  1. New to Ceph; looking for suggestions for a 3-node cluster

    Hey all; I've made use of Proxmox for a while and I'm looking to take my first few steps into ceph -- I have 3x QCT QuantaGrid SD1Q-1ULH that I will be making use of. Each of these nodes have a Xeon D-1541 with an OCP Mezz 10Gb SFP+ (QCT Intel® 82599ES dual-port 10G SFP+ OCP mezzanine) and...
  2. HA NFS service for KVM VMs on a Proxmox Cluster with Ceph

    Hi, we are migrating from a VMware ESXi setup with a NetApp NFS based shared storage. We also did use NFS filesystems for mounts like /home or /root and application filesystems like a shared /var/www within our virtual machines and host-specific filesystems like /var/log. Most of our...
  3. Best available HA solution with 3 servers

    Hello, I have some doubts on how High Availability can work in ProxMox. I'd like to create an HA enviroment to host my personal websites and also to lear more about HA. I imagine I have 3 identical server and all of them are part of the same cluster. I read about HA with local storage, shared...
  4. [SOLVED] What's the point of a Separated cluster network?

    Hello. I've set up a cluster with physically separated cluster network but it is not doing what I expect it to do. Here is my lab: [node1 ~]# pvecm status Cluster information ------------------- Name: clustest Config Version: 3 Transport: knet Secure auth: on Quorum...
  5. [SOLVED] iSCSI multipath

    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...
  6. dockerd: sync duration of 1.x, expected less than 1s

    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...
  7. [SOLVED] Correct way to restart a node without stopping containers or vm's

    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...
  8. HA for replicated VM

    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...
  9. [SOLVED] lrm (unable to read lrm status)

    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...

    VM migration sometimes fails on host reboot/shutdown

    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...
  11. [SOLVED] pfSense in a VM with HA

    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...
  12. Live Migration PVE 6.0

    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...
  13. [SOLVED] Migration With HA Enabled Dont Respect Destination Node

    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.
  14. Always On VMs / Containers

    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...
  15. multiple NFS storage setup for HA cluster & simulate a failed node

    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...
  16. Cannot delete HA resources since PVE 5 to 6 update

    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...
  17. [SOLVED] cluster network and storage network

    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...
  18. PVE nested virtualization

    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...
  19. [SOLVED] Node configuration

    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...
  20. PVE 5.x - Is HA possible with RRP?

    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...
