Thanks, that was my conclusion as well. As a next step, I will examine the network more closely.
There are plans to expand the cluster by one or two hosts in the near future. Consequently, this is unfortunately not an option.
Thank you for the information about the workaround.
This helped someone else as well already.
Do you remember the exact kernel version?
That would help us narrow down any changes our kernels have, that the Ubuntu one did not.
Since our kernels...
Der Admin hat die Platten der VMs so eingestellt: `cache=writeback, discard=on, iothread=1`
Fragwürdig, oder OK? Sieht für mich eher OK aus.
https://pve.proxmox.com/wiki/Windows_2025_guest_best_practices#Prepare schlägt es auch so vor, meint...
@fabian: no worries. I am glad that we have found the reason for the non-starting LXCs. Even when I still not understand how and why the value has been changed to 3.
@Impact: no files found
I theory I should be able to change the value on...
Leider war's das nicht: beide VMs heute wieder mit Problemen, höre ich gerade vom Kunden.
Sein Admin, der die VMs gebaut hat, ist noch in Urlaub, ich kann ihm zwar vielleicht VMs neu installieren, aber nicht seine Software darin deployen.
Ich...
Hi @Bishop27
thanks for posting in the forum!
So the EFI messages were just a warning for the soon expiring Secure Boot CAs from Microsoft, which you successfully updated as it seems.
The second error message as it says, has something to do...
So now I do understand you. The non-default kernel.yama.ptrace_scope = 3 might cause the issues. Now we need to understand why it is not set to 1 which I assume should be the default. At least I see kernel.yama.ptrace_scope = 1 on my home-lab...
Hi,
1. the script check if reboot is required. You can also set "reboot if nessesary" in config file.
If the option is not set, and welcome screen is installed, you become notification after login, if a VM need reboot.
2. There is no HA...
As far as I know the only changes that have been made can be found in /etc/modprobe.de:
One is dirty-frag.conf
install esp4 /bin/false
install esp6 /bin/false
install rxrpc /bin/false
And for copy-fail called disable-algif.conf
install...
Hello,
We've recently migrated from ESXi to Proxmox. We are using the same storage we used at ESXI EV, it's FC SAN mounted as usual in such case.
We have two disks 15Tb each. We use Proxmox as cluster with multuple nodes, 4 nodes now active...
Thanks for the logs.
So to me it seems like there was a network communication issue where the nodes 1 and 2 couldn't communicate with each other over the Ceph interfaces. Corosync seems fine according to the log.
My reason to believe this: Log of...
Ok, got it.
I can access the Ceph RBD directly through qemu-img. Great!
- Shrink partition inside the VM (Windows, gparted, etc.)
- Shutdown VM
- Resize the image: qemu-img resize -f raw --shrink rbd:<pool>/<disk-img> <size> (example: qemu-img...
Hm,
not sure if this setting has been touched. Here is the wanted output:
root@proxmox-2:~# sysctl kernel.yama.ptrace_scope
kernel.yama.ptrace_scope = 3
Ive created a subnet (10.10.10.0/24, gw. 10.10.10.1) for Vnet wan1. After applying I cannot find an ip address
assigned to the bridge.
I was search in /etc/network recursivley.
Maybe there is another routing table or namespace where the ip is...
Thanks Daniel for providing the correct command syntax.
Here is the correct output from journalctl that does contain the failed start of LXC. Just the clearify: it is not only this container that fails. I see all containers not working on our 3...
Separate DKIM keys for each domain are a must-have for security, as they prevent email spoofing and ensure that each domain's emails are cryptographically verified independently, reducing the risk of a single compromised key affecting multiple...
