Wild guess based on many past experience with "lost" data/disks. If the partition table moved because of some mistake (someone/something repartitioned the disks and moved the start of the partition) then after the reboot the array would be "missing" as the header is not where it expects it to be. If the array was on unpartitioned disks and the disks later got partitioned that can also hide the disk. Either of these will appear to cause the array to not be found. Or if the disk was partitioned but the partition was remove that will also cause the array to be missing.
