Hello, My NFS storage is an DRBD HA NFS "cluster" so i'm looking for the right settings in terms of performance and, above all, resilience in the event of a ‘Primary/Secondary’ switchover. There is not a lot of information on this page https://pve.proxmox.com/wiki/Storage:_NFS Here my...

I tested failover on a new HA ceph cluster all 3 nodes are online but the VM that migrated to the 2nd node from the 1st node will not migrate back to the first node and when I do a manual migration it will not stay in the first node. I removed and re created the HA group and it is still doing...

Example - I have 3 server and Ceph for Proxmox HA. It is using 1 Disk per server. Now, if I have to add a new VM to its isolated storage on 1 new disk per server, but I want that VM to also have HA feature. Is it possible that I can have VMs working on two different Ceph and can work with HA...

New to Proxmox I just set up a cluster of two servers with a quorum device, I feel I may have made a mistake my intention was to use replication and HA between the two and as I was installing I came across a few threads to say if you"re going to use ZFS just do the whole thing and once you're in...

Hi, Let's say I have three technically identical nodes and want to run three Windows servers (dc-1, dc-2, dc-3) with high availability. Is it a good idea to distribute these three servers across the three nodes? Apart from load balancing, in the event of a node failure, only one server needs to...

Hi, Using Proxmox VE with HPE Alletra 5000 as storage: is it possible to configure Proxmox VE to enable high availability (HA) using HPE Alletra 5000 storage? our client plans to connect 30 nodes to the HPE Alletra 5000 with the HA feature. Thank you

Hello, I work for multiple clients and one of them wanted us to create a Proxmox cluster to assure them fault tolerance and a good hypervisor that's cost-efficient. It's the first time we put a Proxmox cluster in Production environment for a client. We've only used single node proxmox. Client...

Dear forum members, I have encountered several questions regarding the operation of High Availability in Proxmox VE and would like to discuss them with you: Why does the pve-ha-crm failover process exceed a processing time of more than 60 seconds, with a significant increase in CPU usage...

BACKGROUND I work for a small business that provides a 24 hour service on our servers and requires as close to 100% uptime as possible. Our old IT company sold us 2 identical Dell R420 servers several years ago with a single 6 core processor, 4x 3.5" 600GB 10K SAS HDD in RAID10, and 16GB RAM and...

Hi, looking into proxmox HA at the moment - our situation is we have a few critical VM's running across multiple clustered nodes. We'd like to be able to have HA on these so that if one of the VM's dies, it is brought online on another node automatically. Is that feasible or is it only if the...

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...

Something went terribly wrong last night. Apparently one host lost connectivity (because of backup) and HA decided to move the LXC client to the first host on DataCenter list (which does not have same storage.) Entire LXC client just went poof in the air. Oct 13 00:00:17 TASK ERROR: could not...

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...

First of all, you can recognise watchdog induced reboots of your node from the end of last boot's log containing entries such as: watchdog-mux: Client watchdog expired - disable watchdog updates kernel: watchdog: watchdog0: watchdog did not stop! You should probably start with reading the...

I am building out a 3 node cluster for home lab use. Each node has (2) 2.5 gb nics which currently plug into 1 gb ports on my switch, (2) SFP+ ports, and (2) 40 gb ports. I currently have the 40 gb configured in a mesh network. I would like to separate everything out to avoid network...

Hi vGPU is getting more and more important. Its nice if it works but what when it comes to an HA situation and the main server fails? The essential functions should be available with live-migration. Please vote for my requests in bugzilla or feel free to write other solutions / ideas: 
 For as...

Hello! My goal is to have HA configured in a way where when a node goes down, the VM's get migrated to any other node that is available. When I set all nodes as the same priority the VM's go into a frozen state and do not get migrated to another node. When I have a node with a higher priority...

I love Proxmox's ability to make it super easy to set up a three-node HA cluster with Ceph. I like to use it for my VMs and SQL databases that require a lot of IOPS. This way, if one of the nodes goes down, my SQL DB VM can be quickly redeployed to another node. That way, if one of the nodes...

Heey I am a newbie to the community, so sorry if it sounds stupid, I have set up an HA proxmox cluster with three zimaboards on my local network that run a couple of VM's in failover mode. Now, the problem is this. When my house lits fire the whole system will collapse. Or when my router or...

Hello, Recently I created my first 3 node proxmox cluster. And I started experimenting. I have two questions that bother me: I've created replication jobs every 2 hours for one VM. Now if I shutdown proxmox node manually on which VM is running let's say 15 minutes before next sync, will the...
