[ceph-users] Question about the Ceph Pluins Jerasure, reed_sol_r6_op not work for OSD binding

[朱轶君]

HI, Experts and Supporters

I am newer for CEPH so maybe the the question looks simple and stupids sometimes

i want to create the Ceph Cluster with the algorithm of Reed solomn Raid 6, 
Jerasure has the plugin "reed_sol_r6_op"

but it seems i can't bind the pool with the OSDs

the steps:

[cosceph@CEPH-1 erasure-code]$ ceph osd erasure-code-profile get Yijun-R6-Reed
directory=/usr/lib64/ceph/erasure-code
k=4
m=2
plugin=jerasure
technique=reed_sol_r6_op
~~~~~~~~~~~~~~~~~~~~~~
[cosceph@CEPH-1 erasure-code]$ ceph osd crush rule dump Yijun-Ruleset
{
    "rule_id": 1,
    "rule_name": "Yijun-Ruleset",
    "ruleset": 1,
    "type": 3,
    "min_size": 3,
    "max_size": 3,
    "steps": [
        {
            "op": "set_chooseleaf_tries",
            "num": 5
        },
        {
            "op": "set_choose_tries",
            "num": 100
        },
        {
            "op": "take",
            "item": -1,
            "item_name": "default"
        },
        {
            "op": "chooseleaf_indep",
            "num": 0,
            "type": "host"
        },
        {
            "op": "emit"
        }
    ]
}
~~~~~~~~~~~~~~~~~~~~~~~~

[cosceph@CEPH-1 my-cluster]$  ceph osd pool create yijun-R6 266 266 erasure 
Yijun-R6-Reed Yijun-Ruleset

~~~~~~~~~~~~~~~~~~~~~~~~
then Ceph health show "HEALTH-WARN" with no pgs binded

[cosceph@CEPH-1 my-cluster]$ ceph status
    cluster ae1ef013-2acd-4ac5-86d2-9ec224a306ef
     health HEALTH_WARN
........
....
....

any thing that you can give me for the hint for suggestions??

thanks
