What would be the best approach to integrate SMART with ceph, for the
predictive failure case?
Assuming you agree with SMART diagnosis of an impending failure, would it be
better to automatically start migrating data off the OSD (reduce the weight to
0?), or to just prompt the user to replace t

Currently (as you know) we don't do anything with SMART. It is obviously
important for the entire system, but I'm unsure whether it should be

T failures can be dangerous if
they are not bad enough to completely tear down an OSD therefore it will
not flap and will not be marked as down in time, but cluster performance
is greatly affected in this case. I don`t think that the SMART
monitoring task is somehow related to Ceph because seper
