Comment 5 for bug 1783374

Can you peek into the subiquity-storage-config yaml and see what the 'size' value of the first partition in raid-0 is?

In your original scenario,

- {id: part-2, type: partition, device: raid-0, size: 32182894592, flag: '', preserve: false}

The max size in Gigabytes is:

32182894592 / (1024 * 1024 * 1024)
29.97265625

One MB smaller

32182894592 - (1 * 1024 * 1024)
32181846016

# convert to gigabytes
32181846016.0 / (1024 * 1024 * 1024)
29.9716796875

29.972Gb
vs
29.971Gb (one MB smaller)
