From fca23f0ad211e4debf80796a65165d0eea146424 Mon Sep 17 00:00:00 2001 From: Liu Yuan Date: Mon, 18 Mar 2013 14:27:55 +0800 Subject: sheepdog: show error message for halt status Sheepdog (neither quorum nor unsafe mode) will refuse to serve IO requests when number of alive nodes is less than that of copies specified by users. This will return 0x19 to QEMU client which currently doesn't recognize it. This patch adds an error description when QEMU client receives it, other than plainly printing 'Invalid error code' Cc: MORITA Kazutaka Cc: Kevin Wolf Cc: Stefan Hajnoczi Signed-off-by: Liu Yuan Reviewed-by: Stefan Hajnoczi Reviewed-by: MORITA Kazutaka Signed-off-by: Kevin Wolf --- block/sheepdog.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'block') diff --git a/block/sheepdog.c b/block/sheepdog.c index 4245328..54d3e53 100644 --- a/block/sheepdog.c +++ b/block/sheepdog.c @@ -65,6 +65,7 @@ #define SD_RES_WAIT_FOR_FORMAT 0x16 /* Waiting for a format operation */ #define SD_RES_WAIT_FOR_JOIN 0x17 /* Waiting for other nodes joining */ #define SD_RES_JOIN_FAILED 0x18 /* Target node had failed to join sheepdog */ +#define SD_RES_HALT 0x19 /* Sheepdog is stopped serving IO request */ /* * Object ID rules @@ -344,6 +345,7 @@ static const char * sd_strerror(int err) {SD_RES_WAIT_FOR_FORMAT, "Sheepdog is waiting for a format operation"}, {SD_RES_WAIT_FOR_JOIN, "Sheepdog is waiting for other nodes joining"}, {SD_RES_JOIN_FAILED, "Target node had failed to join sheepdog"}, + {SD_RES_HALT, "Sheepdog is stopped serving IO request"}, }; for (i = 0; i < ARRAY_SIZE(errors); ++i) { -- cgit v1.1
