Hi Patrick, Please keep replies on the list, it helps keep the conversation in the archives which can help people in the future. :) If you get a "reboot without logging", please tell us exactly what triggered it and what your configuration is. Either it's a misconfiguration or a bug, either of which are good to discover and understand properly. To answer your questions; I use the switches to help with debugging. With back-to-back, if a link drops, both go down. It makes it harder to diagnose where the problem is. Also, with managed switches, you can get tools to test and diagnose links as well. Gluster is really a cloud solution, not really an HA solution, so I don't think it's relevant here (though others may disagree with me). Note as well that I only use active/passive (mode=1) bonds because, in my testing, that is the only method that can reliably survive both failure and recovery and has the fastest fault detection and recovery possible.
