Hi, We've experimented with runing OSD's in docker containers. And got the situation when two OSD's started with the same block device. File locks inside mounted osd dir didn't catch that issue because mounted osd dirs where inside containers. So, we got corrupted osd_superblock at osd bluestore drive. And now OSD can't be started. # /usr/bin/ceph-osd -d --cluster ceph --id 74 2019-01-31 15:12:31.889211 7f6ae7fdee40 -1 bluestore(/var/lib/ceph/osd/ceph-74) _verify_csum bad crc32c/0x1000 checksum at blob offset 0x0, got 0xd4daeff6, expected 0xda9c1ef0, device location [0x4000~1000], logical extent 0x0~1000, object #-1:7b3f43c4:::osd_superblock:0# 2019-01-31 15:12:31.889227 7f6ae7fdee40 -1 osd.74 0 OSD::init() : unable to read osd superblock 2019-01-31 15:12:32.508923 7f6ae7fdee40 -1 ** ERROR: osd init failed: (22) Invalid argument We've tried to fix it with ceph bluestore tool, but it didn't help. # ceph-bluestore-tool repair --deep 1 --path /var/lib/ceph/osd/ceph-74 repair success Is it possible to fix corrupted osd superblock?
