2016-10-25Set redis file descriptor limit when run via pacemakerMichele Baldessari1-0/+17
The current redis file descriptor limit is 4096 because of two reasons: - It is run via the redis user - It is not started via systemd which has explicit LimitNOFILE set to 10240 (which matches the default configuration of maximum 10000 clients) Create an /etc/security/limits.d/redis.conf file in order to increase the fd limit value With this change we correctly get the following limits: [root@overcloud-controller-0 ~]# pcs status |grep -A2 redis Master/Slave Set: redis-master [redis] Masters: [ overcloud-controller-2 ] Slaves: [ overcloud-controller-0 overcloud-controller-1 ] [root@overcloud-controller-0 ~]# cat /proc/`pgrep redis`/limits | grep open Max open files 10240 10240 files Previously this limit was set to 4096.

2016-10-12pacemaker: increase timeouts for rabbitmq and redisEmilien Macchi1-0/+1
When we observe the 'stop timeout' values of pacemaker resources: rabbitmq and redis, they are set to 90s. But for all other services, it is set to 200s. The overcloud deployment sometimes fails due to this with the error: Error: Could not complete shutdown of rabbitmq-clone, 1 resources remaining Error performing operation: Timer expired This patch updates the timeout for Redis and RabbitMQ to avoid this error.

2016-08-30Write restart flags to restart services only when necessaryJiri Stransky1-0/+8
Write restart flag file for services managed by Pacemaker into /var/lib/tripleo/pacemaker-restarts directory. The name of the file must match the name of the clone resource defined in pacemaker. The post-puppet restart script will restart each service having a restart flag file and remove those files. This approach focuses on $pacemaker_master only (we don't want to restart the pacemaker services 3 times when we have 3 controllers), so it relies on the assumption that we're making the matching config changes across the pacemaker nodes.

2016-08-08Fix parameters and headers inconsistency in the puppet manifests.Carlos Camacho1-1/+0
As we are staring to manually check overcloud services the first step is to check that the puppet profiles are all aligned. Changes applied: No logic added or removed in this submission. Removed unused parameters. Align header comments structure. All profiles parameters sorted following: "Mandatory params first sorted alphabetically then optional params sorted alphabetically." Note: Following submissions will check pacemaker, cinder, mistral and redis services in the base profiles as some of them has the $pacemaker_master parameter defaulted to true.
