> The OSD daemon would crash I would assume. Since I don't understand why the OSDs should crash just because a disk goes into standby, I just tried it now. The result is very unspectacular und fits perfectly to Gregorys great explanation. The drive goes into standby for around 2 or 3 seconds and spines up again. The OSD daemon doesn't seem to care at all about the spin down. @Gregorys: Thank you for you explanation.
