Because you successfully sent the first email, your configuration in PVE is likely correct. This means the issue is not in PVE. You might get more information from /var/log/mail.log You should also examine the logs on the Exchange Server. It may have a spam prevention tool that is preventing...

What is the output from pve-firewall status ? Please provide the output from (replace XXXX with the VMID): cat /etc/pve/qemu-server/XXXX.conf And your interfaces file: cat /etc/network/interfaces

Please provide: The interfaces file contents for each host A configuration of a guest that works as expected that is on the same host as a guest whose networking does not work as expected. The configuration of the guest that does not work. cat /etc/network/interfaces Replace XXXX with the...

Please post your guests' configurations (replace XXXX with the VMID). cat /etc/pve/qemu-server/XXXX.conf

Hi @TSAN I was looking for something related to ZFS replication and VSS when I came across your post. Just in case you have not found the answer to your question... Yes, ZFS replication triggers a freeze-thaw with VSS if you have the QEMU guest agent installed. If your database responds to...

@brnogu a few questions: Is VM1 (VMID 105) that is failing to backup to /mnt/pve/NAS on the same node as the other VM that successfully backed up to that share? If they are on the same PVE node, please provide the following: pvesm status cat /etc/pve/qemu-server/105.conf cat...

@Kratus thanks. I have some questions. What are the following interfaces connected to? eno4 ens1f1np1 ens1f0np0 Specifically, are they connected to the same switch? If so, what port number is each interface connected to on that switch? If not the same switch, what are the names of the...

Sorry, I should have been clearer. Your PVE host's /etc/network/interfaces file.

Hey @aj@root ! Thank you for creating this tutorial. I have validated the WebAuthn steps in our lab (already had the certs). Works great! Also, thank you for sharing.

Please provide the contents of your /etc/network/interfaces file. Have you enabled the PVE firewall?

If the traffic leaves the Proxmox VE node tagged correctly, then the issue is with the network gear after the PVE host. Have you checked the switch config?

Sie können Wechseldatenspeicher verwenden: https://pbs.proxmox.com/docs/storage.html#removable-datastores 1. Schließen Sie die externe Festplatte an PBS1 an. 2. Erstellen Sie einen Datenspeicher auf der externen Festplatte. 3. Kopieren Sie den Datenspeicher mit einem Synchronisierungsjob auf...

Yes. That is the correct way to set up the VXLAN. VXLANs work, while VLANs do not, because VXLANs encapsulate the traffic they carry (think VPN, but without the encryption). VLANs tag each packet (actually, they are frames, but you get the idea), and all the network gear between the Proxmox...

Check Datacenter > Storage. Is it still defined there? If so, remove it. In Proxmox VE, storage and the underlying physical storage are separate things.

Ah. Often see that with Dell and HP's older hardware. They released the hardware back before PVE was cool. :-) Then, you need to rely on the drivers in the kernel.

Ah! Thanks for that overview @markf1301 Your architecture makes sense. Yes, having dedicated hardware for PBS is the ideal situation, but there are many use cases where that is not possible for technical reasons or resource constraints (e.g. money, time). Based on what you have mentioned and...

I would try updating the drivers first.

Yes, it looks good. You would need to dig deeper. Might be hardware related. It does seem high. Might want to look into that.

I may not have understood your topology correctly. My understanding was you had a PBS local to your PVE (site #1). Then, you had a remote site (site #2) with a PBS and a Synology together. From this last post, it sounds like you have a PBS local to your PVE (site #1), a remote site with...

Thanks for sharing this information. Please run the following variations on the iperf3 command: # Node1 iperf3 -B 10.xxx.xxx.61 -s # Node2 with extra option "-P 8" iperf3 -B 10.xxx.xxx.63 -c 10.xxx.xxx.61 -P 8 iperf3 -B 10.xxx.xxx.63 -c 10.xxx.xxx.61 -P 8 -R # Node2 with extra options "-P 8...
