Hello, There are various xfstests that try to fill up whole partition but they give false positives on file systems with transparent compression because they use compressible test files like input from /dev/zero. Different tests use different ways to generate test file(s) so what would be the preferred way to generate incompressible test files? Use /dev/urandom instead /dev/zero?
