Hi List, I read a old article about how ceph client read from ceph cluster.It said the client only read from the primary osd. Since ceph cluster in replicate mode have serveral copys of data only read from one copy seems waste the performance of concurrent read from all the copys. But that artcile is rather old so maybe ceph has imporved to read from all the copys? But I haven't find any info about that. Any info about that would be appreciated. Thanks 2018-01-26
