How will Proxmox 2.0 HA work?

[Ninjix]

Is there any documentation anywhere that describes how the Proxmox team is implementing HA in version 2.0? I'm also interested in the features the HA will support.

Some questions I have:

• How will heartbeats between hosts and KVMs be handled?
• Will there be a feature for automatic "fencing" of host nodes?
• What assumptions and rules will nodes use when they loose contact with a master?
• How many master servers will be supported?
• How will the cluster determine which node to re-lauch downed KVM?

Thanks

I don't know if you mean HA or FT, but look into the kemari project (they are trying to integrate with kvm).

We will use corosync, cman, rgmanager, ... I guess that answers all your questions?

Thanks for the information, dietmar. I'll familiarize myself with these applications. Have you had any difficulties integrating these tools with the upstream Proxmox? Should we expect to have to make any changes on our hardware arrangements to support them in Proxmox 2.0? I understand from other post threads that the Proxmox 2.0 clustering has been re-written.

It's a complete redesign of the cluster architecture - many changes.

No. You only need some kind of fencing devices.

I know that's perhaps a stupid question but could you already say something about the release date of PVE 2.0?

Hi all,

I have a perhaps more practical question about HA for KVM guests.

Will HA be available without the strict need for shared storage solutions?
To put it in other words, will it support a "drbd-like" (but not necessarily done using drbd) vm replication?

This -in my humble opinion- would be a killer feature, way more important than a UI revamping (the UI already seems clean and fast to me).

Best regards

I guess yes.

Ceph?

You will be able to use any shared filesystem (as long as it is supported by the kernel).

Any expected release date for this? I'm just holding the launch of 2 servers... Bosses wanted me to go after a Xen based solution. But I like Proxmox VE a lot...

See our roadmap.

Hi,
Any beta release for test?
Any date to launch the release?

Thanks for your answer.
