[ovirt-users] Reinstalling a new oVirt Manager

[VONDRA Alain]

Hi,
The plan using import Domain seems to be OK, but when I finalize the importation of a Data/iScsi I have this alert :

Storage Domain(s) are already attached to a Data Center. Approving this operation might cause data corruption if both Data Centers are active.

How can I detach this domain to a non visible old Data Center ??
Can I pass this alert without data lost ?

Thanks
Alain

I plan to reinstall on a cloned VM from the original one, I have cleaned the previous version, and made an engine-setup.
So I have backups from the previous Manager, I can backup to the new one.
But, reading the overt-engine-backup, it seems to be possible only before doing engine-setup.
Is that right or may I launch a backup after an engine-setup ?
An engine-clean is enough to use engine-backup ?

Thanks

Are you planning to install on a new host/VM?

You have basically two alternatives:
A. backup the DB and restore it on the new engine as described here:
http://www.ovirt.org/Ovirt-engine-backup

B. Start from scratch with a new engine on a new DB and re-import existing storage domains:
http://www.ovirt.org/Features/ImportStorageDomain

Option B involves a lot of manual steps but it could be also used as a disaster recovery flow when the DB is for any reasons lost or corrupted.
