[ovirt-users] hosted-engine restore

[Gary Pedretty]

When attempting to do the restore to a clean engine install before engine setup is run as per the documentation, the restore ends with an error about restoring the history.




root at fai-kvm-engine backup]# engine-backup --mode=restore --file=/backup/ovirt-backup07302017.bak --log=/usr/local/share/ovirtbackup.log --provision-db --provision-dwh-db --restore-permissions
Preparing to restore:
- Unpacking file '/backup/ovirt-backup07302017.bak'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
- user 'ovirt_engine_history', database 'ovirt_engine_history'
Restoring:
- Engine database 'engine'
  - Cleaning up temporary tables in engine database 'engine'
  - Resetting DwhCurrentlyRunning in dwh_history_timekeeping in engine database
------------------------------------------------------------------------------
Please note:

The engine database was backed up at 2017-07-30 23:05:43.000000000 -0800 .

Objects that were added, removed or changed after this date, such as virtual
machines, disks, etc., are missing in the engine, and will probably require
recovery or recreation.
------------------------------------------------------------------------------
- DWH database 'ovirt_engine_history'
FATAL: Errors while restoring database ovirt_engine_history
[root at fai-kvm-engine backup]# 





If I continue and run engine-setup, then it fails with the following.

It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode

If the hosted-engine deployment that was backed up and is being restored, was created using the appliance, should I still follow this documentation and manually install the engine, run the restore, then do the engine-setup?  Or should I use the ovirt-engine-appliance and just run the restore before the engine-setup?
