Re: [libqb] [corosync] shutdown of corosync-notifyd results in shutdown ofpacemaker

[Grüninger, Andreas (LGL Extern)]

Problem solved.
It is an error in libqb.
In Solaris MSG_NOSIGNAL is not defined. In libqb SIGPIPE must be ignored or handled.
A pull request is waiting: https://github.com/asalkeld/libqb/pulls.

Betreff: Re: [corosync] shutdown of corosync-notifyd results in shutdown ofpacemaker

I compiled the the current master of
- libqb
- pacemaker
- corosync
in Solaris 11U7 (gcc 4.5.2) and openSuse 12.2 (gcc 4.7.1).

For the test a configuration with one node and no resources is used.

The start of corosync-notifyd is handled nearly in the same way in linux and solaris.
See below the first two listings. The name of the linux host is "linux-t7bi" and the name of the solaris host is "zd-sol-s1".
In linux the MAIN module logs something. In solaris the same log entries are written from the MON module.

When corosync-notifyd is killed linux handels this gracefully and there are no log entries of pacemaker.
In solaris the event is handled from pacemaker and not from corosync. There are no log entries for corosync. 
Pacemaker shuts down and corosync is still running and healthy. If pacemaker is restarted it connects again to corosync.

How can this be when the same source code is compiled?

More specifically, stopping corosync-notifyd results in all Pacemaker's connections to Corosync being terminated.
