From 1c5b0b263f08faa0649bf673a685d93ed9319bef Mon Sep 17 00:00:00 2001 From: "Brian C. Lane" Date: Wed, 4 Feb 2015 16:31:00 -0800 Subject: [PATCH 31/32] tests: Add a test for device-mapper partition sizes (#1188431) device-mapper uses 512b sector units, not device specific sector sizes. This test ensures that the correct partition size is created, no matter what the device's sector size is.
