Props @daniel6, you saved me a major headache. A node got fenced during `apt update` and left networking in a non-working state.

@vesalius this was the secret sauce I needed. Brilliant, thank you! I still struggle with the networking config, thank you for making it more clear to me.

Thank you for your quick response. I tried your suggestion, however, it's still erroring: error: vlan10: cmd '/bin/ip route replace default via 10.10.0.1 proto kernel dev vlan10 onlink' failed: returned 1 (Cannot find device "vlan10") This is the configuration with your suggestions in place:

Need to revive this thread again with another hopefully simple question. I'm working on a completely different cluster, trying to create a VLAN bridge called External near the bottom of /etc/network/inferfaces as I did successfully above. Inexplicably neither version of the interfaces config is...

Post your /etc/network/interfaces file from the Proxmox host. What's the output of brctl show and bridge vlan show from the Proxmox host?

@shanreich Well, you were right all along. Config 1 with your suggestion worked. I have been fighting against a misconfigured DHCP server this whole time and it was handing out IP addresses on different subnets. I've corrected the DHCP server issue, and now the bridges are working. Thank you for...

I've spent way too many hours on this at this point messing around with dozens of /etc/network/interface configurations. I have concluded that unless I specifically tag the VLAN at the VM's nic (as pictured below), tagged traffic won't flow, despite supposedly the Phones bridge being configured...

Great, thanks for the clarification. Now if I use, for example, the Phones bridge on a VM, I would NOT need to tag it, correct? This is my ultimate goal. Later Edit: when I do bridge vlan show I can tell that Phones is not sending tagged traffic on 1110. So I would have to tag at the VM...

Hey all, Been working on setting up some VLANs as bridges at the host level. Typically I simply add the NIC to the VM, then VLAN tag it there, however I want to try to add the VLAN to the host as a bridge, and pass tagged traffic through a bridge to the VM from there (kind of like VMWare)...

Sometimes I run into issues with hidden characters getting pasted in when I paste formatted text into the console. You can quickly remove any of these hidden characters with sed in this Bash command: sed -i -e 's/\r$//g' -e 's/[[:cntrl:]&&[^\n\t]]//g' /path/to/your/script.sh This will: Remove...

That worked, thank you! I was able to patch the file and add the qdevice. A few more details for others peace of mind, since I've never patched like this before: I needed to install patch with apt update && apt install patch -y (doing this on one host will suffice). Created file containing the...

Few months late, but yes, the recommended change is to set KillMode=mixed. Here's an explanation of each mode, from www.freedesktop.org systemd.kill: KillMode=none: No processes in the control group will be killed. This setting is rarely used because it can lead to orphaned processes that...

Any idea when the solution to https://bugzilla.proxmox.com/show_bug.cgi?id=5461 will be merged and available? Having the same issue over here.

Thank you for sharing your solution @iay. I faced a similar issue and resolved it by disabling IPv6 on my Synology device. I was able to kick RRD back into gear without having to reboot my hosts by logging out of the iSCSI session then logging back in. Here are the basic commands (can also be...

Love it, thanks for posting your solution too!

I'm still seeing this in the syslogs (Nov 2023) so for what it's worth you can silence the error with sudo nano /lib/systemd/system/ceph-volume@.service Locate the line KillMode=none and change it to mixedor control-group. Make this change on all your CEPH nodes. When you're done, don't forget...

Thank you so much @RolandK and @johndoe297 for your suggestions. After a lot of trial and error I was able to determine the cause of the problem was most likely a CPU that was overheating, triggering the IPMI (BMC, IDRAC whatever you want to call it) to shut down the system. The strange thing is...

Does anyone know the answer to this?

Hey all. Hopefully a simple question. Which network is used for backups when backing up to CephFs (as configured from Proxmoc GUI)? I'd assume it's the public network, right? I'm using 25Gb fiber nics for my cluster network. Would it be possible to easily set backups to use the cluster network...

I recently encountered a rather bizarre situation and thought I'd share it. I have this server situated in a secure data center where only one other person and I have access. Nevertheless, the server unexpectedly shut itself down. The system in question is a SuperMicro 2028TP-HC0R 2U, outfitted...
