The remote node averages roughly 20ms give or take, which is very appropriate as it is in Virginia and our office is in New York. I've run extended OMPings from all nodes and don't see evidence of any significant packet loss. The reason I've begun looking into this is due to weird downtimes...

Odd. because on Host 4 is says 1 and 2 joined, but on node 1 and 2 it says Host 4 has joined. Host 1 and 2 are here and Host 4 is in a data center. So presumably there is an issue here. I notice host 1 is spamming Retransmits. For host 1, i tried changing nic ports, cables, switches and...

In my SysLogs, I'm seeing the following over and over, anywhere form every few minutes to every hour or so. Apr 22 13:54:55 server9 corosync[3275313]: [KNET ] host: host: 1 (passive) best link: 0 (pri: 1) Apr 22 13:54:55 server9 corosync[3275313]: [KNET ] host: host: 1 has no active links...

I have resolved the issue by running the following commands on the host systemctl daemon-reload and then systemctl start qmeventd.service

I can verify the working solution, as I experienced the same issue as OP and Fiona's solution, systemctl daemon-reload and then systemctl start qmeventd.service, on the host fixed it for me.

Standalone node or cluster? Cluster, but other in cluster are different hardware so this may or may not be a viable test. Yes No. This node is only rebooted once or twice per year. Qemu-guest-agent installed? yes and yes Please provide the full VM-config (qm config VMID) in code-tags of at...

I'm not sure exactly when this started happening, but VMs no longer shutdown in a clean way, whether initiated from inside the VM or via Shutdown signal from Proxmox GUI. On a shutdown, the VM will hang, requiring a Stop command to be issued in order to shutdown the machine fully. Sometimes...

This is a great idea but unfortunately I can not reconfigure the servers in anyway. Best I could o would be SSD via NAS

Power settings don't make appreciable difference in VMs in my testing and experience. Just to note, they are all disabled anyway. It's mainly just an issue of preventing excessive write/read ops on HDDs. Swap is the biggest culprit here.

In order to disable the pagefile in Windows 10, you have to access the Virtual Memory settings. Follow these steps: Right-click on This PC icon on your desktop, and then select Properties. Once you get to the window, click on the “Advanced system settings” link on the left...

I've done allot of research on this but can't find any answers that are satisfying. I want to see what the Proxmox community thinks. I am currently running multiple identical nodes (AMD Epyc 7351, DDR4 2400 RAM, SATA HDD). The bottleneck is the HDD, but we have to make them work. I noticed a...

This is a correct answer. You must run ssh -o 'HostKeyAlias=<Target node Name>' root@<Target node IP> You have to execute this on every cluster node with each cluster nodes as target.

All the metric graphs on my nodes have stopped updating while I am looking at them. The graphs used to update in real time, but now it seems to be a snapshot in time of the moment i look at the node's graphs. If I switch to a different node then back, the graph has updated, but no longer updates...

That's not an option for me, as we use qemu-guest-agent to automatically provision passwords on VM rebuilds and installations. Interesting to know that disabling it is a fix. Maybe could point the devs in the right direction to fixing it.

I have resorted to just using cPanel's daily backup feature. It's unfortunate but it's the best move in my situation.

Anyone with Debian 9 insight please assist. I have several OVH servers and never have problems setting up VMs with internet using their guide. I've successfully and easily setup Debian 10, CentOS 8, Ubuntu 18 & 20, Windows with no issue. I finally got Debian 9 to work on the network but for...

When performing backups on only this particular VM, a CentOS 7 cPanel installation, if there is already a backup present, the VM will hang at the issuing guest-agent 'fs-freeze' command, though the backup seems to continue on after the error. This behavior is not exhibited if there is not a...

I found a solution in a post on here on the forum. Anyone running into this can solve the issue with the solution outlined here. https://forum.proxmox.com/threads/console-failed-to-connect-to-server-host-key-verification-failed.78957/

I've just installed my 6th node in my cluster and am having an odd phenomenon after creating my first VM. I've not experienced this before on any other node and am using the same process I always use when adding a new node. I always access my gui via the node Server 1. The new node is Server 6...

Right. All these things are stored in NFS. I was concerned because if I use a 4TB disk, I don't want 1TB of local. Thanks again
