Subject [jira] [Commented] (CLOUDSTACK-6975) Service monitoring starts dnsmasq on backup router when using redundant VRs
Date Mon, 23 May 2016 13:39:12 GMT


ASF GitHub Bot commented on CLOUDSTACK-6975:

Github user dsclose commented on the pull request:
    @luhaijiao I reverted to a vanilla Cloudstack 4.8.0 ISO. The cloud-passwd-srvr service
failed to start. The following appears in /var/log/messages on the router:
    `Password server failed with error code 1. Restarting it...`
    The same was true with this patch as well. In both cases, manually restarting the service
(as the root user) was successful. I think we should treat the password server issue as separate
and raise that elsewhere.
    I'll kick off the tests again here.

> When using a network offering with redundant routers the default setting of EnableServiceMonitoring
enables monit on the routers.
> "network.router.EnableServiceMonitoring	service monitoring in router enable/disable option,
default true	false"
> This causes monit to run dnsmasq on both the Master and Backup router. When the backup
router assigns dhcp to clients, password and userdata retrieval from that node fails since
the services are not running on the backup router.
