Subject Re: data deleted came back after 9 days.

Actually, tombstones are read repaired too -- as long as they are not
expired.  But nodetool repair is much less error-prone than relying on
RR and your memory of what deletes you issued.

Either way, you'd need to increase GCGraceSeconds first to make the
tombstones un-expired first.
