操作
1.执行前奏脚本格式非常重要格式不对无法执行
- name: create volume group #任务名hosts: group1 tasks:- name: Create partition for LVM community.general.parted: #引用模块device: /dev/nvme0n2 #硬盘设备路径number: 1 # 分区序号flags: [ lvm ] #分区标记state: present #操作方式present创建 absent删除 info查信息(默认part_start: 1MiB #分区起始位置part_end: 2GiB #分区结束位置- name: create research vg lvg:vg: research #卷组名称pvs: /dev/nvme0n2p1 #指定物理卷
- name: create volume grouphosts: group2tasks:- name: Create partition for LVMcommunity.general.parted:device: /dev/nvme0n2number: 1flags: [ lvm ]state: presentpart_start: 1MiBpart_end: 1GiB- name: create research vglvg:vg: researchpvs: /dev/nvme1n2p1
2.创建脚本lv.yml 按照以下的格式 datalvm逻辑卷名称research卷组名称
