Hi Eugen,

I have delected osd.3 directory from datastorn4 node as you mentioned but
still i am seeing that duplicate osd in ps output.

root@datastorn1:~# ceph orch ps | grep osd.3
osd.3                      datastorn4                stopped          5m
ago   3w        -    42.6G  <unknown>  <unknown>     <unknown>
osd.3                      datastorn5                running (3w)     5m
ago   3w    2587M    42.6G  17.2.3     0912465dcea5  d139f8a1234b

How do I clean up permanently?
