are LVM operations required

[sifive-benjamin-morse]

Are the LVM operations required? Would it be possible to just remove the software and skip the LVM step? I only ask because I'm not sure what maximum value I should provide for the root-reserve-mb option. Thanks.

While it would be possible to just remove the software, the LVM setup merges mostly unused temp disk space with the free space of the main disk, adding about 9 GB available space alone. Since these are different disks on the VM, LVM is required to do the merge.

At the moment, skipping this step is not implemented, and I also don't plan it, TBH.

Have you just tried the default for root-reserve-mb of 1024 == 1GB? Does it fail for you?

In my case, the most space is needed on the root, as I'm installing some system packages and building Docker images (well, I can change their location also). In this case, it might also make sense to skip LVM setup.

sorry for the late answer, maybe you already figured that:

the software removal is really mostly a rm -rf on a few directories... you could add that easily directly to your workflow directly and not rely on this action.

For reference: these are the commands used for the packages "known" to the action as remove-*:

          echo "Removing unwanted software... "
          if [[ ${{ inputs.remove-dotnet }} == 'true' ]]; then
            sudo rm -rf /usr/share/dotnet
          fi
          if [[ ${{ inputs.remove-android }} == 'true' ]]; then
            sudo rm -rf /usr/local/lib/android
          fi
          if [[ ${{ inputs.remove-haskell }} == 'true' ]]; then
            sudo rm -rf /opt/ghc
          fi
          if [[ ${{ inputs.remove-codeql }} == 'true' ]]; then
            sudo rm -rf /opt/hostedtoolcache/CodeQL
          fi
          if [[ ${{ inputs.remove-docker-images }} == 'true' ]]; then
            sudo docker image prune --all --force
          fi
          echo "... done"
