This seems pretty cool in principle, but I got as far as a single nonreplicated MDS before I lost interest in trying it out at this stage.
Admittedly, my background is in HPC where metadata performance and reliability requirements would preclude using something like this. Does anyone who is a more familiar with FreeBSD than I am (which is pretty much anyone who’s used it in the last 10 years) have any more information on long their term plans for at least replicated block storage failover or cache coherency in an active/active MDS setup?
