I love Proxmox's ability to make it super easy to set up a three-node HA cluster with Ceph. I like to use it for my VMs and SQL databases that require a lot of IOPS. This way, if one of the nodes goes down, my SQL DB VM can be quickly redeployed to another node. That way, if one of the nodes...

Hi, Today, I removed a snapshot from a VM (2TB storage )in the Proxmox cluster. Shortly afterward, Ceph started rebalancing, causing all VMs to go down until I halted the removal process and the rebalancing was completed. What might have caused this issue?
