Here is a thought for a simple fix on AFR, if I have say 10 bricks, and say AFR *:2, then use a modulus of the available bricks, so you would still use available bricks. - eg copy set 1 could go to 1,3,5,7,9 and copy set 2 could go to the 2,4,6,8, or 10th listed brick in the subvolume
command.



Sounds like what you are trying to do can be achieved with the current xlators - but doing the afr over unified bricks. Personally i think that the afr doesn't need to do complicated scheduling, when unify can do that for you......


e.g. unify server 1,3,5,7,9 and 2,4,6,8,10 - then afr *:2 over them

Might be slightly not what your after, but you can get more complicated than that if you wish :)


If your after ultra redundancy, just afr them altogether and afr *:10 :)


Hope this helps

Matt.
