Hi Yanjun,
Please disregard Chengwei's message. The page he linked to clearly
states that hashpspool is supported in kernels 3.9 and above...
Your CRUSH tunables are set to jewel (tunables5). As per [1],
tunables5 are supported starting with kernel 4.5. You need to either
upgrade your kernel or set your tunables to legacy with
$ ceph osd crush tunables legacy
[1] http://docs.ceph.com/docs/master/rados/operations/crush-map/#which-client-versions-support-crush-tunables5
Thanks,
Ilya
