 regardless of any manual intervention. Is that not what is happening ?

Here's relevant snippets from my cluster.conf:

<cman expected_votes="10">
</cman>

<clusternode name="xen1.msp.technicality.org" votes="50">
</clusternode>

<clusternode name="xen2.msp.technicality.org" votes="50">
</clusternode>

<clusternode name="xen-vm-1.msp.technicality.org" votes="1">
</clusternode>

I can bring xen1 or xen2 online without any other nodes online, and get quorum. Once both nodes are online, though, cman_tool status says:

Nodes: 2
Expected_votes: 10
Total_votes: 100
Quorum: 51

..so the quorum value is being raised to 51, which is half+1 of Total_votes, not the Expected_votes (which would be what I'd expect, but again, I'm a newbie.) What I'd really like is a way to lock the quorum number down to 10 (at all times), so if any physical node is surviving the cluster will be up. Is there any simple way to do that?
