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
Thank you for your reply. I am looking formard to Sage's opinion too @sage.
Also I'll keep on with the BlueStore and Kstore's progress.

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
