Hmm, all nodes can ping each other. So networking doesn't seem to be the issue.

So, there is no way to do this? Do I need to tear down everything and create a new cluster?

Hi, I have a three node cluster in my home lab that was running on PVE 8.1.5. Now I upgraded the first node to 8.2.2 and, after rebooting, it doesn't connect to the cluster anymore. The remaining cluster can't see the upgraded node and the upgraded node can't see the remaining cluster. Did...

Any ideas, suggestions, experiences?

Huh. That's an important question. Should have asked that before I went down that route... Unfortunately, I can't tell yet, it's still in the box.

Well, that 's the problem, isn't? I have a three node cluster. So I take the first node offline to replace the networking hardware. The remaining two nodes should be able to keep the cluster running. I restart the first node but it won't be connected to the cluster yet. Then I take the second...

Hi, I have a small home lab cluster with 3 PVE nodes each of which also serves as a Ceph node. For each, cluster sync and ceph, there is a dedicated 10gbe network (and then there is another dedicated 10gbe network to a PBS which sits outside the cluster). Now I want to upgrade the network to...

Okay, so I have all the stuff ready. Now the question is, how do I replace the network on my cluster nodes while they are parts of the clusters (PVE and Ceph)? I can't simply add in the Mellanox cards due to a lack of PCIe slots. But if I take out the 10gbe cards and put in the Mellanox cards...

Tried again today (did not try in the meantime). Same behavior: Came back very quickly with the same error message. Pretty sure no cleaning was done. So what does "Cleaning cartridge installed" mean? If it said "No cleaning cartridge installed" - that would make sense (although I do have one...

That's a good price. Alas, they don't ship here... Same with them. But I have found a place that does ship here. Shipping costs almost as much as the switch but that still is cheaper than buying it here... I read on some forum that it isn't easy updating the firmware. Is that really a problem...

While I need to test it more, I gave the .link files another chance (https://wiki.debian.org/NetworkInterfaceNames#CUSTOM_SCHEMES_USING_.LINK_FILES). Somewhere in the long article @mow linked above, it says to not use names that the system would use (like "eth0"). Before, I had used "eth0" and...

Is bandwidth fever a thing? Because I think I'm feeling it ;) With a quick check on ebay, I found a couple sx3036 but, alas, at substantially higher prices. Probably need to watch that space and strike in a good moment... But I also found sx6015 and sx6025 that are quite affordable. Main...

Would it please be possible to get a statement from the good folks at proxmox whether this is [ ] out of the question, [ ] on the roadmap, [ ] already being implemented, [ ] a stupid idea, [ ] ... ? ;)

So I managed to get this working after a (long) while. ABut yesterday it stopped working again. I don't know why but my best guess is this: When I installed the Grid drivers (both on the host and in the VM), I needed to also install the respective kernel headers and make utilities. So while I...

My current working hypothesis is that the interface (I think it happens to only one of the two) changes its name upon a reboot (as opposed to a shutdown and restart). I don't have enough data points to support the hypothesis yet but I will observe. And I don't know if it helps to know that is is...

Hi, I want to get my feet wet in machine learning / artificial intelligence and for this purpose I have bought an NVidia RTX A5000. Unfortunately, this card requires more power than my small home lab servers can deliver with their measly 450W PSUs. So at the moment it lives in my workstation...

Thank you for this suggestion. These cards are indeed ridiculously cheap. I shall investigate this further. My first impression is that Infiniband is the better technology - would you agree? I do, in fact only have a small home lab cluster of three nodes. But I am a bit reluctant to wire them...

It happened again! Last time I booted, eth0 (or was it eth1?) was renamed to eth2. Today, I have back eth0 and eth1. Thank you for the suggestion. I did check dmesg but all I found was: e1000e 0000:00:19.0 eth0: renamed from eth1 No hint as to who or what renamed it... Yes, they don't...

Can someone recommend "cheap" (ideally quad, at least dual) network adapters and switches that support 40gbit? Are there any options with rj45? Looking to buy used. Thanks!
