I tried that. I rebooted node A without access to the Corosync network (so that it would not mess things up again) and copied all VM conf files to a USB stick. But when I try to copy an old conf file onto node D, it won't let me. It tells me that the file already exists (in...

Hi, I want to shrink my vm disk (I have already shrunk the file system inside. So that's fine). Above, there is a howto for ZFS but my VMs reside in CEPH. What is the right approach here? Thanks!

After I took node A offline again, nodes B, C and D started operating normally again.

Small update: I can now also log in to the GUI of node B when I access its IP directly (all my nodes have LE certificates and can -- normally -- be reached internally via the respective domain names). And when I look into node B's GUI, I see this: Cluster consists of A, B, C, D: B, C and D are...

I have a small three node cluster in my home lab. Everything was working fine until recently one of the nodes ("A") went into a reboot loop (I don't what caused this yet), so I turned it off for later trouble shooting. The other two nodes ("B" and "C") have been working fine since then (Ceph did...

I do have one follow-up question: Now that I know that my normal profile is somehow messed up, is there a way to repair it or am I better off making that new test profile my normal profile and deleting the messed up one?

Never heard of that before. But a new clean profile actually did the trick. I guess I'll have to read up on profiles in Firefox. Thank you.

That's a good idea. But, alas, it didn't help. Thanks anyway.

Hi, I was away for two days and coming back, I can't enter the TOTP in my PVE GUI anymore. Well, I normally use Firefox and with Firefox it doesn't work anymore. But with Chrome it does work still. So I have a workaround. But what is going on? I accces the PVE GUI and then I'm prompted for...

Hah, I never found that. Knowing (from you) that this exists, I now found it (but I had to look several times, because . Thanks! I'm lazy, what can I say. No, so I guess - with my newly acquired knowledge - I can now not only remove the PVE notifications but the entire PVE. Cool! Thanks.

No, PVE doesn't do anything. I only have it there for the GUI features. This is just my PBS with an additional GUI.

Hi, I have PVE running side-by-side to my PBS, mostly for the parts of the GUI that is not implemented in PBS, like updates. And I have notifications enabled both in PVE and PBS. So now I'm getting notifications twice. Is it safe to disable notifications in either PVE or PBS? I wouldn't want...

Hi, I am experiencing issues with one of my VMs currently. For a reason not yet understood, it goes into 100% cpu load and the guest agent is shown as not active. Is it possible to have PVE notify me, if something like this (e.g. high/full CPU_ load, guest agent down, oom, ...) happens in a...

Thank you! modprobe: FATAL: Module rdma not found in directory /lib/modules/6.8.12-8-pve My cards are set to ethernet mode right now. Would that explain this error message (because in ethernet mode rdma might not work)?

Thanks for the hint! I don't think my cards are limited in that way because I have them in eth mode and do reach throughput of 15 to 20 gbps that way.

So I got that Ethernet license as well and switched two of my three cards to Ethernet mode (and, of course, also the switch). With iperf I got a throughput of (close to) 30gbps. Not bad! Or so I thought. I switched also the last card to Ethernet mode and ... have never been able to reproduce the...

I haven't given up yet. And I did find out something: So the default (group) rate for an IB subnet (at least as provided on my SX6036) seems to be 10gbps (that's what the ipdiagnet output suggests but I also found some link to corroborate where it said that the default setting of "3" for the...

Great find! I'm going to try that as well.

I have two potential explanations for the low throughout of my 40/56gbps IPoIB: - There might be a bottleneck in the PCIe slots that my IB cards sit in (I have relatively small servers with only few PCI lanes and the available slots may have too few lanes to fully saturate the connections) -...
