Ok so I guess I did not set up the raid management software when I installed my raid. A hard drive died but I had a drive sitting there to expand the raid. I installed the new drive and the rebuild started. Of course the load on the drives when rebuilding is super hard and 2 more drives failed. I have a back up, but it’s 3 weeks back and will take some time to get everything back. But I will be using the back up for some time since 2 more drives is a bit of money.
