Hi,
I'm a newcomer to working with corosync, and I apologize in advance if this is
a noob problem. I'm trying the API to see whether it would be appropriate to
solving some technical problems with getting multiple nodes of our software to
cooperate. Initially to bootstrap a very non-cluster like cooperation mode,
but later I'll use more capabilities.
When I start the corosync executive, it appears to work properly (now that I've
figured out consensus 1201), but when I start another process that uses the CPG
protocol, I get CS_ERR_TRY_AGAIN. I see no correlated activity in the corosync
log when I do this. Here's the output of the executive:
[...@ohio corosync-1.2.0]$ sudo corosync -f
Mar 29 16:22:42 corosync [MAIN ] Corosync Cluster Engine ('1.2.0'): started
and ready to provide service.

It reaches poll_run() in main - I checked in gdb.
Here's the output of testcpg:
[...@ohio sando]$ cd corosync-1.2.0/test
[...@ohio test]$ sudo ./testcpg
Local node id is 71c0a8c0
Could not join process group, error 6
[...@ohio test]$
A major clue is that corosync will not exit on a SIGINT or SIGTERM, even though
it ought to do so. I need to kill -9 to get the executive to go down and try
again. Is this a known issue in 1.2.0 or something likely correlated with my
problem?
I've had the same behavior on with my hand-compiled corosync 1.2.0 on a Fedora
7 box and with an rpm on Fedora 12 with cluster-glue installed and started.
Thanks to anyone who can help me get started,
Dan Davis
