In the Halo Graphic Novel story The Last Voyage of the Infinite Succor an Elite of Commander rank boards the Infinite Succor as part of a team sent to recapture the ship after a, presumed to be human, force attacks it. The Commander encounters a Prophet (The Minister of Etiology) who has been observing the attackers and informs the Elite Commander it is a Flood infection (the Commander was previously unaware of what his team were being attacked by, even after establishing it wasn't humans) and that they were "building" a "creature" that he believed "serves as their leader and organizer" (a Gravemind). While escaping the ship the Commander is attacked by an infected Elite armed with two Energy Swords, a duel commences and on the right-hand side of panel four on page fifty-three the Commander has half of his jaw cut off by the Flood Elite. The half-jawed Commander leaves the Infinite Succor as a two minutes to slipspace jump warning is sounded in the second last panel and the story ends with the Commander's Phantom leaving the Inifinite Succor which is intact in the background. The Commander had previously explained to the Prophet it would take fifteen minutes to arrange the Covenant fleet to fire on the Infinite Succor, so it's entirely possible the ship escaped. Though the "Last Voyage" element of the title suggests otherwise*. The story takes place while the Chief is on his way to find the missing Captain Keyes and his team of Marines.
So not only have the Covenant enountered Graveminds in the past, but Half-Jaw himself saw one in the earlier stages of construction and barely escaped. I'd imagine someone would have brought this up in the forums nearer the time but I thought I'd make sure.
*You can elaborate on this by saying that once the ship was completely taken under Flood control it ceased to be the Covenant ship Infinite Succor, in which case the title would fit should the ship have escaped.
Seems that slipped off our minds. We need some logic from time to time. ;)
