Hey so I had some issues with my old UNRAID HW TLDR I had some issues with a HBA as well as old HW, so I got some new HW and now I have some problems with the Cache-drive.   I got an upgrade to the hardware, to the following: CPU – Ryzen 5 3600 MB - MSI x470 Gaming Plus RAM – Crucial Ballistix 32GB HBA - LSI 9211-8i + my old NVME from previous system – Crucial Force MP510 1TB This was also the cache-drive in my "old" Unraid server.
