Since a couple of days we see random OSDs with a segfault from safe_timer. We didn't update any packages for months. Regards [1] https://tracker.ceph.com/issues/23352 Zitat von Rudenko Aleksandr <arude...@croc.ru<mailto:arude...@croc.ru>>: Hi, guys. After upgrade on Luminous i see: Monitor daemon marked osd.xx down, but it is still running this happens 3-5 times a day on different OSDs. I spent a lot of time on debug but i haven’t found problem. Network works perfectly. CPU, network and disk utilization is low. Memory is enough. Maybe deep-scrub, but we have following config: osd scrub sleep = 0.2 osd scrub chunk min = 1 osd scrub chunk max = 2 and we didn’t see OSD flapping on Hammer and Jewel during scrub. _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
