I'm currently configuring two KVM host servers and things are going along pretty well. I'm story KVM images directly to the drbd devices in raw format, and it's working very well with tolerable overhead. One thing I am wondering, however, is whether I can safely switch from primary/secondary mode to dual primary. I know in most cases you're supposed to have a shared cluster file system, but primarily my interest here is in quickly migrating from server to the other. Removing "drbdadm primary"/"drbdadm secondary" would make things a bit easier. As it stands, only one server is going to be accessing the drbd device at a time (firing up two guests with the same MACs, network configs and the like would be pretty ugly all on its own). Or is it simply safer to continue running in primary/secondary mode? -- Aaron Clausen mightymartianca at gmail.com
