[ovirt-users] Re: Can't connect "https://FQDN/ovirt-engine" after reinstall ovirt-engine

2019-03-21 Thread exclim89
On the new system, I restored from the backup ovirt engine 4.1. Restored 
without errors
engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db
--provision-dwh-db --restore-permissions
 
Also restored /etc/pki from backup. I did not know what should be the rights to 
the
folders, now they are:
drwxr-xr-x. 7 rootroot 213 мар 21 06:17 CA

Hi,

Are you the same person sending an email with identical subject, but
from a different (similar) email address? Please see my answer to that
one. Thanks.

Please provide more details. What exactly did you do?

If it's something like:

yum install ovirt-engine
engine-setup
yum remove ovirt-engine
yum install ovirt-engine

then:
1. Recovering from that is not supported nor tested, so take the
following with a grain of salt.
2. The biggest damage from 'yum remove' is removal of pki. You should
find a backup, though, in /etc/pki/ovirt-engine-backups/something. You
can try to restore that to /etc/pki/ovirt-engine and see what happens.
3. You can also simply try running 'engine-setup'. It should recreate
pki. This will also then require reinstalling all hosts (or at least
"Enroll Certificate").
4. Alternatively, you can try using your 4.1 engine-backup. Best way
is by installing 4.1, restoring the backup, then upgrading.
Alternatively, you can patch engine-backup to not refuse restoring the
older version, see e.g.
https://bugzilla.redhat.com/show_bug.cgi?id=1425788 .
5. Alternatively, you can compare your current /etc with the backup
you took, and carefully decide which files should be restored. Then
you can try running 'egnine-setup' and see what happens. Obviously,
this is the best option in terms of chances for success, but is also
the most time-consuming.

Good luck and best regards,
