Hello all, Thanks for the help. I believe we traced this down to be an issue with the crush rules. It seems somehow osd_crush_chooseleaf_type = 0 got placed into our configuration. This caused ceph osd crush rule dump to include this line ' "op": "choose_firstn",' instead of 'chooseleaf_firstn'. Which I believe would tell ceph to make its failure domain an OSD instead of a node. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
