Hello everyone, I have Asrock 970Pro3 paired with Phenom II x2 555BE unlocked to Phenom II x4 B55 and 24GB RAM (my Proxmox homelab). I have some weird problem and I can't figure out where is the problem. MB doesn't save the UEFI settings for the CPU like frequency or voltage in stock or in unlocked 4 core mode. I tried to change the CMOS battery with new one and no success. Also tried to manually set the frequency and voltage settings but after reboot everything is stock, tried to re-flash the UEFI with the same version or with the older one but still no success. There are some weird things also noticed when tried to clear CMOS not every time is cleared, doesn't boot with 1 RAM stick on the 3rd slot (tried with all 4 that I have and randomly boots) and when CPU is unlocked the Asrock boot guard tells me that the system failed to boot 3 times and the UEFI settings are back to stock also happens in stock non unlocked CPU but not so frequently. The last weird thing that I noticed that even all of the 4 RAM slots are populated (correctly for dual channel) UEFI shows single channel mode. At the moment I don't have other CPU to check if the MB is the problem but the whole setup was working for about 3-4 years without any problems. Can someone help me a bit will be grateful. Thanks in advance.

Hello, I accidentally erased my files from my MDADM raid when I created a Docker container and mapped my raid but after that all files in the raid disappeared. The discs are not currently being written or read. I want to ask what is the way I can recover my files? Unfortunately I don't have a backup. Also I am open to any suggestions even to attach disks to Windows machine. This is my Docker compose config file which I used --> https://pastebin.com/PqwEkZ4G My setup: OS: Ubuntu server 20.04LTS 2xHDD 1TB in MDADM RAID1 + 1xSSD 500GB OS drive FS type: ext4 not encrypted Thanks in advance.

My Ubuntu server is 192.168.1.29, my Lubuntu VM is 192.168.1.7 and my laptop from which im trying to connect to VM is 192.168.1.241.

Yes the server on which is hosted Lubuntu VM is in the same network as the pc from which i am trying to connect to the VM.

Is there a way to access the VM with the ip of the VM from WAN only with any VNC client ?

I have Ubuntu Server 18.04 LTS with some Samba shares, Nextcloud and other services but i want to create a VM with KVM which I can access it outside LAN. I have basic KVM knowledge and at the moment I only can create VM and connect via SSH tunneling and this is the problem because I need to connect outside the LAN. I read a few things in Google that I need to create bridge to connect to VM's outside the LAN. I created bridge then I installed Lubuntu and from the VM I have access to the internet also I checked DHCP list from my router and I can see the VM name and the IP but I can't connect with VNC to the VM without SSH tunneling. Can someone help me to figure out what I am doing wrong? I can give you whatever logs you want to fix the problem. Thanks in advance.
