Re: [ovirt-users] replace ovirt engine host

Hi, We had a consulting partner who did the same for our company. This is his procedure and worked great: How to migrate ovirt management engine Packages Ensure you have the same packages & versions installed on the destination hostas on the source, using 'rpm -qa | grep ovirt'. Make sure versions are 100%identical. Default setup Run 'engine-setup' on the destination host after installing the packages. Use the following configuration: 1. Backup existing configuration 2. On the source host, do: a. service ovirt-engine stop b. service ovirt-engine-dwhd stop c. mkdir ~/backup d. tar -C /etc/pki/ovirt-engine -czpf ~/backup/ovirt-engine-pki.tar.gz . e. tar -C /etc/ovirt-engine -czpf ~/backup/ovirt-engine-conf.tar.gz . f. cd /usr/share/ovirt-engine/dbscripts g. ./backup.sh h. mv engine_*.sql ~/backup/engine.sql 3. You may also want to backup dwh & reports: a. cd /usr/share/ovirt-engine/bin/ b. ./engine-backup.sh --mode=backup --scope=db --db-user=engine --db-password=XXX --file=/usr/tmp/rhevm-backups/engine-backup --log=/tmp/engine-backup.log c. ./engine-backup.sh --mode=backup --scope=dwhdb --db-user=engine --db-password=XXX --file=/usr/tmp/rhevm-backups/dwh-backup --log=/tmp/engine-backup.log d. ./engine-backup.sh --mode=backup --scope=reportsdb --db-user=engine --db-password=XXX --file=/usr/tmp/rhevm-backups/reports-backup --log=/tmp/engine-backup.log 4. Download these backup files, and copy them to the destination host. Restore configuration 1. On the destination host, do: a. service ovirt-engine stop b. service ovirt-engine-dwhd stop c. cd backup d. tar -C /etc/pki/ovirt-engine -xzpf ovirt-engine-pki.tar.gz e. tar -C /etc/ovirt-engine -xzpf ovirt-engine-conf.tar.gz f. tar -xvjf engine-backup g. tar -xvjf dwh-backup h. tar -xvjf reports-backup Restore Database 1. On the destination host do: a. su - postgres -c "psql -d template1 -c 'drop database engine;'" b. su - postgres -c "psql -d template1 -c 'create database engine owner engine;'" c. su - postgres d. psql e. \c engine f. \i /path/to/backup/engine.sql NOTE: in case you have issues logging in to the database, add the following line to the pg_hba.conf file: host all engine 127.0.0.1/32 trust 2. Fix engine password: a. su - postgres b. psql c. alter user engine with password 'XXXXXXX'; Change ovirt hostname On the destination host, run: /usr/share/ovirt-engine/setup/bin/ovirt-engine-rename NB: Restoring the dwh/reports database is similar to steps 5-7, but omitted from this document due to problems starting the reporting service. 2014-11-07 10:28 GMT+01:00 Sven Kieske <s.kieske(a)mittwald.de&gt;:
