fallocate command fails with 'invalid length value specified' using default swap size

I investigated more.
Size of GitHub action ubuntu image has been reduce:
before:

Filesystem Size Used Avail Use% Mounted on 
/dev/root 84G 53G 31G 64% /

now:

Filesystem Size Used Avail Use% Mounted on 
/dev/root 73G 53G 21G 73% /

Also i played with root-reserve-mb. Size equal 32GB doesn't return error - aquasecurity/trivy#6064

Hello there!
We received the same error.
Our GitHub action broken run
Our configuration

My guess is Github changing its ubuntu-latest version from 20.04 to 22.04 may have something to do with it.

We have seen it work correctly on Ubuntu 22.04.
But i checked successful and broken runs:
image version changed:
successful run:

Runner Image
  Image: ubuntu-22.04
  Version: 20240126.1.0

broken run:

Runner Image
  Image: ubuntu-22.04
  Version: 20240201.1.0

I'm not super familiar with this github action but it seems like the issue is here

sudo touch "${{ inputs.pv-loop-path }}" && sudo fallocate -z -l "${ROOT_LVM_SIZE_BYTES}" "${{ inputs.pv-loop-path }}"

And the value for ${ROOT_LVM_SIZE_BYTES} seems to be incorrect.

And lastly, this is our configuration for using this github action:

- name: Maximize build disk space
  uses: easimon/maximize-build-space@v8
  if: matrix.os == 'ubuntu-latest'
  with:
    root-reserve-mb: 40000
    temp-reserve-mb: 10000
    remove-dotnet: true
    remove-android: true
    remove-haskell: true
    remove-codeql: true

Can confirm reducing root-reserve-mb fixes my issue.
Will close this issue for now.
