Go for it. Having the two bricks knowing about each other must make sense. It could also make reconstruction a lot quicker if the working brick knew that the failed brick was working until time T then when the failed brick comes up it's probably safe to say that files with an mtime less than T-120 were OK. And maybe in the long term the client-side stat buffer could be updated via multicast.. On the other hand, when the master brick goes down it will be tricky to make sure that the effective file-system is unchanged with the switchover to the former slave. Several ways to think of doing that but the devil is in the details. John
