centos 7单机安装ceph并创建rbd块设备

1. 安装依赖包

新增阿里云源ceph下载地址

vim /etc/yum.repos.d/ceph.repo

[ceph]
name=ceph
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/x86_64/
gpgcheck=0
[ceph-noarch]
name=cephnoarch
baseurl=http://mirrors.aliyun.com/ceph/rpm-jewel/el7/noarch/
gpgcheck=0

yum makecache

yum -y install ceph ceph-deploy python-setuptools.noarch

2. 配置安装

mkdir /root/myceph && cd /root/myceph

ceph-deploy new localhost

echo -e 'osd_pool_default_size = 1 \nosd_pool_default_min_size = 1'>>ceph.conf

ceph-deploy install --release jewel localhost

3.监控组件启动

ceph-deploy mon create-initial

ceph-deploy admin localhost

4.创建osd

ceph-deploy osd create localhost:/dev/sdb

ceph-deploy osd create localhost:/dev/sdc

ceph-deploy osd list localhost  查看详情

5. 创建存储池，生成rbd盘

ceph osd pool create zc-rbd 16 16

rbd create myimage --size 10240 --pool zc-rbd

rbd ls --pool zc-rbd -l

modprobe rbd

rbd feature disable zc-rbd/myimage exclusive-lock object-map fast-diff deep-flatten

rbd map zc-rbd/myimage
