ha cluster

I have troubles with upgrade to PVE 5.4, it launches /bin/systemd-tty-ask-password-agent --watch on several occasions and hangs forever. It happens when configuring pve-ha-manager and pve-manager packages. Freeze during pve-ha-manager is especially painful as it leads to unwanted reboot when HA...

I'm trying to add some HA config to my cluster, but the HA tab is locked due to an error saying: "unable to read file '/etc/pve/nodes/dog/lrm_status' (500)" "dog" is an old node which I have since removed. Any idea where I need to remove some config in order for PVE to not look for this config...

I am trying to setup the best minimum scalable HA setup and Configuration. I read the documentation on High Availability, however I have some questions that are not well discussed in the documentation. I was thinking of starting with 4 servers: 2 x front end server that will use a central...

Hello Community, after backing up (proxmox backup function) about 120VMs in a 4-Node-Cluster via NFS, a few (~20)VMs shows the HA in error state. The affected VMs still running fine and there was no trouble at all while running the backup. All VMs are managed by HA. Here are the notifications...

Hi, I am curious to ask if anyone can comment. I'm looking at setting up for a client, a modest sized Proxmox cluster. It will be running on OVH hosted environment, ie, we have access to various pre-configured server builds and my goal is to get a config which optimizes (monthly spend, features...

Building a small home lab HA Proxmox/Ceph cluster with 3 Dell 210ii boxes. I'm trying to do it on the cheap and have decided to forego a 10Gb ring in favor of LACP'd 1Gb based network with quad port intel cards in each of the three boxes and an HP 1810G-24 switch. Due to ignorance I was...

We are currently running tests on a new three node HA cluster configured with 2x10G networking and shared (Ceph) storage. We are using the latest stable packages for Proxmox 5.3. The behaviour around reboots of servers is nowhere near as smooth as we would like. These are the issues that we...

Hello, i read this morning this email form one of my nodes, now,everithig is online, but vps flagged with HA are migrated. My node "cvs2" show me an uptime of 2 hours .. I have tried to migarte back on cvs2 and works well.. What's happened ...

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...
