KVM存储池配置

1. 定义存储池目录

[root@ddd-s-8 kvmimg]# virsh pool-define-as vmdisk --type dir --target /data/kvmimg/
Pool vmdisk defined

2.创建已定义的存储池
[root@ddd-s-8 kvmimg]# virsh pool-build vmdisk
Pool vmdisk built

 

 3.查看已定义的存储池，存储池不激活无法使用

[root@ddd-s-8 kvmimg]# virsh pool-list --all   #查看所有存储池
Name                 State      Autostart 
-----------------------------------------
default              active     yes       
vmdisk               inactive   no        

[root@ddd-s-8 kvmimg]# 
[root@ddd-s-8 kvmimg]# virsh pool-info vmdisk    #查看vmdisk存储池信息
Name:           vmdisk
UUID:           6e80ce65-c13c-aac2-02fe-c370b6463109
State:          inactive
Persistent:     yes
Autostart:      no

 

4.激活并自动启动已定义的存储池

[root@ddd-s-8 kvmimg]# virsh pool-autostart vmdisk
Pool vmdisk marked as autostarted

[root@ddd-s-8 kvmimg]# virsh pool-start vmdisk
Pool vmdisk started

[root@ddd-s-8 kvmimg]# virsh pool-info vmdisk     
Name:           vmdisk
UUID:           6e80ce65-c13c-aac2-02fe-c370b6463109
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       774.28 GiB
Allocation:     55.51 GiB
Available:      718.78 GiB

[root@ddd-s-8 kvmimg]# virsh pool-list --all      
Name                 State      Autostart 
-----------------------------------------
default              active     yes       
vmdisk               active     yes

 

5.在存储池中创建qcow2虚拟机存储卷,之后就可以直接使用qcow2磁盘文件安装系统了

[root@ddd-s-8 kvmimg]# virsh vol-create-as vmdisk test06.qcow2 20G --format qcow2         
Vol test06.qcow2 created

6.删除存储池命令整理
[root@ddd-s-8 kvmimg]# virsh vol-delete --pool vmdisk test06.qcow2     #删除刚刚创建的
Vol test06.qcow2 deleted

[root@ddd-s-8 kvmimg]# ll
total 56836660
-rw-r--r-- 1 root root 17911579136 Jul  7 18:27 test01.qcow2
-rw-r--r-- 1 root root 37823512576 Jul  7 15:31 test02.qcow2

[root@ddd-s-8 kvmimg]# 
[root@ddd-s-8 kvmimg]# virsh pool-destroy vmdisk   #取消激活存储池
[root@ddd-s-8 kvmimg]# virsh pool-delete vmdisk    #删除存储池定义的目录/data/kvmimg
[root@ddd-s-8 kvmimg]# virsh pool-undefine vmdisk   #取消定义存储池
