Hello everyone, I have long set up the migration of machines with policy defined in the "migration" menu. I noticed, although I did not define a priority in the nodes, that this migration takes place only on 2 nodes. I ask any of you if you can give me any answers.

could you include the output of pveversion -v? there was an issue in pve-ha-manager where resource distribution didn't work properly in some edge cases that got fixed recently.

okay, that's already the newest version. could you describe in detail what you are seeing and what you are expecting, and include all the relevant config files/logs? thanks!

Yes Fabian, what I wrote is that I noticed that when I reboot from one of the 3 nodes, the Vms are always migrated to node 4. the cluster consists of 3 nodes, pve, pv3, pve4 - If I reboot from pve4 these are migrated to pve. In short, in short, it seems that pv3 is ignored ....
 
how many resources are there? how many of them are on each node prior to the reboot?
 
could you post the output of ha-manager status?

but in your example it's clearly visible that vm 127 moves from 3 (back?) to 4?

No Fabian I had changed the real situation. However, if I currently move VMs fairly, as I wrote earlier VMs are migrated between pve and pve4. If pve3 restarts the vms almost always migrate to pve4 .
If you want I can move the VMs to Ha as you want to do tests.

it's still really hard to determine what is going on, please provide the following:
- HA config files, /etc/pve/datacenter.cfg
- ha-manager status before node reboot
- journalctl -f -u pve-ha-lrm -u pve-ha-crm of all nodes starting before the reboot
- ha-manager status after node reboot

this is completely expected behaviour - you start off with 3 guests on pve3, 1 each on pve4 and pve, you reboot pve4, the guest will be migrated to the least-used host (pve) and then back again once pve4 comes up again.

First of all thank you, adeso I try to start all the VMs, and I look at the memory load and CPU. Then I'll write to you.
 
note that the distribution is pretty simple (it just looks at number of HA resources IIRC?)
 
the HA manager will not distribute based on load, it just looks at the configured groups/priorities and resources and the number of non-stopped HA resources on each node
