Hi,
We had a consulting partner who did the same for our company. This is his p=
rocedure and worked great:
How to migrate ovirt management engine
Packages
Ensure you have the same packages & versions installed on the destination h=
ostas on the source, using 'rpm -qa | grep ovirt'. Make sure versions are 1=
00%identical.
Default setup
Run 'engine-setup' on the destination host after installing the packages. U=
se
the following configuration:
1. Backup existing configuration
2. On the source host, do:
You might want your consultant take a look on [1]...
Steps a-3d:
engine-backup mode=3Dbackup --file=3D~/ovirt-engine-source --log=3Dbackup.l=
og
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=3Dbackup --scope=3Ddb --db-user=3Dengine --=
db-password=3DXXX --file=3D/usr/tmp/rhevm-backups/engine-backup --log=3D/tm=
p/engine-backup.log
c. ./engine-backup.sh --mode=3Dbackup --scope=3Ddwhdb --db-user=3Dengine=
--db-password=3DXXX --file=3D/usr/tmp/rhevm-backups/dwh-backup --log=3D/tm=
p/engine-backup.log
d. ./engine-backup.sh --mode=3Dbackup --scope=3Dreportsdb --db-user=3Den=
gine --db-password=3DXXX --file=3D/usr/tmp/rhevm-backups/reports-backup --l=
og=3D/tmp/engine-backup.log
4. Download these backup files, and copy them to the destination host.
Restore configuration
1. On the destination host, do:
Again, steps a-h, basically
engine-setup
engine-cleanup
engine-backup mode=3Drestore --file=3D~/ovirt-engine-source --log=3Dbackup.=
log
also, I would run a second
engine-setup
After that, you should be good to go..
Of course, depending on your previous engine setup this could be a little m=
ore complicated. Still, quite strait forward.
[1] http://www.ovirt.org/Ovirt-engine-backup
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
=20
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<http://127.0.0.1/32> tr=
ust
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 fro=
m
this document due to problems starting the reporting service.
