The rage ship is unaccounted. There is no mention of it being destroyed or abandoned. Also Bloodlines can restart a clan again.
The Rage was captured by the Coyotes. This is explicitly mentioned in Wars of Reaving page 112. When the Adders make their first attempt to go to Tamaron in 3072 and discover the Rage among the Coyote fleet defending the system, and are defeated by them. The Rage gets specifically called out for "Crossing the T" of the Adder warship Eagle and crushing her nose. But then the Eagle goes haywire and flies out of control. Then it's noted that the Rage transmitted some kind of localized HPG burst to the Eagle.
We don't hear of the Rage again, but we know the naval battle over Tameron in 3074 (WoR page 143) left a lot of destroyed ships. When the Vipers jumped in with all of their fleet they found the Tameron system SDS and 2 full naval stars defending Tameron. We don't know the names of all the warships involved but since the Rage was part of the defense of Tameron in 3072, it makes sense that she would be there again as one of those 10-12 warships (2 stars) in 3074.
The Vipers Leviathan Prime is said to have left a "string of broken hulls" behind it as the Viper fleet approached the planet. Until the Texas-class Ancestral Home takes out the Leviathan Prime by initiating a jump that destroys both ships.
It's said that the naval battle continued for a week after the ground assault on Tamaron started. It specifically names one Coyote warship surrendering while two others jump away to link up with the Coyotes at Kirin. (all these warships are specifically named).
That means out of "2 complete naval stars", so 10-12 warships total, 7-9 were destroyed. We aren't given the names of those vessels.
Whether its prior to that assault on Tameron (as part of the Coyote/Society operations across the Homeworlds) or whether (to my mind, more likely) the Rage died in the assault on Tameron, possibly as one of the 7-9 warships taken out by the Vipers in the assault on Tameron, what we know for sure is that the Rage became a Clan Coyote ship.
EDIT: If a missing Mandrill ship is what you are looking for, a better bet would be the CFM Firetender of Kindraa Faraday-Tanaga. No references to her at all in WoR. Though Faraday-Tanaga got stuck on Atreus under attack by the Streaking Mist and then later shattered by a plague, and then the survivors were absorbed into the Blood Spirits. She probably died trying to support the Kindraa on Atreus, or as part of the Blood Spirit fleet in the Viper annihilation. But that's pure speculation and it certainly leaves room for the idea that something else happened to her.
Two other missing ones are the Firehold and Reaver. Kindraa Payne-Beyl-Grant's ground forces died on Arcadia trying to launch a Reaving Trial against the Ghost Bears, but it isn't stated what happened to their fleet (except the CFM Anathema, which was discovered in complete shutdown in the Marshall system later by the Stone Lions). Right after that the Bears left the Homeworlds. Could be fun if one or both was scooped up by the Bears in the process or otherwise went off on some adventure we haven't heard about.
