Hello, in afr.c i can read : afr_first_up_child function which is always call, but if i understand, there's no load balancing in afr, just the first child up is taken. Can I just implement a Round Robin function to alternate between child up or it's more complicated ? Regards, Nicolas Prochazka /* first_up_child - return the index of the first child that is up / int afr_first_up_child (afr_private_t *priv) { xlator_t * children = NULL; int ret = -1; int i = 0; LOCK (&priv->lock); { children = priv->children; for (i = 0; i < priv->child_count; i++) { if (priv->child_up[i]) { ret = i; break; } } } UNLOCK (&priv->lock); return ret; }
