流程

1. 验证适当的 OSD 是否停机：

   语法

   systemctl status ceph-osd@$OSD_NUMBER

   示例

   [root@osd ~]# systemctl status ceph-osd@1

2. 列出对象映射：

   语法

   ceph-objectstore-tool --data-path $PATH_TO_OSD --pgid $PG_ID \
   $OBJECT \
   list-omap

   示例

   [root@osd ~]# ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-0 --pgid 0.1c \
   '{"oid":"zone_info.default","key":"","snapid":-2,"hash":235010478,"max":0,"pool":11,"namespace":""}' \
   list-omap
