CEPH 不同类型磁盘 加入不同pool

版本：(L版之前 需要手动修改CRUSH map)
# ceph --version
ceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous (stable)

因是测试环境 只在虚拟机上加了两块磁盘做OSD  将class修改了 一块为hdd  一块为ssd
#ceph osd tree
ID CLASS WEIGHT  TYPE NAME              STATUS REWEIGHT PRI-AFF 
-1       0.03998 root default                                   
-2             0     host 192.168.60.99                         
-5       0.03998     host control01                             
 1   hdd 0.01999         osd.1              up  1.00000 1.00000 
 0   ssd 0.01999         osd.0              up  1.00000 1.00000 


# ceph osd crush class ls
[
    "ssd",
    "hdd"
]


创建两条rule host分别指定为ssd/hdd
# ceph osd crush rule create-replicated rule-ssd default  host ssd
# ceph osd crush rule create-replicated rule-hdd default  host hdd


修改pool绑定的rule
# ceph osd pool set images crush_rule rule-hdd
# ceph osd pool set backups crush_rule rule-hdd
# ceph osd pool set volumes crush_rule rule-ssd
# ceph osd pool set vms crush_rule rule-ssd

查看绑定后信息
# ceph osd pool ls detail 
pool 1 'images' replicated size 1 min_size 1 crush_rule 3 object_hash rjenkins pg_num 128 pgp_num 128 last_change 60 flags hashpspool stripe_width 0 application rbd

上传一个镜像文件到images pool中 测试是不是到指定的OSD
