Running UNRAID 6.6.7 on a I7-4930K/EVGA X79 Dark setup...mobo has both chipset and MARVELL SATA controllers. Same issue with the MARVELL controller for me when attempted an upgrade from 6.6.7 to 6.7.0 versions (stable)....array stopped, missing disks, start button greyed-out.
Once rolled back from 6.7.0 to 6.6.7 (and rebooted), the array started up, everything was fine, and all plugins and drives were found and were working.
Any ideas for if/when this would be addressed in a future release would be greatly appreciated. While this is only my test/Lab server (I am learning UNRAID, VMs, Docker containers, etc.), I am sure that others running systems with MARVELL SATA controllers are managing data that potentially would be a bit more important (i.e. production) than mine.
Please and Thank You,
Raj
