VM

[CandyAndy]

Hi there, I have some questions
The proxmox cluster has three nodes, each node has two network ports, network port 1 is used as the system management port and inter-cluster communication, and network port 2 is used as the business port to communicate with the storage. three nodes use network port 2 to mount two nfs shares at the same time, and the virtual machine's system disk and data disk use these two nfs shares respectively, and the virtual machine's network port uses network port 1. when one node in the cluster has a disconnected network port 2 and cannot access the nfs share, then the virtual machine on this node cannot be used normally and will not be automatically migrated to other normal nodes in the cluster. When one of the nodes in the cluster has port 2 disconnected and cannot access the nfs share, the VMs on this node cannot be used normally and will not be automatically migrated to other normal nodes in the cluster. Is there any configurations that can make the VMs migrate automatically in this situation?

Besides, When a node is manually restarted or manually shut down, the virtual machines on the node are not automatically migrated to other nodes?
thank you

Hi,

I think what you are looking for is our High-Availability (HA) features. These are not enabled by default, you have to explicitly mark a VM as HA-managed.

For more information please consult the documentation: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#chapter_ha_manager

Thank you for your help. Btw,The nfs shared mount does not show the capacity on the GUI interface the same as the storage side capacity, df -h at the command line to see the capacity is correct but the GUI interface is not correct, is there a switch to fix this? Or is it our configuration problem?

Please elaborate (e.g. with screenshots)

Ah, simple base 1024 (2^10) vs. base 1000 (10^3) conversion error. Numbers should match if you use df --si.

That's worked, thank you
