Hello.
I have a production 3 node proxmox 4.1 cluster with an external RBD storage. The external RBD has 3 nodes, each one with a ceph monitor. The hostnames are ceph0{1,2,3}.mynetwork.com. The ceph cluster is healthy and everything works fine. My /etc/pve/storage.cfg is this:
I want to safely change the monhost option to use the three monitors. The monitors are ceph0{1,2,3}.mynetwork.com. Every proxmox node has several running VMs with their disks in the RBD storage. Is it safe to directly modify /etc/pve/storage.cfg on a running cluster? Do I need to reboot each one of the three proxmox hosts after the change or take another action?
Thanks
