The mismatch only becomes important during rebalance. Prior to that, even if we've added or removed a brick, the layouts haven't changed and the optimization is still as valid as it was before. If there are multiple add/remove operations, we don't need or want to change the hash between them. Conversely, there are cases besides add/remove brick where we might want to do a rebalance - e.g. after replace-brick with a brick of a different size, or to change between total-space vs. free-space weighting. Changing the hash in add/remove brick doesn't handle these cases, but changing it at the start of rebalance does. _______________________________________________ Gluster-users mailing list [email protected] http://lists.gluster.org/mailman/listinfo/gluster-users
