列出对象： ceph-objectstore-tool --op list --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal

列出pg： ceph-objectstore-tool --op list-pgs --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal

导出pg： ceph-objectstore-tool --op export --pgid 1.1 --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal --file /tmp/export/sdb1/1.1

导入pg： ceph-objectstore-tool --op import --data-path /var/lib/ceph/osd/ceph-4 --journal-path /var/lib/ceph/osd/ceph-4/journal --file /tmp/export/sdb1/1.1

列出某个pg的信息： [root@inspur306 sdb1]# ceph-objectstore-tool --op info --pgid 1.1 --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal

列出某个对象的信息： ceph-objectstore-tool --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal "["1.33",{"oid":"10000000003.0000000b","key":"","snapid":-2,"hash": 3095299315,"max":0,"pool":1,"namespace":""}]" list-atttrs

将一个对象导出为文件： ceph-objectstore-tool --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal "["1.33",{"oid":"10000000003.0000000b","key":"","snapid":-2,"hash": 3095299315,"max":0,"pool":1,"namespace":""}]" get-bytes /tmp/file

删除一个对象： ceph-objectstore-tool --data-path /tmp/data/sdb1 --journal-path /tmp/data/sdb1/journal "["1.33",{"oid":"10000000003.0000000b","key":"","snapid":-2,"hash": 3095299315,"max":0,"pool":1,"namespace":""}]" remove
