August 8, 20214 yr I have been a long time user of unraid but my most recent hardware upgrade didn't go as planned. I have 4 disks plus a cache disk. I had the 4 data disks in a USB enclosure, and the cache on sata. In the new system it has a sas bay. I moved the 4 drives into the sas bay and booted up. The system comes online but the drives all have new uuids. I know I can put them in the USB get it online and then one by one put them in the sas and then parity check, but I really don't want to do that. Is there anyway to force the drives online since it's the same drives all with good data.
August 8, 20214 yr Community Expert One of many reasons USB isn't recommended for array or pool disks. Tools - New Config will let you assign any disks as you wish and (optionally, by default) rebuild parity. Check the box saying parity is valid before starting the array then see what you have, hopefully USB won't have made those disk partitions or anything else not work correctly.
