Dear, Ceph. I'm wondering how does Ceph isolate bad blocks when EIO occurs. I saw source codes and I found the logic of deep scrub, chunky_scrub() in PG.cc. And I understood the real recovery logic is in submit_push_data() in ReplicatedBackend.cc. It pulled an object from another replica and submit it. But, I couldn't find the logic about isolating bad blocks for preventing future errors. I think EIO error will occur again when Ceph accesses that block block again. Is there any isolation logic for bad blocks? Thank you. 이 메일은 나눔글꼴로 작성되었습니다. 설치하기
