KVM之virsh管理Storage pool

创建基于文件夹的存储池

基于文件夹的存储池：

[root@ubuntu01 ~]# mkdir /data/vm_pool
[root@ubuntu01 ~]# virsh pool-create-as --name vmdir_pool --type dir --target /data/vm_pool
Pool vmdir_pool created

基于文件夹的存储池：

[root@ubuntu01 ~]# mkdir /data/vmfs_pool
[root@ubuntu01 ~]# virsh pool-create-as --name vmfs_pool --type fs --source-dev /dev/sdb1 --source-format ext4 --target /data/vmfs_pool
Pool vmfs_pool created

查看存储池状态

[root@ubuntu01 ~]# virsh pool-list --all
 Name                 State      Autostart
-------------------------------------------
 vmdir_pool           active     no
 vmfs_pool            active     no  

[root@ubuntu01 ~]# virsh  pool-info vmdir_pool

[root@ubuntu01 ~]# virsh  pool-info vmfs_pool

在存储池中创建卷

[root@ubuntu01 ~]# virsh vol-create-as --pool vmdir_pool --name vm_disk01.raw --capacity 10G --allocation 1G --format raw
Vol vm_disk01.raw created

• --capacity 10G #总容量
• --allocation 1G #初始大小

查看存储池的卷信息

[root@ubuntu01 ~]# virsh vol-list [--pool] vmdir_pool

[root@ubuntu01 ~]# virsh vol-list [--pool] vmdir_pool --details
