From a95e28cc35e1d59cedb406914ba437e21bc3e1ea Mon Sep 17 00:00:00 2001 From: Jan Friesse <jfriesse@redhat.com> Date: Thu, 14 Feb 2019 16:05:59 +0100 Subject: [PATCH] quorumtool: Fix exit status codes 1. Use EXIT_SUCCESS and EXIT_FAILURE when possible 2. For -s option return EXIT_SUCCESS when no problem appeared and node is quorate, EXIT_FAILURE if problem appeared and exit code 2 (EXIT_NOT_QUORATE) when no problem appeared but node is not quorate. 3. Document exit codes in the man page Signed-off-by: Jan Friesse <jfriesse@redhat.com> Reviewed-by: Christine Caulfield <ccaulfie@redhat.com> (cherry picked from commit db38e3958c4f88d5d06e8f7c83d6d90334d9fbd2) --- man/corosync-quorumtool.8 | 17 +++++++++++- tools/corosync-quorumtool.c | 53 ++++++++++++++++++++++--------------- 2 files changed, 47 insertions(+), 23 deletions(-) diff --git a/man/corosync-quorumtool.8 b/man/corosync-quorumtool.8 index 915f35ff..2fc4e020 100644 --- a/man/corosync-quorumtool.8 +++ b/man/corosync-quorumtool.8 @@ -31,7 +31,7 @@ .\" * ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF .\" * THE POSSIBILITY OF SUCH DAMAGE. .\" */ -.TH COROSYNC-QUORUMTOOL 8 2012-01-12 +.TH COROSYNC-QUORUMTOOL 8 2019-02-14 .SH NAME corosync-quorumtool \- Set and display quorum settings. .SH SYNOPSIS @@ -89,6 +89,21 @@ show this help text show version and exit .PP * Starred items only work if votequorum is the quorum provider for corosync +.SH EXIT STATUS +corosync-quorumtool may return one of several error codes if it encounters problems. +.TP +0 +No problems occurred (quorate for +.B -s +operation). +.TP +1 +Generic error code. +.TP +2 +Not quorate (returned only for +.B -s +operation). .SH SEE ALSO .BR corosync_overview (8), .BR votequorum_overview (8), diff --git a/tools/corosync-quorumtool.c b/tools/corosync-quorumtool.c index e5d17b16..66ca7de5 100644 --- a/tools/corosync-quorumtool.c +++ b/tools/corosync-quorumtool.c @@ -1,5 +1,5 @@ /* - * Copyright (c) 2009-2014 Red Hat, Inc. + * Copyright (c) 2009-2019 Red Hat, Inc. * * All rights reserved. * @@ -75,6 +75,8 @@ typedef enum { SORT_NODENAME } sorttype_t; +#define EXIT_NOT_QUORATE 2 + /* * global vars */ @@ -238,7 +240,7 @@ static int set_votes(uint32_t nodeid, int votes) votes, nodeid, cs_strerror(err)); } - return err==CS_OK?0:err; + return (err == CS_OK ?
