Description John Matthews 2015-09-08 17:41:53 UTC

Description of problem:

This RFE came about when an install was performed on a host with only 8GB of memory.  The install proceeded and errors were seen during content synchronization.  The errors were likely the result of running with not enough memory available.

The minimal requirements are 12GB which is covered in documentation.

To help a user understand this and avoid a bad experience we'd like to enforce a check for pre-reqs when the ISO is running, in case they missed reading the minimal reqs in the docs.

Ideally we could execute a script to check:
 - RAM is sufficient
 - Hard Drive space is sufficient


Thinking is this would be part of the ISO installer, so it'd be integrated with anaconda.  If that proves too difficult we could add a warning in fusor-installer when first run.

Comment 1 Derek Whatley 2016-07-12 20:26:46 UTC

After some discussion with John Matthews, putting the requirement-check-script in fusor-installer and fusor-undercloud-installer rather than Anaconda seem to be the correct solution for now so that the ISO build process is not complicated.

Comment 7 Derek Whatley 2016-07-25 15:49:32 UTC

Made changes to fusor-installer and fusor-undercloud-installer to implement RFE.

Bringing this back to MODIFIED so that it can be brought into the compose.

Comment 9 Derek Whatley 2016-08-05 15:05:47 UTC

Joseph Magen reported an issue with the RAM check detecting 0MB.

I switched the check over to "free -m" instead of "dmidecode -t 17" to prevent similar problems in the future.

Comment 10 John Matthews 2016-08-05 17:18:14 UTC

Will be in compose 8/5

Comment 11 James Olin Oden 2016-08-08 19:28:19 UTC

Verified with QCI-1.0-RHEL-7-20160806.t.0

Tested:
- installing with 8Gb of RAM.
- installing with 2 cores.
- installing with 1 core.
- installing with too little disk storage.

All scenarios passed.
