ceph
，Benefiting from its excellent performance and scalability,
Ceph distributed storage is also confronting the problems, i.e.
the unnecessary transfer of the data leading to the increasing
consumption of the system which is triggered by the additions
and deletions on the equipment. Aiming at the implement
method of Ceph in system algorithm and logical layout, this
paper has carried on research, analyzing its defects in the
aspect of data transfer and resource consumption and puts
forward the handling method of the failure node when the
cluster storage device fails. Through the establishment of the
cluster device flag in the process of data transfer, the
optimized scheme of the data migration in the environment of
production is realized, and the utilization of the system
resources is improved. The experimental test results have
shown that the scheme can reduce about the 30% -40% of
transfer volume, effectively lower the resources consumption
of Ceph distributed storage, as well as prevent invalid and
excessive data transfer.
