2017-07-12Leverage kolla config_files to copy config into containersMartin André2-9/+4
This solves a problem with bind-mounts when the containers are holding files descriptors open. At the same time this makes the template more robust to puppet changes since new config files will be available in the containers without needing to update the templates.

2017-06-14Ensure hiera step value is an integerSteve Baker4-4/+4
The step is typically set with the hieradata setting an integer value: {"step": 1} However it would be useful for the value to be a string so that substitutions are possible, for example: {"step": "%{::step}"} This change ensures the step parameter defaults to an integer by calling Integer(hiera('step')) This change was made by manually removing the undef defaults from fluentd.pp, uchiwa.pp, and sensu.pp then bulk updating with: find ./ -type f -print0 |xargs -0 sed -i "s/= hiera('step')/= Integer(hiera('step'))/" Change-Id: I8a47ca53a7dea8391103abcb8960a97036a6f5b3

2017-01-25Composable HAMichele Baldessari2-2/+42
This commit implements composable HA for the pacemaker profiles. - Everytime a pacemaker resource gets included on a node, that node will add a node cluster property with the name of the resource (e.g. galera-role=true) - Add a location rule constraint to force running the resource only on the nodes that have that property - We also make sure that any pacemaker resource/property creation has a predefined number of tries (20 by default). The reason for this is that within composable HA, it might be possible to get "older CIB" errors when another node changed the CIB while we were doing an operation on it. Simply retrying fixes this. - Also make sure that we use the newly introduced pacemaker::constraint::order class instead of the older pacemaker::constraint::base class. The former uses the push_cib() function and hence behaves correctly in case multiple nodes try to modify the CIB at the same time.

2017-01-18Do not depend on bootstrap_nodeid for any pacemaker profileMichele Baldessari2-4/+4
When we create a pacemaker resource it must happen from a single node. If it happens from multiple nodes an immediate error will be returned by pcs. For the pacemaker roles we enforce this by leveraging the recently introduced <SERVICE_NAME_bootstrap_short_node_name> which gives us the first hostname per-service, regardless of the role. (introduced via I03e8685f939e8ae1fcd8b16883b559615042505d) With this approach if a pacemaker service belongs to two different roles (say role Controller on node A and role galera on node B), it will only create the resource from one of the two and not both (which would return an error). Only setting Partial-Bug for this one, because it addresses the issue from the pacemaker resource creation POV (which is always affected). But the issue itself is a race that we're theoretically affected by since the composable roles work landed. While I have tried to fix the more general case in previous attempts, I think it is best if we start a discussion on how to fix it, because each approach has a bunch of potential drawbacks and is quite invasive on how we do things. A discussion slot for this has been proposed for the Atlanta PTG. Change-Id: I662398cab60d523d204b57a5674ca8f5c0f2e68a Partial-Bug: #1615983
2016-10-25Remove unused pacemaker profilesMichele Baldessari2-153/+0
With the landing of HA NG in Newton we can actually remove the pacemaker profiles we do not need. The only ones that are being used in one form or the other are: $ grep -ir services\/pacemaker environments | awk '{ print $3 }' | sort | uniq ../puppet/services/pacemaker/cinder-backup.yaml ../puppet/services/pacemaker/cinder-volume.yaml ../puppet/services/pacemaker/database/mysql.yaml ../puppet/services/pacemaker/database/redis.yaml ../puppet/services/pacemaker/haproxy.yaml ../puppet/services/pacemaker/manila-share.yaml ../puppet/services/pacemaker/rabbitmq.yaml ../puppet/services/pacemaker.yaml The only exception is profile/pacemaker/database/mongodbvalidator because it is included by profile/base/database/mongodb.pp Change-Id: I80c8559bb2d915385bcc20ae71fe144ddd6591c1
2016-10-03Fix the timeout for pacemaker systemd resourcesMichele Baldessari4-2/+8
Back in the Mitaka cycle via the change If6b43982c958f63bc78ad997400bf1279c23df7e we made sure that the default start and stop timeouts for pacemaker systemd resources is 200s (>= twice the default 90s DefaultTimeoutStopSec in systemd). We did this change by setting puppet resource defaults for the Pacemaker::Resource::Service class: Pacemaker::Resource::Service { op_params => 'start timeout=200s stop timeout=200s', } The problem is that after the composable services rework, this does not work anymore and the pacemaker systemd resources that still exist do not have these timeouts set. We want to move away from resource defaults for this because its results are dependent on the inclusion order which in tripleo is not guaranteed any longer (https://docs.puppet.com/puppet/latest/reference/lang_scope.html#scope-lookup-rules) The only services affected in Newton are: cinder-volume, cinder-backup, manila-share, haproxy. I preferred fixing all the pacemaker resources because it seems the cleanest and most logical commit. Change-Id: If89a95706514e536a7a2949871a0002c79b6046e Closes-Bug: #1629366
2016-08-30Write restart flags to restart services only when necessaryJiri Stransky2-0/+12
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 Camacho3-3/+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.

2016-08-01Next generation HA architecture workMichele Baldessari2-17/+17
This change moves the cinder-volume/cinder-scheduler constraints in the cinder-scheduler profile as these can't be applied by the cinder-volume service when cinder-scheduler isn't managed by Pacemaker.

2016-07-18Make ::tripleo::profile::base classes work with multiple nodesMichele Baldessari1-3/+1
In the Next Generation HA architecture a number of active/active services will be run via systemd. In order for this to work we need to make sure that the sync_db operation only takes place on the bootstrap node, just like it is done today for the pacemaker profiles. We do this by removing sync_db as a parameter and instead set it to true or false depending if the hostname matches the bootstrap_node as it is done today in the pacemaker role. Note that we call hiera('bootstrap_nodeid', undef) because if a profile is included on a non controller node that variable will be undefined. The following testing was done: - HA puppet-pacemaker.yaml scenario with three computes - NonHA with one controller - NonHA with three controllers Fixes-Bug: 1600149 Co-Author: cmsj@tenshu.net Change-Id: I04a7b9e3c18627ea512000a34357acb7f27d6e0e Implements: blueprint ha-lightweight-architecture
