I now have several devices that start the monthly mdadm scheduled check. I can let them all run monthly, stagger the checks, or disable them completely. I had the misfortune of several disks turning up bad this month causing a few arrays to run in a degraded state for many hours and I'm not sure what the idea setup is for this. Conversation regarding this topic would be greatly appreciated.
