Hi more info,

   The ceph-volume lvm list, show the wrong osds for example:

   ====== osd.82 ======

  [block]       /dev/ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block-f96c826d-3570-4c78-9ef6-bea191589102

      block device              /dev/ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block-f96c826d-3570-4c78-9ef6-bea191589102
      block uuid                avfhQj-uiRt-ZwjG-4jkD-G4tg-a3BM-bcbUfc
      cephx lockbox secret
      cluster fsid              6f5a65a7-316c-4825-afcb-428608941dd1
      cluster name              ceph
      crush device class
      encrypted                 0
      osd fsid                  f96c826d-3570-4c78-9ef6-bea191589102
      osd id                    82
      osdspec affinity
      type                      block
      vdo                       0
      devices                   /dev/mapper/mpatha 



    the  /dev/mapper/mpatha  is linked to dm-29.
    The path ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block-f96c826d-3570-4c78-9ef6-bea191589102 does not exits

    I just try to create the path and link to dm-29:
    ln -s ceph-3b5662ac-854a-4954-aa44-8951feaa1840/osd-block-f96c826d-3570-4c78-9ef6-bea191589102 ../dm-29

    and reboot, but the path has disappear again

  Any advice is welcomed. Regards, I
