[pve-devel] corosync problems - need help

[Alexandre DERUMIER]

Also, about the pmxcfs sefgaults,

I have see this messages

Sep 14 09:06:33 kvm1 pmxcfs[65403]: [dcdb] notice: cpg_join retry 62840

Sep 14 10:57:25 kvm11 pmxcfs[13112]: [dcdb] notice: cpg_join retry 65090

with retry around 65000  (16bits)



and 
       int retries = 0;
       result = cpg_join(dfsm->cpg_handle, &dfsm->cpg_group_name); 
        if (result == CPG_ERR_TRY_AGAIN) {
                nanosleep(&tvreq, NULL);
                ++retries;
                if ((retries % 10) == 0)
                        cfs_dom_message(dfsm->log_domain, "cpg_join retry %d", retries);
                goto loop;
        }


could it be related to retries integer type?

My understand is that the faulty node join the mutlicast group, other see it. 

but when others nodes try to talk with him, they have no response ? 



I'm going to do some wireshark network traces today 

I'll also try to update all other nodes to kernel 3.10. (not sure it's related)

This just indicates that corosync does not work as expected.
