Hello everyone I am currently running a 2 node microsoft windows server 2012 failover cluster and i have a funky issue that is happening ONLY when the physical router connected to the WAN is restarted. a bit more information to help with trouble shooting: 2 nodes (identical in specs/build) are connected to 1 synology NAS where i have created the iscsi luns that are mounted on the 2 nodes via mpio (round robing w/ subset). Every thing runs smoothly until the physical netgear router is rebooted from time to time.
When i reboot the router the virtual disks in the cluster go offline and so do the associated virtual machines. They will only come back online when the router is up and running once again.
Any ideas on what can be causing this ?
