From 8f069b41bce79b0c4b6076acd0f3d15df0a232ed Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Fri, 27 Jul 2012 15:08:01 +0100 Subject: [PATCH] dm stripe: remove minimum stripe size There is no technical limitation in device mapper that would prevent the dm-stripe target from using a stripe size smaller than page size. This patch removes the limit and makes stripe volumes portable across architectures with different page size.
