ceph-deploy部署bluestore

环境描述：ceph1和ceph2两个服务器（其中ceph1已经安装好了ceph-deploy）

                 每一个服务器上各一块S3500 SSD、两块日立1T的HDD盘

                 先后端和管理网络合一：分别为128.128.128.九、128.128.128.10

一、在/etc/hosts中增长：

128.128.128.9  ceph1
128.128.128.10 ceph2

二、经过

ssh-keygen和ssh-copy-id

使节点之间免密

三、在ceph1中新建一个目录，保留配置文件

mkdir /root/mycluster

cd /root/mycluster

四、安装ceph

ceph-deploy install ceph1 ceph2

五、安装mon

ceph-deploy new ceph1

六、修改ceph.conf配置文件

public_network = 128.128.128.0/24
cluster_network = 128.128.128.0/24

enable experimental unrecoverable data corrupting features = bluestore rocksdb debug_white_box_testing_ec_overwrites
bluestore block db size = 10737418240  #10G
bluestore block wal size = 10737418240  #10G
osd objectstore = bluestore
mon_allow_pool_delete = true
rbd_cache = false

[osd]
bluestore = true

七、初始化mon

ceph-deploy mon create-initial

若须要增长mon

ceph-deploy add mon ceph2

八、格式化分区

ceph-deploy zap {ceph-node}:{dest-disk}

例如：
ceph-deploy zap ceph1:/dev/sdb

九、将ceph.bootstrap-osd.keyring拷贝到/var/lib/ceph/bootstrap-osd/下，并命令为ceph.keyring

cp /home/mycluster/ceph.bootstrap-osd.keyring /var/lib/ceph/bootstrap-osd/ceph.keyring

或
scp /home/mycluster/ceph.bootstrap-osd.keyring ceph2：/var/lib/ceph/bootstrap-osd/ceph.keyring

十、增长osd

ceph-disk prepare  --bluestore --block.db /dev/sdb  --block.wal /dev/sdb /dev/sdc

其中：/dev/sdb为SSD盘，/dev/sdc为HDD盘
