Solved after replace 1TB Crucial P5 NVME SSD with a Samsung 970 Evo Plus 1TB. However, same Crucial P5 in same computers, works fine with Ubuntu 21.04. I think something is wrong with UnRAID 6.9.2 kernel I found another post about same problem with another NVME:

I just installed a 2TB Crucial P5 NVME SSD and lose access to the disk when UNRAID reads SMART data (when accessing from the web by clicking on the disk). I know that the problem is when reading the SMART information, because I reproduce the same error when I do it from the console with smartctl.
