Disks fail to spin down 3 weeks after upgrade
Perhaps coincidental.. Upgraded a ReadyNas duo v1 to 2 x 1TB Seagate drives (from "approved" list). All seemed fine after couple restarts (file operations, and media streaming fine) for 3 weeks or so...
Further info from system.log. Some process called noflushd seems to be involved:
