It's not a nightmare. It's just not possible. You can sleep soundly. :) > As far as I was told, linbit is working on three-way drbd-replication on a single-layer. But there are other systems both on the block- and on the fs-layer that do n-way replication... Yup. Well actually I'm not aware of anything that does n-way multi-master at the block level, although you could say that RBD does (not exactly correct, but close enough). Multi-master n-way filesystem replication is available in GlusterFS. Florian -- Need help with High Availability? http://www.hastexo.com/now
