Description of problem: If I enable votequorum logging in corosync.conf as below, the log messages come tagged as [QUORUM] instead of [VOTEQ] logging { to_syslog: yes logger_subsys { subsys: VOTEQ debug: on } } Version-Release number of selected component (if applicable): 7.0 How reproducible: Every time Steps to Reproduce: 1. Add logging stanza to corosync.conf 2. Enable debug logging in rsyslog.conf 3. read syslog file Actual results: votequorum log messages come out prefixed with [QUORUM] Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] got nodeinfo message from cluster node 4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] nodeinfo message[0]: votes: 0, expected: 0 flags: 0 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] total_votes=4, expected_votes=4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] node 1 state=1, votes=1, expected=4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] node 2 state=1, votes=1, expected=4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] node 3 state=1, votes=1, expected=4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] node 4 state=1, votes=1, expected=4 Oct 10 16:45:43 localhost corosync[9666]: [QUORUM] lowest node id: 1 us: 2 Expected results: Log messages should match the subsystem requested in corosync.conf. In this case [VOTEQ ] Additional info:
I have narrowed this down to what I think is a libqb bug (or maybe a feature). it seems the file matching algorithm in log.c function _cs_matches_filter_ doesn't distinguish between votequorum.c and quorum.c because the latter is contained in the former. If there are some quorum.c filters defined AFTER votequorum.c filters then they get applied and the tags get set to 1 [QUORUM] instead of 7 [VOTEQ ] Ping me on IRC if you need more information.
