I got it about how many disks I can lose and so on.But regard the arbiter isse, I always set this parameters in the gluster volume, in order to avoid split-brain and I might add that work pretty well to me. I already have a Proxmox VE cluster with 2 nodes and about 50 vms, running different Linux distro - and Windows as well - with Cpanel and other stuff, in production.Anyway here the parameters I had have used: gluster vol set VMS cluster.heal-timeout 5 gluster vol heal VMS enable gluster vol set VMS cluster.quorum-reads false gluster vol set VMS cluster.quorum-count 1 gluster vol set VMS network.ping-timeout 2 gluster vol set VMS cluster.favorite-child-policy mtime gluster vol heal VMS granular-entry-heal enable gluster vol set VMS cluster.data-self-heal-algorithm full gluster vol set VMS features.shard on gluster vol set VMS performance.write-behind off gluster vol set VMS performance.flush-behind off --- Gilberto Nunes Ferreira Em dom., 20 de out. de 2024 às 17:34, Strahil Nikolov <[email protected]> escreveu: If it's replica 2, you can loose up to 1 replica per distribution group.For example, if you have a volume TEST with such setup: server1:/brick1 server2:/brick1 server1:/brick2 server2:/brick2 You can loose any brick of the replica "/brick1" and any brick in the replica "/brick2". So if you loose server1:/brick1 and server2:/brick2 -> no data loss will be experienced. As usual, consider if you can add an arbiter for your volumes.
