Correct me if I'm wrong but I have been left with the impression that cluster heal is multi-process , multi-connection event and would benefit from a bonding like balance-alb. I don't have much experience with xfsdump, but it looks like a single process that uses single connection and thus only LACP can be beneficial. Am I wrong?
