Associated release criterion
This test case is associated with the Fedora_42_Beta_Release_Criteria#image-size-requirements release criterion. If you are doing release validation testing, a failure of this test case may be a breach of that release criterion. If so, please file a bug and nominate it as blocking the appropriate milestone, using the blocker bug nomination page.


Description

All ISO images must be small enough to fit on the corresponding media. This test does not apply to disk image files (e.g. ARM and Cloud disk images): their compressed size is not relevant to their deployment, and restrictions on their uncompressed size are applied during the compose process.


How to test

Automated checking

You can run this test easily with the relval tool. Run dnf install relval to install it, if you do not already have it, on any Fedora system.

This will run the size checks for the current compose, and report them to the wiki: 

$ relval size-check --username <fas_user_name>

To run the checks for a specific compose, you can run: 

$ relval size-check --release=NN --milestone=[Alpha,Beta,Final] --compose=COMPOSE --username <fas_user_name>

Example: 

$ relval size-check --release=24 --milestone=Beta --compose=1.6 --username <fas_user_name>

for checking 24_Beta-1.6/ compose directory.

Manual checking

If you have the image downloaded locally, view the size of the file in bytes like this: 

$ du -b Fedora-Server-netinst-x86_64-21_Alpha.iso
419430400	Fedora-Server-netinst-x86_64-21_Alpha.iso

If you don't have the image downloaded locally, query the size using HTTP headers like this: 

$ curl -sI http://server/image.iso | grep Content-Length
Content-Length: 419430400

Check all ISO files available for this specific compose.

Expected Results

  1. The size of checked images is less than or equal to the size specified as maximum size at Releases/42/ReleaseBlocking (or at Releases/42/Spins for spins not covered on the former page).
