Hi Anthony and Serkan, I checked the drive temperatures and there is nothing special about this slot. The disks in this slot are from different vendors and were not populated incrementally. It might be a very weird coincidence. I seem to have an OSD developing this problem in another slot on a different host now. Let's see what happens in the future. No reason to turn superstitious :) Best regards, ================= Frank Schilder AIT Risø Campus Bygning 109, rum S14 _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
