Have two WD 4TB NAS drives
Have two USB 3.0 powered adapter trays.
Have Raspberry PI 4 running OMV (5.3.2-1)
OMV only seeing one of the 4TB NAS drives (sdb) on the USB 3.0 ports.
Again newbie so my apologies but I see apparently I can NOT use RAID 1 (or any RAID for that matter) with a USB interface. True under all circumstances?
Is there a workaround for my lovely WD NAS HDD's as storage devices?
If no, any suggestion on getting an 'almost' RAID 1' setup (maybe with some regular automatic or manual maintenance copying data from hdd1 to hdd2?
Help me obi wan... you're my only hope
