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.
Test with relval
You can run this test easily with the relval tool. relval size-check will run the size checks for the 'current' compose, and report them to the wiki. To run the checks for a specific compose, you can run relval size-check --release=NN --milestone=(Alpha,Beta,Final) --compose=(T/RCN).


Description

All ISO images (i.e. Server-netinst.iso, Server-DVD.iso, Live-Workstation.iso and Live-KDE.iso) 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

  1. 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
  2. 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
  3. Check all ISO files available for this specific compose.

Expected Results

  1. The size of netinst and Cloud ISO images is less than or equal to 734,003,200 bytes [1]
  2. The size of DVD / offline install images is less than or equal to 4,700,000,000 bytes [2]
  3. The size of Workstation Live images is less than or equal to 2,000,000,000 bytes [3]
  4. The size of KDE Live images is less than or equal to 1,400,000,000 bytes [4][5]
  5. The size of Multi-Desktop DVD images is less than or equal to 8,500,000,000 bytes [6] and is intended for DVD-9 Single-Side (SS) Dual-layer (DL) media
  6. The size of Multi-Install DVD installation images is less than or equal to 8,500,000,000 bytes [6] and is intended for DVD-9 Single-Side (SS) Dual-layer (DL) media
