I'd stick with what you have. So far, I haven't found a single version that hasn't had at least one major issue, you'll just need to decide what you can live with.
I'm finding that in the latest version of V8, when using HA, even with the workaround indicated in a previous post, latency can become unbearable on some LUNs. I went ahead and disabled HA on one of my targets and it crashed the service on my partner Starwind server. When I say unbearable, I'm talking latencies in the 30000ms range, even worse than my previous graphs.
In my opinion, HA is still not bulletproof as I've been able to crash the service on at least one of my partner nodes performing a basic operation within the confines of the product. Interestingly, when I test HA by cold booting an HA member, HA works as expected and is pretty reliable. In my latest case, I just removed a replica for an HA target using the UI, and the service crashed. Starwind VSAN is promising, but the basic features need to be bullet-proof. This is meant to be used in production. All of the other features are irrelevant if the basics don't work reliably.
There needs to be transparency when bugs are discovered and this info needs to be communicated to the community in some fashion. I've requested that a post with known issues be populated and maintained to help make our decisions easier as to whether to upgrade to a certain version, but this still hasn't happened yet. We need to know what features are production ready vs ones that are still considered beta.
I hope that Starwind begins to take this aspect more seriously as patience only goes so far.
