> configure filewall to prevent messages from BSI/Hetzner for open NFS ports I'm not getting warning about open NFS ports but I'm getting a ton of abuse messages about invalid MAC addresses. Can you filter those out? Installing the system was fine. Here is my complete story to help the next...

I am assuming you're using the Grand Wazoo plugin. As some point you added a new volume, and accepted the default of 8192. If you study the screenshot below, you'll see in this screenshot, the default was 4K. This is clearly the wrong default if you want to avoid those warnings. So what I did...

I solved this the hardcore way. I created another iSCSI disk using 16384 pointing to the same disk as the original 8192 volume. I then live migrated my VMs one by one (8192 disk to same disk but 16384) and after many hours I had everyhing in the right size. I then was able to delete 8192 volume...

I want to monitor IO Wait, also called wa in top. I have a script that outputs the values, which works perfectly inside the VM: $ sh check.sh 2024-10-28 06:03:11 - IO Wait: 18%, Load averages: 1.13, 1.15, 1.26 2024-10-28 06:03:13 - IO Wait: 21%, Load averages: 1.20, 1.16, 1.27 2024-10-28...

I just had a situation similar to @linkstat . In fact, I have it quite often when I have failed or aborted migrations between different disks using Proxmox and TrueNAS core. I often have a disk that 'stays behind' although the copy worked. I don't really worry about this these disks, until this...

Hi @whitemeercat68 , Thank you! You reminded me what a great product LibreNMS so I revived an old installation. It turns for now at least LibreNMS perfectly suits my need. As an aside I also use PRTG which has exceptional reporting and push (incessant) notifications. In summary: LibreNMS...

I logged a ticket with Modules Garden support and within minutes the problem was resolved. Honestly these guys have the very best support in the world, worth every cent.

Thank you! After months of struggling with Proxmox Backup Server I find this post which is so helpful to me. What started of as a single installation of TrueNAS Scale about year ago has grown into four different NAS installations spread across a cluster. My original environment was...

After battling to understand this problem and all the terminology in my near perfect Proxmox VE environment, I have finally made substantial progress in solving the issue for (my environment). Environment: - Proxmox VE - ZFS over iSCSI to TrueNAS Scale When you set up ZFS over iSCSI with...

Our network consists mostly of 10 Gbit/s switched backbones to the internet. On the network we have a cluster of Proxmox VM hosts with around a 100 VMs. We have the need to do traffic accounting, per VM, in the most efficient manner. We don't need to count protocol traffic flowing via internet...

Similar problem with PVE 8.2. I'm logging a ticket with Modules Garden now.

My setup is: A Proxmox VE host server with 1000Mb/s physical network card An ZFS over iSCSI link to a virtual machine on the same host which is running TrueNAS Core. Virtio. Numerous VMs all sharing the same NAS, mostly Debian derivatives. All Virtio On the host: # ethtool eth0 Settings for...

I tried this in /etc/snmp/snmpd.conf and it didn't work: dontLogTCPWrappersConnects yes So now I guess we wait for Debian or the Proxmox VE teams to evaluate the latest SNMP service updates, and decide if it's worth including this bugfixed version given the risks, if any.

I have a similar question. 2.7 GB total disk space maxroot made to be 1024 GB during installation. pve-root ends up being 708.4 GB after this new installation. Is there an easy explanation why pve-root is limited in size in proportion to the total disk space? (I read somewhere 1/3 not 1/4).

All the guides you show are relevant. I think your SNMP service is actually working because I see this: Active: active (running) since Tue 2024-03-12 09:46:36 CET; 8min ago With regards to the snmp-mibs-downloader library, it's strictly speaking not needed but installing it will make SNMP...

Have you tried this on 8.1.2?

This screenshot of Proxmox Mail Gateway 8.1 attempts to address the title of this post: How to change postmaster email?

After battling to understand these settings myself, and then carefully reading the Postfix documentation over and over again, I conclude these are both very good settings to enable by default. 1. The first setting, "Reject Unknown Clients", does a more intense PTR check and if there are...

This is how I find it in the log: More specific, you can do this: Then I get this: In the UI I one can see this: The only anomaly I found on a new installation was that `clamav-freshclam` wasn't started: But of course that was quickly sorted out with:

I can't vouch for Hostbill because I've never used it, but I'm an avid user of WHMCS. From the client side, the Modules Gardens WHMCS Proxmox VE module is really great. It's easy to understand, intuitive, and it's high quality software. Also they really keep things up to date - as of today...
