Hi, after many VM crashes during upgrades of Gluster, losing network connectivity on one node etc. I would advise running replica 2 with arbiter. I once even managed to break this setup (with arbiter) due to network partitioning - one data node never healed and I had to restore from backups (it was easier and kind of non-production). Be extremely careful and plan for failure. -ps On Mon, Aug 21, 2017 at 10:09 PM, Gionatan Danti <g.danti@xxxxxxxxxx> wrote: > Hi all, > I would like to ask if, and with how much success, you are using GlusterFS > for virtual machine storage. > > My plan: I want to setup a 2-node cluster, where VM runs on the nodes > themselves and can be live-migrated on demand. > > I have some questions: > - do you use GlusterFS for similar setup? > - if so, how do you feel about it? > - if a node crashes/reboots, how the system re-syncs?
