high availability

Hi, We are trying to deploy an HA storage environment on Proxmox using multipath, a Synology NAS (RS1619xs+) and an iSCSI SAN, and we cannot get the multipath driver to manage the iSCSI LUNs. We need a little help to go further or to interpret the errors we are commiting. This is what we are...

I've had this problem for a while here now, and I've turned the internet upside down trying to figure it out, but there is very, very little information out there about this specific warning. It is extremely consistent and reproducible in my PVE setup though, so I figured I'd ask here! May 28...

Is there a correct way to restart a node (mostly for applying kernel updates)? I have about 20 virtual machines and containers that should not go down ever unless planned. So I have set the all as HA. When I shutdown a node, the VM's / LXC's shut down instead of migrating to the node next in...

Hello I have read documentation and topics on forum about this subject but cannot find a clear answer (and the thread How does Replication work in a HA environment? is quite old , 2017) If I have a replicated VM betwen the 2 nodes I'll put this VM in HA configuration, Will HA process use the...

I had a server die this past week and I removed it from the infrastructure. I can confirm that the server is out of commission and is pulled from the rack. I removed the node and all is well, or so I thought. The cluster is giving me an issue with regards to it seeming not being able to find the...

Hello, We have a 8 servers Proxmox 6.1-5 cluster (last updated 2 days ago) that is configured for HA with "shutdown_policy=migrate". However we noticed that this sometimes works and sometimes doesn't, having a VM with HA enabled running on a host that is rebooted or powered off can result in...

I'm trying to figure out how I could install a pfSense VM and make it HA. I have a ceph cluster of 4 nodes (but there will be nodes added regularly), so I can give each node a public IP address on one of it's ethernet ports. Creating a bridge and adding that to the pfSense VM will give me a...

Hello Proxmox Community, I am interested in live migration. Recently I read posted accorss the fron the XCP-ng's website the phrase "Live migrate your VMs all around the world, without interruption" However I did not find any detailed sources which stipulate that live migration was actually...

I have an LXContainer that I want to migrate to node3. If I have HA enabled for that Container, it will always migrate to node1, regardless of the selected destination. The container is on shared ceph storage.

I'm new to Proxmox and I'm a little lost. I have the system setup, Client side resources (VMs / Containers) fail back n fourth and i can manually migrate. The problem I have is when a node is down, a resources sessions are terminated and that resource is shutdown, migrated to another node and...

hi all! I have 3 nodes in HA cluster using Proxmox 5.4 . The nodes use the public IP for cluster communication and the private network for the storage network. Each node has an NFS storage shared with the other nodes. The disk in all 3 nodes are in RAID 1 (mirroring) (the reason i cant use ceph...

Hello, I come accross a difficulty with the HA management since we have updated our 3-nodes PVE cluster from 5th to 6th version. We did of course follow the Upgrade from 5.x to 6.0 wiki page, so deactivated both pve-ha-lrm and pve-ha-crm services on all nodes before the update. The pve5to6...

hi everyone! We are migrating our server to a different cloud provider. While reading a documentation, i read this: "Storage communication should never be on the same network as corosync!". Our server must have HA and data redundancy/ data high availability (using ceph). The problem is, our...

Hi all. Im very new to proxmox but i need to simulate a cluster in my physical [proxmox] server. Reasons for doing this simulation/test are : test HA, test live migration, test ceph storage, 4 nodes HA amongst others. Here are my objectives (feel free to tell me anything i missed): a...

Hi all. I wanna ask a few questions: 1. if proxmox nodes in HA cluster must have the same specs (ram, cores). Ive read the documentation for HA but im not sure if it is implied that nodes must have the same specs. i will create a test cluster anyways this week, but would save me time if i have...

Hi all! I tested rrp in our test environment with ceph. Two physical separate network switches, one for cluster network (the nodes 10.10.10.0) and one for ceph network (172.16.0.0). I had the same experiences like the others described; if cluster network on one node is broken or offline, the vm...

I noticed that there's a new feature under the pvecm command to add a qdevice. I have been using Proxmox at home and for clients in a single node local storage configuration for almost a year now, and have been dying to mess with a proper shared storage/two node HA setup. My dream setup would be...

Hello! I have a 7 node cluster and a software/lrm HA. I have just done maintenance on one of the nodes and have rebooted it. Due to some hardware failure it failed to boot. The VMs that were on that node are in a frozen (HA) state and I can not migrate or start them. Is there a way to convince...

Hi, I have read just about every post on this forum on this topic. Some have some useful information, but I can't get all the answers that I have questions for, hence this post. I need to setup a 3 node high available cluster to host 14 virtual machines, Linux and Windows based. This is to...

Hi, I know from VMware vSphere three functionalities Admission Control Policy Takes care of redundancy (e.g. one host can fail and all VMs can still run and/or be restarted on the remaining resources) New VMs cannot be started or deployed if the resource is full High Availability I know...
