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'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...

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...

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...

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'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...

What determines the size of the local storage on installation? Does it scale? I notice if installing to a 1TB disk, it uses about 100gb for local. Installing to a 240GB disk uses 58GB for the local. I want to do some installations on bigger disks but I don't want a gigantic local drive on them...

I have a 3 node cluster that I normally access with the Proxmox for Android app. I'm suddenly having a weird issue after logging in. I get assaulted with repeated msgs saying Failed Assertion: boolean expression must not be null I'm not sure what it means, how to correct it, or how it was...

I believe I may have inadvertently broken something related to noVNC inside my Proxmox. Today, I created SSH keys for all 3 nodes, generating keypairs. I have a feeling this broke something, as I overwrote the file ~/.ssh/id_*.pub.ssh/id_*.pub when generating the keypairs (were there Proxmox...

I have a a couple of dozen clients utilizing VMs on my Proxmox cluster. I've made a practice of always setting resource limits for VMs, at half the core count. So if it is an 8 core VM, I will set the CPU Limit to 4. I have a client using 4 Windows VMs, maxing out the CPUs with something Twitch...

I'm still pretty new to Proxmox but have been learning rapidly. I have concerns with some user's VMs utilizing large, continuous amounts of CPU. I have been only allowing 75% for the CPU Limits (eg. A 4 Core VM will have a 3 as CPU limit. a 2 Core VM will have 1.5 as CPU limit). I've also been...

Backups are very fast as long as one has been performed already but I am suffering from very slow restore times. Restoring from a backup seems to takes hours on end for VMs (300GB VM disks with about 150GB of data used) and I'm wondering if this is expected behavior. All disks are SSDs. If so...

I'm curious about the actual meaning of the IO delay in the Server's Summary. For example, when I clone a VM from a template, I expect high IO. All my clone templates are on it's own dedicated drive. When I clone a VM from one of these templates, the IO delay for the node hops up as high as...

After a reboot, I noticed the system log on one of my nodes being spammed with this. Where can I find this log so I can figure out the issue? Jun 10 18:00:01 server2 pmxcfs[1169]: [status] notice: received log Jun 10 18:00:08 server2 pmxcfs[1169]: [status] notice: received log Jun 10 18:00:18...

IPSet doesn't appear to be working, as I can still switch the IP from inside the VM to any IP in the block. Firewall is on in the Datacenter as well as on the Node. Am I missing something? Firewall settings for the VM are below (I thought I had this working properly already but it seems I was...

I'm having an odd occurrence. When creating a WIndows VM, if I set the cpu to Host, the installation will proceed normally but then at the end will result in an infinite bootloop when trying to restart after install. If I use KVM64 or Qemu64 this does not occur. I've noticed if I complete the...

I have 2 Proxmox nodes in my home lab. The first is a Dell Poweredge r710 w h700 RAID, 72 gb ram, SSD disks. This is the machine I am having issues with. Linux based VMs run perfectly, with no issue. Window 2016 VMs misbehave in odd ways, most notably terrible network performance as regards to...

I used to love the PVE for Android app, but after the last PVE update, my individual node's cpu usage is always incorrect. It stays at 0.07% always. Is there something I can do to remedy this, as I prefer the functionality of the app compared to the mobile site?

I'm a bit new to Proxmox, so forgive me if this was already discussed. I'm wondering if there are some general guidelines concerning CPU usage on a single node. I have a 2 node cluster, one of the nodes running several VMs of different compositions (vms that are strictly databases, some are...

I'm very new to Proxmox and Hypervisors in general. VMs install and run with no issues when the CPU type is set to Default KVM64, but setting to Host (or if I specify the processor type as Westmere, which it is, it errors the same way) will result in an error when installing OS after the reboot...
