Hi there! I have 5*ProxMox servers running 5.2-9, one of which has a number of hard drives in them, I would like to share those disks to the other 4 servers in the cluster so that I can run HA. (to clarify, the other 4 servers contain minimal storage that I do not wish to store VMs on) My...

Hi, I have setup a 3-node-cluster that is working like charm, means I can migrate any VM or CT from one node to the other. The same nodes are using a shared storage provided by Ceph storage. I followed instructions and created HA groups + resources: root@ld4257:~# more /etc/pve/ha/groups.cfg...

Hello, i find this entry on my syslog: pve-ha-crm[4037]: service 'ct:405' without node But i can't find this container anyware .. I have chacked on datacenter HA byt i can't find any entry.. Thanks!

I was wondering... The HA feature in proxmox ensures that a VM (or LXC) will start on another node in case a node goes down, but the machine will shutdown and will have to reboot on the next node. Would there be any way to ensure that the machine will instantly appear on the other node once its...

Hi, in a HA enviroment, a mass migration don´t honor the parallel jobs setting in GUI. This is really dangerus, because parallel live migration of >40 VMs saturated the cluster network which ended up in a dead cluster. Is there a way to avoid this scenario like restrictions of parallel jobs...

Hallo zusammen! Derzeit plane ich von Hyper-V zu Proxmox zu migrieren. Da Ausfallsicherheit nun eine wachsende Rolle spielt, soll Proxmox dann im Cluster laufen. Mit mindestens 3 Nodes, richtig? Der aktuelle Server ist sehr Großzügig Dimensioniert: 2 x Xeon E5v4 8C16T 4 x 32GB RAM Zur Zeit...

Hello, please help me to understand how to setup a HA cluster with VMs that should be accessible from the Internet even after one node fails and it's VMs are migrated and started on another node. There are 3 nodes in a cluster (that should become a HA cluster later): - node01 -- vm01a --...

Hello all, I'm hoping you maybe able to help me as I seem a bit in over my head this time. I have three physical servers that I am working to build into an HA cluster. Two of those servers will be the processing power (hereafter referred to as P1 and P2) of the cluster and one is the storage...

Hi, We're testing proxmox 5.2 running the latest enterprise version. We have a few LXC containers running on the hosts and managed through HA. When we reboot a host, all of the containers are started, but their network connections do not work. The only way to re-establish network connection to...

Hi everybody, I'm new to this forum and this is my first post. I am stuck in a High Availability cluster setup. I have the following configuration: - two servers - two storage nodes (qnap nas) with iSCSI support. I want to create an ha-setup where: - if one of server fails the vm still runs...

Hi, I've a cluster of 9 nodes in 3 datacenters that looks like this: DC 3 DC 1 +--------+ LINK 1->3 +---------------+ | P-ARB |--------------------| P1 P2 P3 P10 | +--------+ +--------+------+ |...

I have 5-node proxmox in HA cluster. I wanna know how do the proxmox calculate the resource of Node? Example when my 1st node down, the VM move to the highest-priority node. So when do the VM move to the next-priority node ? ( 80% RAM or 80% CPU of highest-priority node are used, etc....) Thanks...

set CT to "ignore" in the HA web GUI delete CT At that point you have an entry in ha config without a node, which cannot be removed, and keeps logging errors.

Is there a way to restrict the HA relocations to target only a set of nodes? Let's say: the VM1 can only run on SERVER1, SERVER4 and SERVER6, but not on SERVER2, SERVER3 or SERVER5.

Hello experts, I am having this problem not 4th time in same month, my master node in 4 node cluster goes down and even though I have HA setup and nodes migrate but vms are still not reachable. Also is there any way I can also find reason why this is happening. I had to manually hard power...

Hi, I am currently setting up a proxmox (v. 5.1-41) cluster. Since the default behaviour of nodes which can not reach other members is rebooting themselves, it would be interesting to know where I can configure this. Especially setting a limit of how many reboots a server is allowed to make...

Good morning everyone, i just configured my back interfaces (10GbE) of my three new servers. To provide enought redundancy and availability i connected my three servers the following way: Hardware Config: - Every Node has 2 10GbE SFP+ Ports that should be used only for Cluster communication...

Hello all, I am new to proxmox community. I have 2 proxmox clusters with 2 nodes each setup with ceph storage in same local network with Public IPs. Recently one node on one of the cluster died but the secondary node on that cluster did not bring up the VMs. I have done all the research and I...

Hi every one Is it possible to configure HA cluster with three nodes (2 identical physical machines, one VM) and use Ceph only in the two physical nodes So Proxmox 5 will be installed in the three nodes and Ceph only in two nodes I appreciate any help, thank you :)
