Setting up proxmox cluster in ovh

[Ponury Typ]

Hi guys, i am after long night fighting with this. I have right now 2 servers (another one is on the way) in ovh runing proxmox. I was trying to connect them in cluster but quorum keep failing at connecting (node->master).cluster.cfg/etc/hosts

127.0.0.1 localhost.localdomain localhost37.xxx.xxx.xxx server1.xxx.xxx server1151.xxx.xxx.xxx kebab.xxx.xxx kebab::1 ip6-localhost ip6-loopbackfeo0::0 ip6-localnetff00::0 ip6-mcastprefixff02::1 ip6-allnodesff02::2 ip6-allroutersff02::3 ip6-allhosts

I know that ovh dont support multicast but this settings should allow me to set up cluster anyway. What am i doing wrong ?

For some reason forum dont let me format post so i paste on pastebin cluster.cfg and hosts. http://pastebin.com/6iFVZKHi

I think that ovh Vrack option allow private network && multicast between hosts ?

Ye i am aware of this but this servers are from ovh sos offer so vrack isnt option for them. I think i will have to solve this with vpn.

Are you sure that they support Multicast in their vRack and not rather Unicast?

we use proxmox with clustering on ovh and vrack, so.. i mean it works for sure... just a matter of all your settings... are you able to ping each of the computers on the private vrack ips?

We don't have a vRack yet, but I would be very interested in one if Proxmox clustering and Multicast is working without problems. Does OVH also support internal 10 GBit connections?

some of their servers in the infrastructure, storage, and hg packages are dual 10gigabit nics
as far as multicast support i believe its just unicast (though none of our servers have <cman keyfile="/var/lib/pve-cluster/corosync.authkey" transport="udpu"/> on them and they seem to work just fine)
when testing using omping we get this unicast, seq=1, size=69 bytes, dist=0, time=0.114ms
