Univention Bugzilla – Bug 50448
On the first page system setup should warn if RAM is insufficient
Last modified: 2019-11-27 14:20:07 CET
Since UCS 4.0 system setup shows a popup if the memory is insufficient. BUT the popup is shown, when entering the summary page, which is too late, because in the meantime system setup fails due to OutOfMemory. It should be shown on the first page (selection of location/language). Screenshot at Bug 36460: https://forge.univention.org/bugzilla/attachment.cgi?id=6771 Additionally the text should be adapted, too.
If easier to implement, it would also be OK to show a static page instead of the configuration wizard with a warning.
A fix has been implemented in git:fbest/50448-system-setup-ram-warning, which: 1. moves the pop up to a page * It's displayed on page 3, after the language and location selection (so that the message is translated) 2. Changes the "Next" button to a "Ignore" button 3. The product owner decided to also show a link to an SDB article which describes more information. The draft for this has been added in https://help.univention.com/t/minimum-ram-requirements-for-the-ucs-installation/13595. 4. The minimum values has already been raised from 512MB to 1GB in the past. Should it be raised even more? 5. The pop up dialog when entering the success page has been removed.

The updated EC2 image description recommends 2GB of RAM.

I recommend to define a limit of 1.8G. (if we define 2G we might see the warning in IaaS instances with 2GB as there are a few KB reserved) > TODO: update default minimum in > univention-system-setup/www/ApplianceWizard.js > update default minimum in > https://help.univention.com/t/minimum-ram-requirements-for-the-ucs- > installation/13595

So I guess it would be fine to set the memory minimum to 2048? var memory_min = Math.max(parseInt(this.ucr['system/setup/boot/minimal_memory'], 10) || 0, 2048); // The reported total memory is always a bit lower, than the actually installed amount: var memory_total_plus_margin = this.values.memory_total * 1.1; if (memory_min > memory_total_plus_margin) {....

OK for me!
