From c4381dba737d5cb8aad8e1b2e2123b0fcaff1d1a Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Thu, 24 Nov 2011 14:39:10 +0000 Subject: [PATCH] part-disk: Change default alignment of this to 64K (128 sectors). This is the minimum alignment. 1MB would be better. Note that the exact behaviour is not defined in the API. --- daemon/parted.c | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/daemon/parted.c b/daemon/parted.c index dbcae03..0d22948 100644 --- a/daemon/parted.c +++ b/daemon/parted.c @@ -184,15 +184,16 @@ do_part_disk (const char *device, const char *parttype) return -1; } - /* Align all partitions created this way to 64 sectors, and leave - * the last 64 sectors at the end of the disk free.
