high availability cluster

Good afternoon. I have a production HA setup with shared iscsi. I fear I've misconfigured things and am stuck with the poor performance I'm experiencing. I have 5 HA hosts. 4 active with guests and #5 for voting only. - Each is dual port 802.3ad LACP bound 10 GIG MTU 9000 - HA configured iSCSI...

Merry Christmas, everyone, if that's what you're into. I have been using Ceph for a few months now and it has been a great experience. I have four Dell R740s and one R730 in the cluster, and I plan to add two C240 M4s to deploy a mini-cloud at other locations (but that's a conversation for...

Ich bräuchte einma einen Rat aus der Community: Ich baue in meinem Unternehmen einen zwei Node Cluster mit (wahrscheinlich) einem Q-Device auf. Meine Frage wäre, ob es möglich ist auf beiden Nodes eine gleiche Menge von VMs zu verteilen und dann trotzdem noch Ausfallsicherheit und die...

Hallo Zusammen, Im Proxmox Cluster ist eingestellt dass VMs über HA migrieren sollen, wenn ein Knoten down ist. Dies hat allerdings bei einer Node mit vielen VMs zu einem unerwarteten Verhalten geführt. Die Migration ging sehr lange, und bei ca. 50-75% migrierten VMs ist der Knoten einfach...

im currently using hyper v and have some clusters setup. ive only just started tinkering with proxmox on a single server, and currently have 3 identical servers, and 2 others that are different. if i moved all servers over to proxmox would they all work together without any issues or would they...

Hi i am about to deploy a 7 host proxmox cluster and want loadbalancing. Ive read alot about CRS but to me its unclear whether CRS is only used for bringing up HA machines or whether it can handle live migrations to loadbalance my servers any help is appreciated

Hi everyone, I'm experiencing an issue where NODE1 in my Proxmox VE cluster is restarting when both NODE2 and NODE3 are powered off, even after I've made several adjustments to the corosync.conf configuration. Below is a summary of the setup and the steps I've taken: Configuration Overview...

Hi all, i managed to configure Proxmox with a fiber channel SAN (HPE MSA2062) and multipath-tools. Everything is fine until i reboot, everytime the disk is showing LVM2 Member instead of mpath_member. After that when i migrate or create a VM, i have an alert that i'm accessing a multipath...

Hey all, we currently have a 1-Node VMware setting in one of our locations which runs two VMs with one sporting SQL Express (currently still 2017) whilst the other has a Pervasive SQL database. Backups are done via Veeam to an external storage at a separate location via "broadband" (quite...

Hello Proxmox Community, I'm writing to get some advice on a Proxmox cluster project involving two main homeservers and a third site for backup storage. My aim is to enhance individual service availability by using already available hardware and high availability (HA). Both main sites host...

hi guys, i have a cluster of 3 8.2.2 nodes. As a shared Storage i configured successfully the ceph cluster. Everything works fine, migrating a vm to another host works fine without interruption. But in case i turn one node the vm which ran on it took about 4 minutes to get online again on...

Morning Everyone, I was looking deeper into the High Availability States and I thought at first I misunderstood the directions but the options are for Start, Stop, Ignore, Disabled. Start forces a startup, stop forces shutdown , ignore allows for manual start and stop but no more resource...

Hello all, I have a configuration that utilizes SR-IOV to create VF's that are then passed to my VM's to allow high speed traffic with no additional overhead. When trying to migrate it complains about the local device. All nodes in my cluster are identical, i wanted to know if anybody has...

Hallo, ich habe bisher Proxmox auf einem gebrauchten HP ProDesk laufen mit ioBroker und Home Assistant. Läuft alles super. Proxmox VE 8.2.2. Ich möchte mich nun mal mehr mit der Hochverfügbarkeit beschäftigen. Ich habe noch einen Raspberry Pi 4 rumliegen, den würde ich als QDevice nehmen...

I am having a dilemma with my server configuration, namely I have 2 servers running at Home. Problem Statement: I am considering to setup 3 node Proxmox HA Cluster with CEPH considering all 3 nodes with same specs as Server 1 (given below). If I were to do this, what kind of performance gains...

I want to learn SDN and see how I can implament it into my current 4 node proxmox cluster. I've had a look at the proxmox documentation and the information isn't sticking. Just wondering if anyone knows a good youtube video on it that talks about all its features and how to use them.

I'm quite unsure of what is happening. I've been struggling with this for the last two weeks. So I've installed proxmox on my home machines. My gaming PC has a GPU passthrough working well enough, and my Windows VM feels like a natural PC with all my USB ports forwarded and everything. I even...

Hi, I am thinking to add 2 mini pc nodes with dual NICs and create my first ever proxmox cluster. I am already running pfSense on my single node. to do HA on pfSense, you need a sync interface. This would mean that I need 3 network interfaces: WAN, LAN and Sync Since I have only 2 NICs...

I learned that we need one Internal IP for HA data transfer and one for public use IP. I am not sure how it works Please suggest. Do we need two network cards per server? (Dual Port 10GbE for HA and Dual Port 1GbE for other use)
