I don't really use the HA features of proxmox that often, mostly just for migrating vms across hosts. But I had been thinking of re-installing some of my remote servers with proxmox and hooking them up to the same cluster so that I could potentially shut off all of the servers in my basement and run everything from a remote location, then migrate the vms back later.
- j45 3y agoOP may know better, but in part it may depend on the ms latency between the sites?
- alias_neo 3y agoI've not noticed anything latency-sensitivty, perhaps the Ceph feature? I'm not using that though. There's also the issue of quorum of it's only a 2-node cluster, though I've personally not had any issues with it, despite repeatedly restarting the different nodes. I see no reason why you couldn't do this to allow you to move your VMs from home to elsewhere and back again as you just mentioned.
- johntash 3y agoceph is latency sensitive, but that should only matter for the servers running ceph and not (as much) the clients using it. I thought quorum feature of proxmox was also latency sensitive, but this is the only thing I found: https://pve.proxmox.com/wiki/Cluster_Manager#pvecm_cluster_network_requirements https://pve.proxmox.com/wiki/Cluster_Manager#pvecm_cluster_n... Maybe this doesn't matter if not using HA? I'll read more about it and maybe test it out
- alias_neo 3y agoYeah I've not had any issues. I have nodes they are offline for months when not in use, it doesn't seem to have any effect of you're not using HA. Just my experience though, YMMV.
