currently on 6.2.4, its only showing 6.3.2 as the latest update (even after telling it to update plugins)

using the manual plugin update method as noted in the first post.. installing 6.3.3 now... noticed after it booted (havent started array) I see a group of log entries every 30 secs of the inventory list (list of the hd found + key info + slot info)...  this results in about 60? lines each time... this could easily add up to a lot of noise if a user left their server idling.. wonder if its because the webui is open causing it? started the array and it stopped.


so far nothing blew up going from 6.2.4->6.3.3.

Anyone else having their nvidia driver crash their Win10 VM since hoping onto the 6.3 versions?


As I mentioned in the 6.3.2 announcement thread, I did a full update of all the virtio drivers, machine type, agent, nvidia drivers, and everything perked up quite a bit. But since doing that, I started having an issue where when gaming the VM would crash to a black screen. Then have to force the VM closed via the nRAID gui. I thought maybe the newer nvidia driver might be causing it, and reverted back from 378.92 to 376.19. Instead of a full blown crash though, now it will flash a black screen, audio will stop, and win10 will give an error saying that the nvidia driver crashed. Since it wasn't happening in 6.2.4, I just wanted to see if anyone having this issue. I've got some even older nvidia drivers that I'll try out and see if that helps resolve the issue. Posting diags, just in case anyone sees something I'm not ^^;

I appear to have lost 10 seconds even though they averaged the same speed between 6.3.2 & 6.3.3...


Back to the drawing board please Limetech!
