<body class='hmmessage'><div dir='ltr'>Hi list,<div><br></div><div>I have a situation where I would like to run multiple instances of Corosync, each 'group' on a number of hosts, with each instance providing HA for a dedicated service, thus allowing for benefits around change control, risk management, service/environment separation and the like. The hosts in question run nothing but Docker containers, with the Corosync (+Pacemaker) containers using host mode networking.</div><div><br></div><div>Whilst I can change the UDPU port used by Corosync, a second instance (container) fails with a socket error. Here's the relevant logs:</div><div><br></div><div><div>Jan 06 13:47:55 [19] rancher-one corosync info [QB ] server name: cmap</div><div>Jan 06 13:47:55 [19] rancher-one corosync error [QB ] Could not bind AF_UNIX (): Address already in use (98)</div><div>Jan 06 13:47:55 [19] rancher-one corosync info [QB ] withdrawing server sockets</div><div>Jan 06 13:47:55 [19] rancher-one corosync error [MAIN ] Can't initialize IPC</div><div>Jan 06 13:47:55 [19] rancher-one corosync error [SERV ] Service engine 'corosync_cmap' failed to load for reason 'qb_ipcs_run error'</div><div>Jan 06 13:47:55 [19] rancher-one corosync error [MAIN ] Corosync Cluster Engine exiting with status 20 at service.c:356.</div><div><br></div><div>Can this be overcome? Is there a way to specify a different socket?</div><div><br></div><div>Many thanks in advance.</div><br><div>Kind regards,</div><div><br></div>Steven Iveson<div>steve@iveson.eu</div><div><a href="https://twitter.com/sjiveson" target="_blank">@sjiveson</a></div><div><div>Blogs: <a href="https://packetpushers.net/author/siveson" target="_blank">https://packetpushers.net/author/siveson/</a></div><div>Books: <a href="http://www.amazon.com/Steven-Iveson/e/B00BIR04XM/" target="_blank">http://www.amazon.com/Steven-Iveson/e/B00BIR04XM/</a></div></div><div>07734 778 184</div></div> </div></body>
