Can you talk more about this? It sounds to me like maybe you dislike the performance impact of scrubbing, but it's fairly important in terms of data integrity. I don't think we want to permanently disable them. A corruption in the cache pool isn't any less important than in the backing pool — it will eventually get flushed, and it's where all the reads will be handled! -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
