Description Chris Dent 2015-03-19 13:50:25 UTC

(More details on the linked tracker)

When using tooz configured with multiple sentinels to coordinate group membership for the ceilometer central (and other) agents the coordinator fails to update to use a new master redis server.

This is due to lack of retry logic in tooz.

Comment 4 Ami Jeain 2015-03-19 14:17:01 UTC

wasn't this bug targeted for RHOS6 instead of RHOS7?

Comment 5 Chris Dent 2015-03-23 10:48:43 UTC

The upstream fix in tooz that gets failover working has merged: https://git.openstack.org/cgit/openstack/tooz/commit/?id=54d6bb1c94270d2794ecefbcaf3f8832010e3d58

No info yet on when a new tooz release will happen.

Comment 7 Rafael Rosa 2015-04-14 14:04:44 UTC

There was tooz release on April 13th, 0.13.2, it should solve it.

Comment 8 Eoghan Glynn 2015-04-14 14:28:07 UTC

Punted to A4 as discussed on IRC.

*** Bug 1210500 has been marked as a duplicate of this bug. ***

Comment 17 Lon Hohberger 2015-12-18 16:30:19 UTC

Tooz requires 2 other rebases to work.  It's probably safer to fix this with a backport.

Comment 20 nlevinki 2016-07-19 07:40:46 UTC

automation passed
https://rhos-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/RHOS/view/RHOS6/job/rhos-jenkins-rhos-6.0-puddle-rhel-7.2-all-in-one-packstack-nova-flatdhcp-rabbitmq-tempest-git-all/28/
and we verify the fix is in.
since the fix is working on RHOS7 and this was a backport job, I am moving this ticket to verify
