shewlessHello. I'm following this guide: http://docs.openstack.org/ha-guide/controller-ha-haproxy.html and I'm stuck adding haproxy to the cluster. I'm using crmsh and that section just says "TBA"16:08
shewlessI'm trying to relate the "pcs" instructions but having trouble.16:09
shewlessI can create a primitive like so: crm configure primitive haproxy systemd:haproxy op monitor16:09
shewlessbut when I try and clone it using this command: crm configure primitive clone haproxy-clone haproxy16:10
shewlessI get an error: ERROR: ocf:heartbeat:haproxy-clone: no such resource agent16:11
shewlessany ideas?16:11
shewlessoops. this works better. any idea if it's correct: crm configure clone haproxy-clone haproxy16:13
aspiersshewless: http://crmsh.github.io/man-2.0/#cmdhelp_configure_primitive16:17
aspiersand http://crmsh.github.io/man-2.0/#cmdhelp_configure_clone16:18
shewlessaspiers: thanks. it was a typo on my part16:19

shewlessIn general, if I'm using a pacemaker and haproxy approach defined here: http://docs.openstack.org/ha-guide/controller-ha-haproxy.html do I want haproxy to be running on all servers all the time?17:41
shewlessI'm having a problem where I'm getting an error that haproxy isn't running on the "non active" node17:42
shewlessand I can't start haproxy because it can't bind to the vip..17:42
shewless* haproxy_start_0 on TPC-D15-06 'not running' (7): call=11, status=complete, exitreason='none',     last-rc-change='Thu Aug  4 17:35:31 2016', queued=0ms, exec=2004ms17:42
shewlessI'm not sure if haproxy is supposed to be running on all nodes. And if it is I'm not sure why the second server can't bind to the vip17:43

wNshewless: yes. its supposed to be running on all nodes20:25
wNi ran into that issue before but i cant remember how i fixed it20:26
wNthe idea is that if hte vip falls over, the haproxy instances running on the node that now owns that vip will take over the service20:26
shewlesswN: thanks.. found it.. net.ipv4.ip_nonlocal_bind=120:26
wNexcellent20:27
shewlesswN: while I have you I notice this doc says to add keystone to pacemaker: http://docs.openstack.org/ha-guide/controller-ha-identity.html20:28
shewlessbut keystone is running under apache for me20:28
shewlessso should I add apache to pacemaker instead?20:28
wNshewless: im not certain, but if the service needs to be running on all 3 nodes, i'd add it to pacemaker20:29
wNi havent played around with keystone in apache20:29
*** catintheroof has joined #openstack-ha20:30
shewlessI'd guess apache needs to be running on all 3 nodes regardless of whether keystone is running there20:30
shewlessthe doc seems to fall short there :/20:30
wNi would assume so :)20:38
wNi think pretty much everything runs cloned on all nodes except cinder-volume20:38
wNthe one thing im not sure on is any specific configurations that need to be done in pacemaker for each service, like timeout and stuff like that. i assume your doc covers that20:38
