1、确认需要更换的磁盘对应的盘符、OSD ID ;
    root@Ceph-BA-04-S2-60:~# df -h |grep 17
    /dev/sdp3 1.1T 566G 551G 51% /var/lib/ceph/osd/ceph-17
    2、确认磁盘对应的槽位;
    root@Ceph-BA-04-S2-60:~# ll /dev/disk/by-path/ |grep sdp
    lrwxrwxrwx 1 root root 9 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0 -> ../../sdp
    lrwxrwxrwx 1 root root 10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part1 -> ../../sdp1
    lrwxrwxrwx 1 root root 10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part2 -> ../../sdp2
    lrwxrwxrwx 1 root root 10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part3 -> ../../sdp3
    3、确认主机SN;
    root@Ceph-BA-04-S2-60:~# dmidecode -s system-serial-number
    HVNHB
    4、设置OSD Flag;
    ceph osd out 17
    5、查看集群状态;
    ceph -s
    6、关闭对应的OSD进程;
    stop cep-osd id=17
    7、从CrshMap中移除OSD;
    ceph osd crush remove osd.17
    8、删除OSD认证信息;
    ceph auth del osd.17
    9、从集群中移除OSD;
    ceph osd rm 17
    10、卸载挂载点;
    umount /var/lib/ceph/osd/ceph-17
    11、更换新的磁盘。。。略;

    12、格式化新磁盘;
    ceph-deploy disk zap Ceph-BXXAXX-04-S2-60.domain.tld:sdp
    13、创建OSD;
    ceph-deploy osd create Ceph-BXXAXX-04-S2-60.domain.tld:sdp
    14、调整CrushMap;
    ceph osd crush add osd.17 1.17 root=sata pod=sata-pod-01 chassis=sata-chassis-01 host=Ceph-B
    A**-04-S2-60-sata
    15、优化挂载参数;
    mount -o remount,nobarrier /var/lib/ceph/osd/ceph-17
