Great update! That "iSCSI blocking on non-synchronized replica" note from Boris is absolutely gold. It totally explains the 'Service Unavailable' error and is a massive takeaway for anyone troubleshooting HA setups here. I'm definitely saving this thread! Seeing the back-and-forth on shari...

Hey - that’s a good question. If you’re doing “tape redirection” via StarWind Tape Redirector on a VM inside VMware, you want to make sure the redirector is installed on the physical host (where the tape drive is attached), and the iSCSI initiator is running inside the VM.

I searched on every forum on internet and eventually end up fixing this by setting up S2D with two totally separate pools on a single 4-node cluster sounds pretty tricky to manage—Microsoft usually prefers a single pool across all nodes for that architecture. Are you running into trouble with resili...

Hey, I can't see the full thread, but if you're hitting a wall on the VSAN setup or performance tuning, make sure you've ruled out the networking layer first. Nine times out of ten, it’s a subtle MTU size mismatch or a NIC offload setting causing headaches!

One thing to watch out for: make sure you’re not using the deprecated StarWind Hardware VSS Provider for devices that don’t support snapshots — it’s not really supported for non-snapshot storage. Also, check StarWind’s logs (look in C:\Program Files\StarWind Software\...
