linlink~文档搭建存储节点(实践)
为计算节点增加一块120G的硬盘(关机状态下)，取名字为cinder
创建卷组
查看磁盘信息
lsblk创建LVM物理卷组
将硬盘初始化为物理卷
pvcreate /dev/sdbvgcreate cinder-volumes /dev/sdb编辑lvm配置文件
cp /etc/lvm/lvm.conf /etc/lvm/lvm.conf.backvi /etc/lvm/lvm.confdevices里添加一个filter
devices {
filter = ["a/sdb/"]
}启动LVM元数据服务
systemctl enable lvm2-lvmetadsystemctl start lvm2-lvmetadsystemctl status lvm2-lvmetad安装及配置Cinder服务
安装相关软件包
yum -y install openstack-cinder targetcli python-keystone备份及编辑文件
cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.backgrep -Ev '^$|#' /etc/cinder/cinder.conf.back > /etc/cinder/cinder.confvi /etc/cinder/cinder.conf修改[database]部分
