It failed after a repeated series of power interruptions. There are 4 x 1TB drives with 2 RAID 5 arrays spread across them. One array is working (md126) as are all 4 drives. The boot drive was on the failed array so the system is running from a Fedora 33 Live USB. Details of the 3 arrays and 4 drives follow.
