Greetings,
Exploring hosting my engine and ovirt_engine_history db's on my
dedicated PostgreSQL server.
This is a 9.5 install on a beefy box from the postgresql.org yum repos
that I'm using for other SQL needs too. 9.5.12 to be exact. I set up the
database just as the documentation says and I'm doing a fresh install of
my engine-setup.
During the install, right after I give it the details for the remote I
get this error:
[ ERROR ] Please set:
server_version =3D 9.5.9
in postgresql.conf on 'None'. Its location is usually
/var/lib/pgsql/data , or somewhere under /etc/postgresql* .
Huh?
Um. OK.
$ grep ^server_version postgresql.conf
server_version =3D 9.5.9
$ systemctl restart postgresql-9.5.service
LOG: syntax error in file "/var/lib/pgsql/9.5/data/postgresql.conf"
line 33, n...n ".9"
FATAL: configuration file "/var/lib/pgsql/9.5/data/postgresql.conf"
contains errors
Well that didn't work. Let's try something else.
$ grep ^server_version postgresql.conf
server_version =3D 9.5.9
$ systemctl restart postgresql-9.5.service
LOG: parameter "server_version" cannot be changed
FATAL: configuration file "/var/lib/pgsql/9.5/data/postgresql.conf"
contains errors
Whelp. That didn't work either. I can't seem to find anything in the
oVirt docs on setting this.
How am I supposed to do this?
Thanks!
~Stack~

Re: Scheduling a Snapshot of a Gluster volume not working within Ovirt
by Mark Betham
Hi Sahina,
Many thanks for your response and apologies for my delay in getting back to you.
> How was the schedule created - is this using the Remote Data Sync Setup under Storage domain?
Ovirt is configured in ‘Gluster’ mode, no VM support. When snapshotting we are taking a snapshot of the full Gluster volume.
To configure the snapshot schedule I did the following;
Login to Ovirt WebUI
From left hand menu select ‘Storage’ and ‘Volumes'
I then selected the volume I wanted to snapshot by clicking on the link within the ‘Name’ column
From here I selected the ‘Snapshots’ tab
From the top menu options I selected the drop down ‘Snapshot’
From the drop down options I selected ‘New’
A new window appeared titled ‘Create/Schedule Snapshot’
I entered a snapshot prefix and description into the available fields and selected the ‘Schedule’ page
On the schedule page I selected ‘Minute’ from the ‘Recurrence’ drop down
Set ‘Interval’ to every ’30’ minutes
Changed timezone to ‘Europe/London=(GMT+00:00) London Standard Time’
Left value in ‘Start Schedule by’ at default value
Set schedule to ‘No End Date’
Click 'OK'
Interestingly I get the following message on the ‘Create/Schedule Snapshot’ page before clicking on OK;
Frequent creation of snapshots would overload the cluster
Gluster CLI based snapshot scheduling is enabled. It would be disabled once volume snapshots scheduled from UI.
What is interesting is that I have not enabled 'Gluster CLI based snapshot scheduling’.
After clicking OK I am returned to the Volume Snapshots tab.
From this point I get no snapshots created according to the schedule set.
At the time of clicking OK in the WebUI to enable the schedule I get the following in the engine log;
2018-05-14 09:24:11,068Z WARN [org.ovirt.engine.core.dal.job.ExecutionMessageDirector] (default task-128) [85d0b16f-2c0c-464f-bbf1-682c062a4871] The message key 'ScheduleGlusterVolumeSnapshot' is missing from 'bundles/ExecutionMessages'

The original log file is no longer present, so I removed the old schedule and created a new schedule, as per the instructions above, earlier today. I have therefor attached the engine log from today. The new schedule, which was set to run every 30 minutes, has not produced any snapshots after around 2 hours.
Please let me know if you require any further information.
Many thanks,
Mark Betham.

I had spent some time troubleshooting the issue but felt it worthwhile to ensure I had a clean platform, void of any potential issues which may be there due to some of the previous work carried out. The platform was rebuilt and data re-ingested. It is probably worth mentioning that this environment will become our new production platform, we will be migrating data and services to this new platform from our existing Gluster storage cluster. The date for the migration activity is getting closer so available time has become an issue and will not permit another full rebuild of the platform without impacting delivery date.

The next step I took at this point was to setup the Geo-replication. This was brought online with no issues and data was seen to be synchronised without any problems. At this point the data re-ingestion was started and the new data was synchronised by the Geo-replication.

> The first step in bringing the snapshot schedule online was to validate that snapshots could be taken outside of the scheduler. Taking a manual snapshot via the OVirt portal worked without issue. Several were taken on both primary and secondary clusters. At this point a schedule was created on the primary site cluster via the Ovirt portal to create a snapshot of the storage at hourly intervals. The schedule was created successfully however no snapshots were ever created. Examining the logs did not show anything which I believed was a direct result of the faulty schedule but it is quite possible I missed something.

There were several loosely related support articles around snapshotting but none of the recommendations seemed to work. I did the same with manuals and again nothing that seemed to work. What I did find were several references to running snapshots along with geo-replication and that the geo-replication should be paused when creating. So I removed all existing references to any snapshot schedule, paused the Geo-repl and recreated the snapshot schedule. The schedule was never actioned and no snapshots were created. Removed Geo-repl entirely, remove all schedules and carried out a reboot of the entire platform. When the system was fully back online and no pending heal operations the schedule was re-added for the primary site only. No difference in the results and no snapshots were created from the schedule.

4.2.3 -- Snapshot in GUI Issue
by Zack Gould
Is there no way to restore a snapshot via the GUI on 4.2 anymore?
I can't take snapshot, but there's no restore option. Since the new GUI
design, it appears that it's missing?

sdk api and follow question / bug
by Peter Hudec
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Hi,
I'm using API to get stats about the VM using the FOLLOW syntax
described in
http://ovirt.github.io/ovirt-engine-api-model/4.2/#documents/003_common_
concepts/follow
In my case I list all VM with FOLLOWING
- 'statistics',
- 'nics.statistics',
- 'disk_attachments.disk.statistics'
On my env with about 50 VM the query took about 12s but the paring for
the monitoring system is easy.
The question is, it's better to split the code and use more queries as
the note in the API docs recommends? Not sure it will be faster and
less cpu intensive on the engine side.
Also the disk_attachments.disk.statistics on VMs seems to be broken,
I'm not getting the data on 4.2.2 installation. /using json syntax,
not xml/
regards
Peter

oVirt 4.2.3 on RHEL/CentOS 7.5
by Stefano Stagnaro
Hello,
since oVirt 4.2.3 release notes still indicates the availability for EL 7.4, I would like to know if the release has been tested for EL 7.5 yet and it's safe to install the VDSM on it (instead of oVirt Node).
Thank you.
