Siyao Meng commented on HDDS-9930:
----------------------------------
Thanks [~pratyush.bhatt] for the observation. So it looks like we just need to
prevent the client from successfully hsync()'ing again when the key/file is
already deleted. Possibly just by checking and *removing the key from
{{OpenKeyTable}} as well during key deletion* in
{{OMKey(s)DeleteRequest(WithFSO)}}? Would there be any concern for lease
recovery? [~Sammi]
