Tests passing:

• note I had to exclude OpenChunkWriter from features as we restrict multi part uploads for files smaller than 100MBs, some tests were failling due to this restriction

You've got this in your code which should be all you need. Where are the tests excluded - I don't see that?

                ChunkedUpload: fstests.ChunkedUploadConfig{
			MinChunkSize:       100 * fs.Mebi,
			NeedMultipleChunks: true,
		},

I had two failling tests TestMultithreadCopy/upload=true,size=62914561,streams=2 and TestIntegration/FsMkdir/FsOpenChunkWriter. One where it tests a streamed file which we reject due to unknown size and the other which we reject due to it's small size. The only way I found to skip these tests was by setting f.features.OpenChunkWriter = nil manually right after .fill() see here

Ah, if you do that then you disable the feature and this pr is pointless!

It sounds like the first failure is a bug in the tests.

The second can be fixed by Skip the test if features.PutStream ==0

Do you want to try to fix the integration tests?

Oh, then definetely let me remove that line and ensure tests pass
