Hi all,
    
I am testing luminouse for ec pool backed rbd[k=8,m=2].   My luminouse version is: ceph version 12.2.1-249-g42172a4 (42172a443183ffe6b36e85770e53fe678db293bf) luminous (stable)
My cluster had some osd memory oom problem so some osds got oom killed.The cluster entered recovery state.During the recovery I found some log like blow:

2017-11-04 12:12:11.041217 osd.7 [ERR] Error -2 reading object 4:4c277622:::rbd_data.3.390e74b0dc51.0000000000186276:head

     I haven't seen this error before and I can't google any infomation about it either.
     What could cause this error?Is there a way to fix it?
