I'm planning for a Proxmox cluster consisting of 3 nodes for compute and 3 different nodes for Ceph with SSD,
And it's important for me to have HA but I'm concerned about possibility of starting an already running VM on different node by HA controller in case of a network issue.
Does proxmox have any mechanism to prevent starting an already running VM on different node? cause this can easily lead to data corruption.
