From mboxrd@z Thu Jan 1 00:00:00 1970 From: Fabio M. Di Nitto Date: Thu, 6 Jan 2011 11:38:11 +0100 Subject: [Cluster-devel] [PATCH] Cman: Handle INT and TERM signals correctly Message-ID: <1294310291-6223-1-git-send-email-fdinitto@redhat.com> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit From: Jan Friesse Corosync signal handler (SIGINT and SIGTERM) is replaced by cman one, and this was settting quit_threads to 1. Regular cman shutdown sequence (cman_tool leave) tests if quit_threads is set or not. If so, it refuses continue so it was not possible to cleanly leave cluster. Now SIGINT and SIGTERM are ignored, and (un)intentional kill of corosync is no longer problem.
