Hi,
I have two servers running Server 2016 Data Center and I am trying to set up a high-availability fail-over environment using Storage Spaces Direct (S2D) for a bunch of Hyper-V VMs that will be running on the two servers.
I have created the cluster, enabled storage spaces direct, created the S2D storage pool, created two virtual disk from the storage pool (formatted as ReFS) and then created a Volume in each Virtual Disk. There is a file share witness configured on a local
server. Cluster Validation is all passes (except for an unsigned driver for logmein display mirror, and a complaint that one of the servers is on a slightly different version of the windows defender definitions).
On both servers, I can see that I have c:\clusterstorage\volume1\ and c:\custerstorage\volume2\
However, when I shut one of the servers down, the other server looses visibility of one of the c:\custerstorage\volumeX\ folders.
When I have VMs stored in c:\custerstorage\volume1\ and ..\volume2\ and both nodes are up, everything is fine and I can do live migrations between hosts. But when one of the servers is shut down the live migration happens but then when the other server looses sight of one of the c:\custerstorage\volumeX\ folders the VM locks up and stops working (not surprisingly).
It's my first time using S2D so, does this sound correct? I would have thought that even if I take one of the nodes down, the other node should still retain visibility of both its c:\custerstorage\volume1\ and ..\volume2\ folders thanks to the magic of S2D.
Is there any trouble-shooting I can do to figure out why this isn't working?
Possibly relevant: I am building this system in my lab for a client. The client has a single SBS2011 server on their LAN at a different site. I have created a site to site VPN from my lab LAN to the customer's LAN. All NICs on the servers (excluding the 2 x 10 GbE NICs used for SMB/S2D/etc) have their DNS settings pointing to the customer's DC over the site-to-site VPN. The hyper-v hosts are connected to the customer's domain in this way.
