Hi James,

This thread is badly fragmented and confusing now, but let's try to
proceed.  It seems corosync ignores its config file.  Maybe you edit a
stray corosync.conf, not the one corosync actually reads (which should
probably be /etc/corosync/corosync.conf).  Please issue the following
command as a regular user, and show us its output (make sure strace is

$ strace -f -eopen /usr/sbin/corosync -p -f

It should reveal the name of the config file.  For example, under a
different version a section of the output looks like this:

open("/dev/shm/qb-corosync-16489-blackbox-header", O_RDWR|O_CREAT|O_TRUNC, 0600) = 3
open("/dev/shm/qb-corosync-16489-blackbox-data", O_RDWR|O_CREAT|O_TRUNC, 0600) = 4
open("/etc/corosync/corosync.conf", O_RDONLY) = 3
open("/etc/localtime", O_RDONLY|O_CLOEXEC) = 3
Process 16490 attached
[pid 16489] open("/var/run/corosync.pid", O_WRONLY|O_CREAT, 0640) = -1 EACCES (Permission denied)

If you can identify the name of the config file, please also post its
path and its full content.
