As an Enterprise user of Rancher, we had long discussions with Suse about Longhorn. And we are not using it.

You need a separate storage lan, a seriously beafy one at to use Longhorn. But even 25Gbit was not enough to keep volumes from being corrupted.

When rebuilds take too long, longhorn fails, crashes, hangs, etc, etc.

We will never make the mistake of using Longhorn again.
