Luis: As others have mentioned, be sure that when you delete an OSD each step is completed successfully: - OSD process is killed - OSD is marked out/down in the CRUSH map - ceph osd crush delete osd.xxx - ceph osd rm osd.xxx - ceph auth del osd.xxx - Also be sure to unmount the /var/lib/ceph mounts. If you can’t yank an old/bad drive immediately, try to either wipe the partition table or change the typecode on the partitions so that Ceph doesn’t try to remount them. Missing these, especially the last, can result in odd behavior. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
