Hi,
I target to run just destroy and re-use the ID as stated in manual but seems not working.
Seems I’m unable to re-use the ID ?
Thanks.

Hi,
Yes, I run the commands before:
# ceph osd crush remove osd.71
device 'osd.71' does not appear in the crush map
# ceph auth del osd.71
entity osd.71 does not exist
which is probably the reason why you couldn't recycle the OSD ID.
Either run just destroy and re-use the ID or run purge and not re-use the ID.
Manually deleting auth and crush entries is no longer needed since purge was introduced.

Hi,
did you also remove that OSD from crush and also from auth before recreating it?
ceph osd crush remove osd.71
ceph auth del osd.71
