The large OSD number (-1 for a signed 32bit int) just means the cluster has no info about the OSD that held this part, so it is ceph's way to say "unknown OSD". As to why you see it in a normal running cluster without long running outages I don't know. I would "ceph pg dump" one of the affected PGs until you see how the OSD list looks with and without this rogue OSD so see which OSD is acting up. The list is the numbers inside []s, so when [73,12,45,33] turns into [72,2147483647,45,33] you know that OSD.12 is doing something fishy. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
