4.2. Upgrading to Red Hat Virtualization Manager 4.3 with ovirt-fast-forward-upgrade
Procedure
Log in to the Manager machine and install the
ovirt-fast-forward-upgrade
tool:# yum install ovirt-fast-forward-upgrade
Run the following command to upgrade the Manager, while creating a backup of the current version:
# ovirt-fast-forward-upgrade --backup --backup-dir=/backup
NoteRed Hat recommends using the
--backup
and--backup-dir
options to create a backup of the current Manager. If a backup directory is not specified, the backup is saved in/tmp
.The
--backup
option is a wrapper for theengine-backup
tool and is equivalent to running the following command:# engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
To restore your backup, run
engine-backup
inrestore
mode:# engine-backup --mode=restore
See Backing Up and Restoring the Red Hat Virtualization Manager in the Administration Guide for details.
Alternatively, to upgrade without creating a backup, run the following command:
# ovirt-fast-forward-upgrade
-
If there are errors, check the log:
/var/log/ovirt-engine/ovirt-fast-forward-upgrade.log
.
You can now update the hosts.
