<div dir="ltr">Hi<div><br></div><div>We are running an (admittedly old) rabbitmq cluster pair, both running <span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center">2.7.1 / R14B04</span></div>
<div><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center"><br></span></div><div style><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center">Our NOC recently did some recabling which involved replacing the network cables on both rabbitmq boxes. During this recabling, it looks like both boxes lost network connectivity for a short period (or eth1 became eth0 and vice versa) which caused rabbitmq on both boxes to crash.</span></div>
<div style><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center"><br></span></div><div style><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center">However, upon restart they came back with the vast majority of queues/exchanges and vhosts missing missing, to what looks like a very very old set of 'definitions' </span></div>

Both nodes in the cluster are disk nodes so I would have thought the definitions would be stored on disk to be read in in the event of a restart.</span></div>
<div style><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center"><br></span></div><div style><span style="color:rgb(72,72,72);font-family:Verdana,sans-serif;font-size:12px;line-height:17px;text-align:center">Is it possible it lost the definitions (because both cluster nodes crashed at the same time) so it just loaded in the last one which was imported via the management GUI?</span></div>
