Techniques coordinate deduplication among nodes. The techniques involve, in response to a lookup query to search a deduplication index for an entry that maps a fingerprint which is based on incoming data, detecting an invalid result. The techniques further involve, in response to detecting the invalid result, updating the deduplication index to include an entry that maps the fingerprint, the entry initially storing an 'in-progress' flag. The techniques further involve, after the deduplication index is updated to include the entry that maps the fingerprint and after the incoming data is stored in a storage location, removing the “in-progress” flag from the entry.
