From 876eb1b0cc2b04927739cba10e4e73e8b990d65e Mon Sep 17 00:00:00 2001 From: Teruaki Ishizaki Date: Fri, 13 Feb 2015 18:20:53 +0900 Subject: sheepdog: selectable object size support Previously, qemu block driver of sheepdog used hard-coded VDI object size. This patch enables users to handle VDI object size. When you start qemu, you don't need to specify additional command option. But when you create the VDI which doesn't have default object size with qemu-img command, you specify object_size option. If you want to create a VDI of 8MB object size, you need to specify following command option. # qemu-img create -o object_size=8M sheepdog:test1 100M In addition, when you don't specify qemu-img command option, a default value of sheepdog cluster is used for creating VDI. # qemu-img create sheepdog:test2 100M Signed-off-by: Teruaki Ishizaki Acked-by: Hitoshi Mitake Signed-off-by: Kevin Wolf --- include/block/block_int.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/block/block_int.h b/include/block/block_int.h index b340e7e..9f7b5bd 100644 --- a/include/block/block_int.h +++ b/include/block/block_int.h @@ -56,6 +56,7 @@ #define BLOCK_OPT_ADAPTER_TYPE "adapter_type" #define BLOCK_OPT_REDUNDANCY "redundancy" #define BLOCK_OPT_NOCOW "nocow" +#define BLOCK_OPT_OBJECT_SIZE "object_size" #define BLOCK_PROBE_BUF_SIZE 512 -- cgit v1.1
