Try to downgrade kernel to 2.6.32. According to spirit's post kernel 3.10 has a disabled multicast_querier. And sorry for me, I've forgot to mention that I use 2.6.32 kernel with 3.3 pve. Maybe that's why I don't have such issue after upgrade.

Because with 3.3 you updated corosync too. I would suggest you to use tcpdump. Try to capture multicast packets (see address from pvecm status) when node is failed. Also try to use omping when node is failed to see if it stops to receive heartbeat. And as a final workaround for 3 nodes cluster...

I would suggest you to use tcpdump to debug your problem. Try to capture multicast address (from pvecm status) and see if it stops to comming/sending.

More than 1 day passed since update :) Everything is still fine. So I guess you' problem lies in igmp snooping on vmbr.

Hello! Just add "migration_unsecure: 1" (without quotes) into /etc/pve/datacenter.cfg and migration speed will increase dramatically :)

So, guys! I've also decided to update 3 nodes from 3.2 to 3.3 and updating went fine. I've been already monitoring these 3 nodes about 1 hour and it seems everything OK. BUT I don't use vmbr for heartbeating, I use physical interfaces.

Hello,sirtech! Does your heartbeat between nodes work through vmbr or it uses physical interface? Did you try to use ethX/bondX for heartbeat? This may be important 'cause vmbr is bridge and it acts as software switch for tap-devices connected to it and it has its own igmp snooping settings like...

Hello! Did you try to disable igmp snooping on cisco switch? conf t no ip igmp snooping

Thanks, dietmar! Is it safe to just remove qdiskd from cluster.conf?

Clear! Thanks a lot, Tom.

Hello! I've found this interesting article: http://magazine.redhat.com/2007/12/19/enhancing-cluster-quorum-with-qdisk/ According to it, I can enhance cluster quorum with qdisk. How do you think is it good idea to use qdisk with non-two_nodes cluster and assign more than 1 vote for qdisk (as...

If it's annoying so just use NoVNC-console or SPICE :)

Hello! I would like to suggest you adding ability to start HA VM on specific host by selecting it through the PVE.form.NodeSelector (as it's done in Migrate window). I mean, when you click "Start" button then window with PVE.form.NodeSelector appears and after clusvcadm -e VMID -m $target...

Hello! I have cluster with 3 nodes and 1 qdisk (1 vote for each nodes and 2 votes for qdisk) and qdisk uses /dev/sdb1. But now I want to set qdisk into small LVM partition. Is it enough to just remove it from cluster.conf and add it again or it maybe dangerous? __ Thanks
