Hi, everyone. Recently, one of our online cluster experienced a whole cluster power outage, and after the power recovered, many osd started to log the following error: 2021-04-27 15:38:05.503 2b372b957700 -1 bluestore(/var/lib/ceph/osd/ceph-3) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x36000, got 0x41fe1397, expected 0x8d7f5975, device location [0xa7e76000~1000], logical extent 0x1b6000~1000, object #9:45a4e02a:::rbd_data.3b35df93038d.0000000000000095:head# 2021-04-27 15:38:05.504 2b372b957700 -1 bluestore(/var/lib/ceph/osd/ceph-3) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x36000, got 0x41fe1397, expected 0x8d7f5975, device location [0xa7e76000~1000], logical extent 0x1b6000~1000, object #9:45a4e02a:::rbd_data.3b35df93038d.0000000000000095:head# 2021-04-27 15:38:05.505 2b372b957700 -1 bluestore(/var/lib/ceph/osd/ceph-3) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x36000, got 0x41fe1397, expected 0x8d7f5975, device location [0xa7e76000~1000], logical extent 0x1b6000~1000, object #9:45a4e02a:::rbd_data.3b35df93038d.0000000000000095:head# 2021-04-27 15:38:05.506 2b372b957700 -1 bluestore(/var/lib/ceph/osd/ceph-3) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x36000, got 0x41fe1397, expected 0x8d7f5975, device location [0xa7e76000~1000], logical extent 0x1b6000~1000, object #9:45a4e02a:::rbd_data.3b35df93038d.0000000000000095:head# 2021-04-27 15:38:28.379 2b372c158700 -1 bluestore(/var/lib/ceph/osd/ceph-3) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x40000, got 0xce935e16, expected 0x9b502da7, device location [0xa9a80000~1000], logical extent 0x80000~1000, object #9:c2a6d9ae:::rbd_data.3b35df93038d.0000000000000696:head# We are using Nautilus 14.2.10 version, and we put rocksdb on top of SSDs while bluestore data on SATA disks.
