Sorry. I know this is over 2 years old but i found a solution. See my post here --> https://forums.unraid.net/topic/180247-yottamaster-4-bay-type-c-hard-drive-enclosure-with-unraid/#comment-1488990

Just so you are aware. I had an issue with the Yottamaster 4 bay usb storage device (Yottamaster VN400C3 4 Bay Hard Drive Enclosure) after upgrading to Unraid v7.x. It was working on 6.x but would have a weird issue on random reboots that would swap serials or order and i would have to reboot again to resolve. But anyway. By adding in usb_storage.quirks=2109:0715:u to my syslinux config under Main, it was able to detect the correct serial numbers and my array came online. You can get your Vendor and product id from running a lsusb -v from the terminal and looking for something like this Bus 002 Device 006: ID 2109:0715 VIA Labs, Inc. VL817 SATA Adaptor Hope this helps others. PS. i dont have a parity disk. and use a M2 Nvme Cache disk for extra speed.
