You can reduce the mdadm.conf to just use UUID and nothing else ARRAY /dev/md0 UUID=cb850648:d5b35007:dc6000f0:b48ab578 Keep the /dev/md/name if you need it but everything else (num-devices, metadata, devices, level, ...) is part of the metadata, no need to duplicate it in the conf. There doesn't seem to be a problem with the metadata itself (all clean, same update time, same event count) so unless the devices get detected late or something it should just work when assembling by UUID...
