this is happen after some OSD fail and i recreate osd.

i have did  "ceph osd rm osd.4"  to remove the osd.4 and osd.6. but when i
use ceph-deploy to install OSD by
 "ceph-deploy osd --zap-disk --fs-type btrfs create ceph0x-vm:sdb",
ceph-deploy result said new osd is ready,
 but the OSD can not start. said that ceph-disk failure.
 /var/lib/ceph/bootstrap-osd/ceph.keyring and auth:error
 and i have check the ceph.keyring is same as other on live OSD.

 when i run ceph-deploy twice. first it will create osd.4, failed , will
display in osd tree.  then osd.6 same.
 next ceph-deploy osd again, create osd.10, this OSD can start successful.
 but osd.4 osd.6 display down in osd tree.

 when i use ceph osd reweight-by-utilization,  run one time, more pgs
active+remapped. Ceph can not recover itself

 and Crush map tunables already optimize.  do not how to solve it.
