I'll try that. Thanks!

Hey, I first have to set a network device from my VM to the Host, which has an IP adress in the Host segment... I think that's the problem

Do you have an example how I could possibly use the returned json? Especially for pvesh get /cluster/ressources to store the value on which host the vm is running in a variable.

Is it possible to save the value that is being returned by pvesh in a variable ?

Hey guys, I can't access the Proxmox API from the VM, only from my host... How can that be changed? Thanks!

Hey guys, in my environment it is possible to perform a ping between the nodes in the cluster. Nevertheless I can not ping a node in the cluster from my VMs. Do you know how to solve this issue. Thanks!

Isn't a cluster with a even numer of nodes causing a lower resiliency to failures than one with an odd number?

Hello guys, I'm currently using a 4-HA-Node Cluster, which isn't really perfect due to its even number of nodes. That's why I was wonderng if it's possible to use the fourth node as a Cold Standby, without losing redundancy? Basically the forth node would be switched off and I still could lose...

I see your point guys, that helps me a lot! So i case of HA there isn't really no difference between a 3 and 4 node cluster? The availability and performance is nearly the same?

Like I said my 4-Node-Cluster is still quorate when it looses two nodes and ceph is also accessible. It works.

Thank you for your fast reply - I understand your concern when it comes to quorum. But here is the thing, votequorum regulates the needed votes for my cluster: When I have 4 - the expected number of votes is 3. When I shutdown one node it needs 2 from 3 active ones. When I shutdown the third one...

Hey guys, I'm currently running a 4 Node HA-Ceph-Cluster and I was curious about testing the fault tolerance of it. According to my observations the cluster itself is still accessible, even with two remaining nodes (due to the changed config of votequorum) Which configuration do I have to make...

I really like your explanation and think that I understand the difference between both. Also thank you @dietmar @tom

Thank you Tom, but I know this document already and didn't found an answer to my question there ...

Your wiki defines pvecm as cluster manager: https://pve.proxmox.com/wiki/Cluster_Manager. This magazine defines ha manager as cluster manager: http://www.admin-magazine.com/Archive/2017/42/Proxmox-virtualization-manager That's the reason why I'm a little bit confused. Neither there is real...

What is the Clustermanager in Proxmox? pvecm or ha-manager?

That's not really the answer to my question

Hey guys, I understand that we use pvecm to create and manage a cluster. Furthermore the purpose of the ha-manager is to do automatic failovers etc. But what is the main Clustermanager in Proxmox? How do pvecm and ha-manger (lrm and crm) work together? Thanks!

But waiting 3 minutes for a VM to come up after a immediately poweroff, is not acceptable in HA environment!

This only works for a controlled shutdown, but when you perform a immediately poweroff of the node (e. g. plug off the power supply) the VM won't be migrated.....
