Just to follow up on this - I haven't had a network failure at all since blacklisting those modules. The onboard NIC is now functioning as I'd expect. The Intel team seems to indicate a BIOS problem - but I'm not sure who to relay this to at Intel who would be in that area...

*facepalm* Yes, yes it was... Can you guess what else I was looking up? :P

Just to follow up on this - I haven't had a network failure at all since blacklisting those modules. The onboard NIC is now functioning as I'd expect. The Intel team seems to indicate a BIOS problem - but I'm not sure who to relay this to at Intel who would be in that area... Wrong thread. My...

I've had some correspondence from Intel. Create a blacklist file for the following modules, eg: File: /etc/modprobe.d/intel-blacklist.conf With the following content: blacklist mei_me blacklist mei_hdcp blacklist mei After rebooting with this blackilst in place, I no longer seem to see...

After running for many hours using the Realtek USB3 network adapter, there has not been a single corosync / network failure. I have made contact with Intel and supplied the referred team with a whole heap of configuration / hardware details - as the NUC is a 100% Intel provided product - and...

So, even after the above, I'm still seeing the corosync problems. It still manifests as: Jun 28 12:21:15 mel-pm2 corosync[1008]: [KNET ] link: host: 1 link: 0 is down Jun 28 12:21:15 mel-pm2 corosync[1008]: [KNET ] host: host: 1 (passive) best link: 0 (pri: 1) Jun 28 12:21:15 mel-pm2...

Actually - I think this might be the source of the issue....... On the Intel NUC, I see the following in dmesg when a full hang of the cluster happens: [293502.911056] e1000e 0000:00:1f.6 eno1: Detected Hardware Unit Hang: TDH <fe> TDT...

Hi all, I'm having problems with my 2 node Proxmox cluster. One is a home built PC that runs several VMs, and the other a second hand Intel NUC to play around with Plex and hardware transcoding using Intel Quicksync. I joined these two in a cluster - but have noticed that I get a lot of...

That's fair.

It may well be worthwhile looking at using the same .pem files if the two certificates are supposed to be the same... Makes no sense to get LetsEncrypt to issue a second cert for exactly the same details. Maybe if I could put that on the wishlist somehow ;)

This is the config I have now: It was `pmg-tls.pem` that was set as the self-signed cert. I copied the file across - so at the moment, the Valid Since and Expires are identical. If I do the Order Certificate -> Order SMTP Certificate, then it does look like the renewal worked: I guess...

Hi mate, I already had this set: However the SMTP side still used the Proxmox self-signed certificate. I'm just wondering now that I've done the file copy manually now, if that will mean I won't have to do it again to update the cert in 80-90 days time...

Just to necro-bump this thread..... I'm running PMG 7.1-2 - and even though I have an acme account, and the pmg-api.pem cert is the correct Lets Encrypt cert, the `pmg-tls.pem` file seems to be a self-signed cert. If I copy one to the other so they are BOTH using the Lets Encrypt cert, will...

This is great - thanks! I use a bind RPZ to alias download.proxmox.com to something else - which means it takes effect for everything using that DNS server. It does look like the DNS zones aren't quite there yet though: $ host download.proxmox.com download.proxmox.com is an alias for...

Ah, excellent - thanks :) I would strongly recommend changing the RAID5/6 part to: * RAID levels 5/6 are experimental and are known to cause data corruption. Use at your own risk. Simply as I've been there before when those warnings weren't present, and I'm partly the reason why those warnings...

Can anyone elaborate on what you can use BTRFS for now? I've been using a mirror for BTRFS passed through as two different HDDs to a guest for a long time - so I'm just wondering what the deal would be there? Can you use Directory for KVM VMs and not have LV's for each VM? How are the...

Ah - I hadn't realised that, thanks...

@fabian Any chance we can bump this for Fedora 33 seeing as its released now? In fact, I wonder if there's any reason to have an upper limit at all? Given that unless you keep bumping this max number with every fedora release, it'll break all the time...

For what it's worth - as a diagnostic step, I added a file /etc/sysctl.d/swappiness.conf and added: vm.swappiness = 0 To save a reboot, I also set this from the command line using: sysctl vm.swappiness=0 Will be interesting to see what effect this has...

I just stumbled across this thread hunting for why my new proxmox nodes are using swap when there's ~40Gb of free RAM.... Running the suggestion of 'swapoff -a && swapon -a' did put things back where they were supposed to be.... ie: machine #2: Machine #3: Then looking at RAM usage on both...
