Hi Joseph,
Can you check the current OVF interval , as I set mine to 5 min :)
To check use (at the HostedEngine):
engine-config -g OvfUpdateIntervalInMinutes

Based on my history, I set:
engine-config -s OvfUpdateIntervalInMinutes=5

The problems I saw before:
1.  OVF was  updated  faster , but not for 5 min (still faster than the default 
value)
2. In my case OVF was corrupted,  so I just removed it. I'm not sure if OVF 
updates  if it is good (no coruption). Still it's worth trying


P.S: My OVF updated after 2-3 hours with the

[ovirt-users] Re: HostedEngine add more RAM

2020-05-18 Thread Joseph Goldman 

Using oVirt 4.3.7  - testing on 2 diff environments.

So editing via UI and waiting some days, or using the below process both 
still don't work.


What seems to happen is it does update the running HE with the new RAM 
amount while booted, but the OVF is not updating because as soon as the 
VM reboots its back to original value of 4GB, so the increase is only 
applicable for that current running session.


When editing in the UI it seems it does not save, I can go straight back 
into the VM info or edit screen and it has instantly reverted back to 
4096mb even though the VM itself now has 8 (trying to change from 4->8).


When saving, even the log says "Hotset memory: changed the amount of 
memory on VM HostedEngine from 4096 to 4096" so it seems the system is 
actively limiting my ability to update the HE - this happens both in 
global maintenance mode and no maintenance mode.


On a customers cluster - I am getting a lot of EngineBadHealth and the 
HA agent is constantly moving it around on me, I fear because of RAM, so 
I'd like the OVF to update so on fresh boot it can keep a new RAM config.


Any help appreciated.

Joe

From 4.2 you don't need to wait, you should be able to update the HE 
memory via UI:

1. Enable global maintenance
2. Change HE VM memory via UI
3. On the HE, run: # hosted-engine --vm-shutdown
4. Wait for HE VM to be down: # hosted-engine --vm-status
5. Start HE VM: # hosted-engine --vm-start
6. Disable global maintenance

Have you tried  to add  more  RAM via UI and leave the VM for a
day /even 2/ for the OVF to be updated ?

I know that there  is an option to force  faster OVF updates , but
it's still  slower than the defined frequency.

[ovirt-users] Re: [Feedback needed] oVirt 4.4.0 Test week

2020-05-18 Thread Jiří Sléžka 
Hi,

I am a bit late but today a tried to install single host HCI with gluster.

I am not sure if it is currently supported but

* I installed

dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm
dnf module enable -y javapackages-tools pki-deps postgresql:12 389-ds
dnf install ovirt-engine-appliance vdsm-gluster

* I prepared host by gdeploy (from external Fedora workstation because I
didn't find gdeploy in any CentOS8 repo)

* I tried to instal ovvirt via

ovirt-hosted-engine-setup

...but process failed with

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg":
"Unable to start service libvirtd: Job for libvirtd.service failed
because the control process exited with error code.\nSee \"systemctl
status libvirtd.service\" and \"journalctl -xe\" for details.\n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing
ansible-playbook

In messages log is mentioned

...
May 18 17:04:40 ovirt-hci01 journal[8062]: Cannot read CA certificate
'/etc/pki/CA/cacert.pem': No such file or directory
May 18 17:04:40 ovirt-hci01 systemd[1]: libvirtd.service: Main process
exited, code=exited, status=6/NOTCONFIGURED
...

There is no /etc/pki/CA directory. I think CA should be installed during
ovirt-hosted-engine-setup, isn't it? Should I do that manually? How?

Cheers,

Jiri

[ovirt-users] Re: Migrate hosted engine to standalone host

2020-05-18 Thread Anton Louw via Users 
Hello,

I am not sure if the below thread went missing somewhere. Just to add on as 
well, when moving the hosted engine to a standalone host, will the process look 
similar to the below:

Backup and remove Hosted Engine:

1. Backup Hosted Engine (engine-backup --scope=all --mode=backup --file=Full 
--log=Log_Full)
2. Download the backup files from HE using WinSCP
3. Enable global Maintenance (hosted-engine --set-maintenance --mode=global)
4. Power down hosted engine (hosted-engine --vm-shutdown)

-
Redeploy Hosted Engine:

Build new CentOS VM in another environment
*Same IP
*Same name
*Same resources

1. sudo yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm
2. sudo yum install -y ovirt-engine
3. Copy backup files to newly deployed CentOS VM
4. engine-backup --mode=restore --file=Full --log=Log_Full --provision-db 
--provision-dwh-db --restore-permissions
5. after retore has completed, run engine-setup

Or are there any additional steps I need to take? I have tried this in my  one 
lab environment, and it works without any issues, however when trying this on 
my second lab environment, everything shows as “down”, ie. Hosts, Data Center 
and Storage Domains.

Subject: [ovirt-users] Migrate hosted engine to standalone host


Hi All,

So I have been playing around a bit, and I would just like some recommendations.

I moved my HE from an oVirt node to my VMware environment, basically running as 
a standalone host now. Is there anything I should look out for?

I can see there is a problem when configuring the HE after the move, where it 
says that global maintenance is not enabled. How will this work if the hosted 
engine is not sitting on a oVirt node anymore?

Any feedback\suggestions will be greatly appreciated.

Thanks
