I'm running AOS 5.1 with ESXi 6.0 and trying to setup a new Metro PD. I've created a container with that same name on both clusters and mounted to all ESXi hosts. Now when I go to create the Metro PD, the Remote Site shows 'incompatible' because the 'Storage container has existing data'. When I look, the only data that I see in this datastore is a folder called ".iorm.sf" that has a single 1 kb file named "slotsfile".
I suspect that this is related to vSphere's Storage I/O Control being Enabled but it's showing NOT enabled in the hypervisor. Nevertheless, when I deleted the file & folder from within the datastore browser, it immediately returns.
Has anyone else encountered this and/or know what the solution is?
