Thanks for the answer. Can you give an example of what the filter should look like if on the main PBS I need to pick up only the last 3 copies of VM`s with ID 6000-6007

Hi all. I have the following question. There are 2 PBS One with a large amount of storage where backups are made from different Proxmox VE nodes, and the second with a small amount of storage. Is it possible to pick up certain virtual machine backups in the amount of 3 from PBS with large...

For example? How to use standard nvme or ssd for persistent cache?

I answer my own question. I have nvme which I wanted to cache - doesn't support DAX.

I would like to try using ssd as rbd persistent cache CEPH device. But it didn't work for me because I can't specify the DAX mount option. Is this functionality missing in PVE or am I doing something wrong?

I understand. Thanks for the tip. I just don’t understand the usage scenario itself yet) I watched the video, read HELP - the essence is not entirely clear.

Greetings. Can I completely disable SDN in a Proxmox VE 8 cluster. I don't plan to use it. If there is no way to remove it, how can I hide the SDN settings from the interface?

ceph version 17.2.6 (995dec2cdae920da21db2d455e55efbc339bde24) quincy (stable) I tested cluster performance with wal/db hosted on nvme and cleared osd several times. The last time I added them, the counters did not appear. + I rolled back to the configuration version "0" with the ceph config...

I have been configuring and testing ceph. When OSDs were first added, the performance values of the added osds were automatically added to the configuration database. However, at some point it stopped working. Should it work? Maybe some update came that turned off this functionality? Running...

Can you clarify how the process of writing and reading on the OSD. From the official documentation, you can see the logic that exactly 1 OSD is used and not a group of OSD disks. That is, in fact, it writes to a specific OSD and then replicates to another OSD 2 nodes and also replicates to OSD 3...

No. I forced the nvme class

ip link set bond0 mtu 9000 Command solves the problem by increasing the MTU. But as far as I know this is not a solution. :eek:

The scenario is quite simple - using your internal services with fault tolerance. Still, I don't understand one thing. When I used nvme to run a data pool on it, the network exchange rate also did not exceed 1.5 Gbit/s as well as with conventional HDDs. Why?

A situation has arisen. Set to MTU 9000 via the web interface. Used by OVS. After restarting the server, the MTU on some interfaces drops to 1500 - bond and ovs-system. How can I fix this? proxmox-ve: 7.4-1 (running kernel: 5.15.107-2-pve) pve-manager: 7.4-3 (running version: 7.4-3/9002ab8a)...
