When having software raid solutions, I was also thinking about spinning them down and researching how to do this. I can't exactly remember, but a simple hdparm/sdparm command was not sufficient. Now I am bit curious if you solved this problem with mdadm / software raid? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
