Size Flag Requires Unit Suffix | Generated by AI

Here’s the exact bug. The issue is in commands/volumes.go:

Line 152: size, err := humanize.ParseBytes(sizeStr) Line 194: createVolume.SizeGigaBytes = int64(size / (1 << 30))

When you pass --size 200 (bare number, no unit suffix), here’s what happens:

1. humanize.ParseBytes("200") splits into num=”200” and extra=”” (empty suffix)
2. In bytesSizeTable (line 49): "" maps to Byte (value 1)
3. Result: 200 * 1 = 200 bytes
4. Division: 200 / (1 << 30) = 200 / 1073741824 = 0 GiB (integer truncation)

So --size 200 creates a 0 GiB volume — that’s why the API rejects it.

The fix: The --size flag requires a unit suffix. Use:

doctl compute volume create my-vol --size 200GiB --region sgp1

Valid suffixes from the bytesSizeTable:

• GiB, gib, gi, g → GiB (binary)
• GB, gb → GB (decimal, 1000-based)
• TiB, tib, ti, t → TiB
• TB, tb → TB

The default value on line 53 is "4TiB" — confirming the CLI always expects a suffix. This is different from the AMD Dev Cloud web UI which defaults the unit to GiB.
