Hi,

I have a 3 nodes working under PVE 2.0 in cluster since 1 month
today, I stop all VM and I upgrade all server nodes ( aptitude update && aptitude full-upgrade )
but now,

-------
Waiting for quorum... Timed-out waiting for cluster
[FAILED]
------

on the 3 nodes, the /etc/pve/cluster.conf is the same :

<?xml version="1.0"?>
<cluster name="ETSF" config_version="11">
<cman keyfile="/var/lib/pve-cluster/corosync.authkey"></cman>
<clusternodes>
<clusternode name="openvz" votes="1" nodeid="3"/>
<clusternode name="abinit6" votes="1" nodeid="1"/>
<clusternode name="abinit5" votes="1" nodeid="4"/>
</clusternodes>
</cluster>

on each nodes , there are "Quorum: X Activity blocked"

pvecm status on node abinit5, for ex :


Version: 6.2.0
Config Version: 11
Cluster Name: ETSF
Cluster Id: 1124
Cluster Member: Yes
Cluster Generation: 220
Membership state: Cluster-Member

or on openvz :

Version: 6.2.0
Config Version: 11
Cluster Name: ETSF
Cluster Id: 1124
Cluster Member: Yes
Cluster Generation: 68
Membership state: Cluster-Member

the "corosync" service runs on all nodes...
there is the same error message as mentioned in thread : #1

I don't know why but "Expected votes" is 4 indeed of 3 under 2 nodes ( openvz, abinit6 )
I remove 1 month ago a node then the cluster had 4 nodes

it's the problem ?

thank for your help

Dear jmb,

yes, I had the same problem and the biggest problem is, you cant remove a node from the cluster manual - we must complete reinstall one server - and in google nothing to find!
