HostedEngine add more RAM
Hi List, I'm having troubles adding more RAM to my HostedEngine VM. When the cluster first got up and running I only had a little bit of RAM so I only gave the HE 4GB, but i'm constantly getting BadHealth alerts so I want to up it to 8GB. I have tried multiple ways - mostly any time i edit the HE VM through the UI it simply reverts back to 4096MB RAM, never upgrades to 8192MB. I have tried with global HA maintenance on as well but no luck. No errors, it saves as if it has completed the action but when I re-open the VM (or even after a fresh boot) it has simply reverted back to 4096MB. Any help appreciated. Thanks, Joe

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. Best Regards, Strahil Nikolov
Which oVirt version are you using? 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 On Sat, May 16, 2020 at 1:46 PM Strahil Nikolov via Users <users@ovirt.org> wrote:

I'm using 4.3.9 . Let's see the author's output. Beest Regards, Strahil Nikolov
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 On 17/5/20 8:09 pm, Asaf Rachmani wrote:

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 setting above, but I think it was a bug to take so much time. Best Regards, Strahil Nikolov
