Hello everyone, I am Chen Jianhao, and you can call me Engineer Chen. I usually enjoy pondering technical issues and organize the pitfalls and fragmented thoughts I encounter at work into articles. Occasionally, I also share some work insights and life reflections.
oVirt 4.4.3 open sourcevirtualization platform: Creating a New (Local Host) Data Storage Domain
Data Storage Domain:The data storage domain is used to store virtual disk images and OVF files of virtual machines and templates in the data center, as well as to store snapshots of virtual machines.
The data storage domain cannot be shared across different data centers. Additionally, the type of data storage domain must match the type of data center; only after the data storage domain has been added to the data center can other types of storage domains be added.
ISO Storage Domain:Stores ISO image files and can be shared across different data centers. The ISO storage domain allows the data center to avoid using physical optical discs and other devices.
A total of two data centers are established, one with local storage type and the other with shared storage type.
Adding node C to the LocalDisk cluster
Data Storage Domain
Node C has pre-configured the folder
[root@nodeC vm]# mkdir -p /vm/vm
Configure access permissions. In a real production environment, security issues regarding permissions need to be considered. In this experiment, the permissions are directly configured to777.
[root@nodeC vmvm]# chmod -R 777 /vm/vm
Fill in the“path” as“/vm/vm”(Note that by default, only this path can be filled in; if you need to use another path, it must be configured first), as shown below:
Only data centers configured with data storage domains will be up
