Hi!

I am trying to configure ovirt-engine and having a problem that it

is some information. Thanks.


The system is Fedora17/_ppc64_ (not x86 if it matters) with my 3.6
kernel.

Below is the console output after running "postgresql-setup
initdb" and
"engine-setup" and the log produced by the "engine-setup" script.

The right way to start/stop services in Fedora 17 is using the
systemctl
tool:

systemctl start postgresql.service
systemctl stop postgresql.service

The postgresql service no longer uses SystemV scripts to
start/stop, it
uses systemctl instead, that is why there is no
/etc/init.d/postgresql
script.

Yes I noticed that while googling. The question is what do I do to
make
engine-setup not failing. It is starting services, one-by-one, and it
stops
in the middle of a sequence as postgresql fails because engine-setup
uses
old postgresql script. ovirt.org uses FC17 so I wonder if there is
some
fix/workaround.

Juan, I think that we should have a BZ on that since the code in 
engine-db-install.sh is using the old service invocation format and does not 
distinguish between different Fedora version

I agree, we should use "service postgresql ..." instead of
"/etc/init.d/postgresql ...", as that works in all versions of Fedora
and in RHEL as well.

However I think that we already have logic in the script to check if
systemd is available, and in that case we don't use /etc/init.d. Maybe
this logic is failing in the ppc version of Fedora.


Where exactly does this code beside? I did grep by the error message but have not found the place.



If you still have problems to create the database please check the
database installation log file, should be named as follows:

/var/log/ovirt-engine/engine-db-install-2012_11_12_16_07_01.log


Database is fine...

#engine db installer log file on vpl2.ozlabs.ibm.com
