I have somewhat of an emergency on my hands, and am hoping the community may have some insight. One of the primary fiber rings on my campus will be down for a week, unless the damaged fiber fails, it will be down then. During this time my primary datacenter could possibly have intermittent connectivity to other buildings / outside work. Unfortunately we do not have the resources for a remote data center (yet), but for now I'm setting up a remote KVM server in a portion of campus that will not be effected. Currently all VMs are QCOW2 images that live on a 1.2TB Logical volume. This seems like the perfect situation to use DRBD in active-passive. However I'm not currently trying to prepare for hardware failure but network failure. Is it possible to do this, to have the two LVMs synced with DRBD and then have a resource manager (Pacemaker) detect that the two can't communicate (network failure) and then activate the passive node? I want to avoid as much complexity as possible, so no live migration or dual primary if possible.<div>
<br></div><div>This is really a temporary solution for 1 week for all my organization's web servers, but it has made our executives aware of our need for more funds and a remote datacenter. So hopefully this won't be last I can use DRBD, but I have to do this in the next 2 days.</div>
