Hello. I configured Nginx according to this instruction. Everything works great. It has become much more convenient. But the following question arose: ngnix is blocking ports 80 and 443 to obtain letsencrypt certificates. In order to regenerate the certificates, I had to manually stop nginx, get...

Ok. Please tell me for what this option on screenshot?

I read the documentation. But in it I did not find whether it was necessary to enable NUMA in the advanced virtual CPU options in the settings of the virtual machine itself.

As far as I understand, when using multiprocessor boards based on Proxmox, you need to use NUMA in virtual machines. Are there any recommendations for enabling NUMA in virtual machines? Perhaps depending on a certain amount of RAM and the number of cores? In what types of machines is it better...

I found where, thanks. And what happens if I then delete the non-cloned original VM, but the one from which the snapshot was made and the clone itself?

If I click on the snapshot, only the options are active: - Take snapshop - Rollback - Remove - Edit Type of storage is lvmthin

Update. I have reconstructed RAID-10 from old drives. I checked the backup created by Proxmox, located on this array, using the zstd -t command and the archive turned out to be intact. Then I copied it again to external media and checked again. The archive on the media was also intact. So the...

Hello. tell me, can I somehow deploy a new virtual machine from the created snapshot? Is there any way to do this? For example, a user deleted a file inside a virtual machine. It is expensive to deploy backup and sometimes it is outdated. But there is a daily snapshot created by cron. In order...

That is, even if I have snapshots taken at the time of the backup, all the data of the virtual machine at the time of the backup will still be included in the backup file. But there can be data discrepancy if the guest agent is not enabled? But is it better to delete all snapshots before backup?

If I understand correctly. We take a snapshot. From this point on, all data begins to be written to it. At the time of the backup, another snapshot is created. From which drive? from the base or from a snapshot that has already been created? If we have 3 snapshots that are a fork from the first...

This is exactly what I will do in the future. In the meantime, I need to somehow pull out the data ...

The disks in the system are new. 1 week in work. Memory type is ECC. Backup doing on local storage not network. Why After create proxmox don`t check archive with key -t -t, --test Test the integrity of compressed files. This option is equivalent to --decompress --stdout except that the...

When creating a backup, Proxmox said that everything is OK, but how can it be damaged? 2020-07-25 03:54:28 INFO: Starting Backup of VM 102 (qemu) 2020-07-25 03:54:28 INFO: status = stopped 2020-07-25 03:54:28 INFO: backup mode: stop 2020-07-25 03:54:28 INFO: ionice priority: 7 2020-07-25...

I read that OVS can run as an application and as a kernel module. If OVS is launched as a kernel module, then the performance is higher. As I understand it, since Proxmox OVS is not enabled by default in the basic installation, but it needs to be installed, does it work as an application? Or I'm...

Can you please tell me how much the bandwidth drops when switching from the classic network design in Proxmox to openvswitch?

I made a backup of the virtual machine before replacing the hard drives. Copied it to USB. There were no problems. The size of the copied file was the same as the size of the created one. The virtual machine was turned off at the time of backup. When trying to restore a machine from a backup, I...

Hello. The following question arose. For example, I have a snapshot of the system every day at 21.00 from Monday to Friday. On Saturday at 00.30, backup starts by creating a snapshot. What exactly will be included in the backup file? The state of the VM before the last snapshot was taken, namely...

Hello. As far as is known, rc.local does not work in Debian 10, but even when it is created, and then adding the launch of your code through systemd, an error is generated. Perhaps you have a swap blocking solution in Proxmox 6.2? At first i create /etc/rc.local file with content: #!/bin/sh -e...

Ok. If i correctly understanding Proxmox may direct access to diks. If disks configured as Raid, not HBA - TRIM/Disacard will be not working?
