The current version of ovirt-engine in production environment is 4.3.5.5.
In order to prevent the ovirt-engine machine from being down, the management interface
cannot be used, according to the relevant link:
https://ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html
I backed it up using the command:
engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
I have prepared another machine as a spare machine. Once the ovirt-engine is down in the
production environment, the standby machine can be UP and the standby machine can manage
the ovirt-nodes.
According to the relevant links:
https://ovirt.org/documentation/install-guide/chap-Installing_oVirt.html
The ovirt-engine is installed on the standby machine.
After I have executed these three commands:
1. yum install
http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2. yum update
3. yum install ovirt-engine
I found that the ovirt-engine version of the standby machine is 4.3.6
So my question is:
1. The ovirt-engine version of the standby machine is 4.3.6, and the production
environment ovirt-engine version is 4.3.5.5, which command is used on the production
environment ovirt-engine machine:
engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
Files obtained after using the backup command on the ovirt-engine in the production
environment are restored using these two files under the standby computer. Will the
information on the ovirt-engine management interface of the standby computer be consistent
with the ovirt-engine of the production environment (eg data center, host, virtual
machine, etc.)?
2. Can the ovirt-engine of the standby machine be installed with version 4.3.5.5? How do I
need to modify the following three commands to get the backup machine to install the
version 4.3.5.5?
1. yum install
http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2. yum update
3. yum install ovirt-engine
