Hi Joseph,

Somehow I missed your email.

I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed.

Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊

For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again.

Too many CI/CD deployment failures, to leave the engine process fighting for resources.

Hi Marko,

=A0I have also had this problem on an oVirt 4.3 install - I could never=20
fix it and have not tried to upgrade to 4.4 yet - my workaround for now=20
(as you have deduced) is to just 'up' it while running so its hotswapped=20
in - annoying, but I think the best way around this without upgrade=20
would be to re-deploy the hosted engine defining the new resources using=20
an engine-backup - but again this is just as scary as in-place upgrade=20
lest you lock yourself out from your other running VMs in a production=20
environment.

=A0I plan to do it - I just need some time to set it up in a lab so I=20
know what to expect.

Thanks,
Joe

 Hi Marko, 
 
 =A0I have also had this problem on an oVirt 4.3 install - I could
 never fix it and have not tried to upgrade to 4.4 yet - my
 workaround for now (as you have deduced) is to just 'up' it while
 running so its hotswapped in - annoying, but I think the best way
 around this without upgrade would be to re-deploy the hosted engine
 defining the new resources using an engine-backup - but again this
 is just as scary as in-place upgrade lest you lock yourself out from
 your other running VMs in a production environment. 
 
 =A0I plan to do it - I just need some time to set it up in a lab so I
 know what to expect. 
 
 Thanks, 
 Joe

 Hi all,<o:p></o:p>
 =A0<o:p></o:p>
 Still testing in staging and I have not moved
 from updating RAM.<o:p></o:p>
 Initially, I made the change via Portal,
 updating defined memory of HE from 16384 to 32768. The
 change is instantly visible on VM when I execute
 free -m , but in the VM info it still says 16384. </sp=
an><o:p></o:p>
 I waited almost 4hours and this value did not
 get updated. Tried shutdown, remove GM, allow the HA to
 start the VM, it booted with 16384 allocated.<o:p></o:=
p>
 =A0<o:p></o:p>
 Than I did it again, and tried with Update OVF
 from storage domain where the HE disk is, same, no change.</s=
pan><o:p></o:p>
 =A0<o:p></o:p>
 Tried, updating memory again, migrating to
 another HA host =96 Update OVF , same thing, after reboot, th=
e
 memory is back to 16384.<o:p></o:p>
 =A0<o:p></o:p>
 Can somebody give me an advice where to look
 further? Again, making the change in memory amount is
 instant on the VM, but after reboot, its back to 16384.</span=
