Hi, this doesn't look like a separate network. We regard a separate cluster network as one which sits on its own set of physical network interfaces, so that only corosync communication packets are passing through it. In your case, if the three VMs have the IP address 21.x.x.x (e.g. on vmbr0)...

Note that with a fresh installation, it's recommended to go for Proxmox VE version 7, as Proxmox VE version 6.x will reach "End Of Life" status in July of this year [1]. Would you mind posting your network configuration? cat /etc/network/interfaces Was this carried out after making changes to...

These logs look like a separate issue. Could you check if the file '/etc/aliases exists and contains content? If so, you can rebuild the database (/etc/aliases.db) with the command: newaliases Does login via SSH generally work? If the GUI reports any particular error message, would you mind...

Hi, you should have a look at section "3.3.6. Masquerading (NAT) with iptables" of the Proxmox VE administration guide, which discusses this kind of NAT setup. Basically, your vmbr1 config would look something like: auto vmbr1 iface vmbr1 inet static address 10.0.0.1/16...

Are you sure that you're using grub as a bootloader? With ZFS on root, there's a good chance that you use systemd-boot [1]. Could you post the output of: proxmox-boot-tool status? You should be able to use proxmox-boot-tool to pin a kernel (see proxmox-boot-tool help): # proxmox-boot-tool kernel...

It could still be a DNS configuration issue. Are you able to ping "proxmox.com"? Could you post the output of: cat /etc/resolv.conf?

Hi, Does this happen for every VM? Could you post the config of on of the VMs (qm config <VMID>)? Is there an entry in the task log for the failure. If so, please post the task log also. Finally, could you use the following command to print incoming system logs in real-time, then attempt to...

I'm not sure where the 'hash_elasticity' option is coming from, but that message is only informative. Do you see any interfaces in the GUI yet? If not, could you post the output of ip a?

Which version of Proxmox VE are you currently using? If you have Proxmox VE 7.x, could you try running the command ifreload -a to see if the interfaces file gets loaded? If it's version 6.x or below, you may need to reboot (or install the ifupdown2 package and run the above command).

Oh the guide sets up Plex in a virtual machine inside Ubuntu, so you need to set up nested virtualisation on your Proxmox VE host(s). We have a guide for this here: https://pve.proxmox.com/wiki/Nested_Virtualization

Is Proxmox VE nested within another hypervisor or running on bare metal? Does the message to enable KVM occur on the host (Proxmox VE) or within the Ubuntu virtual machine? Could you post the output of: pveversion -v lsmod | grep kvm journalctl -b | grep kvm

This panel takes configuration data from the file '/etc/network/interfaces'. If this file exists at the moment, would you mind posting it? It's possible that network manager edited the file automatically, or moved the network configuration somewhere else, e.g. /etc/network/interfaces.d. For...

Okay, if it was an update from the GUI, it was likely a minor update anyway. Ah, this explains it ;) The directory /var/log/pveproxy and its contents should be owned by 'www-data'. Can you run the following command to see if it fixes the issue? chown -R www-data:www-data /var/log/pveproxy

Could you also post the output of? ls -ld /var/log/pveproxy ls -l /var/log/pveproxy Additionally, what version did you upgrade from?

Hi, What user did you run the command as? Could you post the output of: pveversion -v systemctl status pveproxy systemctl status pvedaemon Can the server still be accessed via SSH? I would change this back to '640', as it shouldn't have anything to do with the issue. Best regards, Dylan

There's nothing entirely wrong with doing this, but it depends on what you prefer. The difference will be that on the lvm-thin volume ('data') offers block-level storage with thin-provisioning and snapshots, so the slightly higher performance 'raw' drive type can be used and each VM will get its...

This quote is somewhat misleading. ZFS doesn't actively/automatically shuffle data around drives. Instead, ZFS uses up to 50% of the system's RAM (depending on availability) for a read cache. This cache is named ARC (Adaptive Replacement Cache). Additionally with ZFS, you can also configure an...

PVE rrd data is stored in /var/lib/rrdcached/db/. If you remove all the directories (pve2-node, pve2-storage, pve2-vm) within this directory, all statistics will be reset, and new directories will be created upon the next poll. Note that this is part of the cluster file system, so contains the...

The bandwidth option imposes a limit on disk I/O during the backup, so it's not a general limit on VM disk IO, but it would cause additional slowdown during the backup.

At the moment, there isn't. However, you can configure a bandwidth limit for vzdump to reduce the load on the NFS server. See the 'bwlimit' option for vzdump [1]. There has been previous discussion regarding the topic on our bug tracker [2]. [1]...
