[ceph-users] how io works when backfill

2015-12-27 Thread Dong Wu
Hi, When add osd or remove osd, ceph will backfill to rebalance data. eg: - pg1.0[1, 2, 3] - add an osd(eg. osd.7) - ceph start backfill, then pg1.0 osd set changes to [1, 2, 7] - if [a, b, c, d, e] are objects needing to backfill to osd.7 and now object a is backfilling - when a write io hits

Hi, I have doubt about pglog, the pglog contains (op,object,version) etc. when peering, use pglog to construct missing list,then recover the whole object in missing list even if different data among replicas is less then a whole object data(eg,4MB). why not add (offset,len) to pglog? If so, the mis
