Hello,
I have 3 node, with 3 OSD in each node. I'm using .rgw.buckets pool with 3 replica. One of my HDD (osd.0) has just bad sectors, when I try to read an object from OSD direct, I get Input/output errror. dmesg:[1214525.670065] mpt2sas0: log_info(0x31080000): originator(PL), code(0x08), sub_code(0x0000)

Fragment of ceph -s output:

ceph pg map 11.15d
osdmap e1600 pg 11.15d (11.15d) -> up [0,8,3] acting [0,8,3]
osdmap e1600 pg 11.15d (11.15d) -> up [0,8,3] acting [0,8,3]
pg repair or deep-scrub can not fix this issue. But if I understand correctly, osd has to known it can not retrieve object from osd.0 and need to be replicate an another osd because there is no 3 working replicas now.
Thank you,
Mihaly
