If this is really the last copy of important data: consider making a full raw clone of the disk before running any ceph-objectstore-tool commands on it and consider getting some professional help if you are not too familiar with the inner workings of Ceph. That being said, it's basically just: ceph-objectstore-tool --bluestore --op export --pg <pgid> --data-path /var/lib/ceph/osd/ceph-XX --file <pgid> and --op import into the new OSD. I don't think there's a command for all PGs at once, so you'll have to iterate over the broken PGs (or --op list-pgs) good luck. Paul -- Paul Emmerich Looking for help with your Ceph cluster?
