Hi James,
Proplem is why the Ceph not recommend using Device'UUID in Ceph.conf,
when, above error can be occur?
I think with the newer-style configuration, where your disks have
partition ids setup by ceph-disk instead of entries in ceph.conf, it
doesn't matter if they change names, as long as they mount point stays
the same.

Hi all
I have 3 OSDs, named sdb, sdc, sdd.
Suppose, one OSD with device /dev/sdc die => My server have only sdb,
sdc
at the moment.
Because device /dev/sdc replaced by /dev/sdd
Can you just use one of the /dev/disk/by-<something>/<identifier>
symlinks?
Eg
/dev/disk/by-uuid/153cf32b-e46b-4d31-95ef-749db3a88d02
/dev/disk/by-id/scsi-SATA_WDC_WD10EACS-00D_WD-WCAU66606660
Your distribution should allow for such things automatically, and if
not you should be able to add some udev rules to do it.
