2017-01-25Composable HAMichele Baldessari1-1/+21
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 Baldessari1-2/+2
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
2017-01-11Set ceph key when using manila ceph backendJan Provaznik1-1/+36
Manila ceph driver reads ceph's client configuration (keyring is the most important) from ceph.conf file (or any other file set by cephfs_conf_path). ceph.conf should be updated with keyring location. If ceph is deployed by tripleo then also manila ceph key is added into ceph and ceph filesystem is created.

2017-01-02Don't include api/scheduler manifests on manila share service set upJan Provaznik1-2/+0
Manila pacemaker manifest (which sets manila share service only) includes also manila api and scheduler manifests. There is no reason for this. Also it causes that on whichever node manila share service runs also manila api and scheduler services are started. Change-Id: Ia1b39ef36c5bc34813cd6430b69ad9b698acc3cf Closes-Bug: #1653500
2016-10-07Use Heat role *_enabled hiera to check Manila backendsGiulio Fidente1-8/+20
Aligns the way how we check for enabled backends in pacemaker/manila.pp with what we did in base/manila/api.pp with [1]. The benefit is that we don't need to emit from the templates custom hiera. 1. I86ba8b9d5872c0f1a94e74215e97b796ad129bfb Change-Id: I04e28a95e8d69a24cd3df109bf1802bfcbd941db
2016-10-03Fix the timeout for pacemaker systemd resourcesMichele Baldessari1-1/+3
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
2016-09-23Move inclusion of ::manila::db::mysql in manila/api profileGiulio Fidente1-4/+4
In puppet-manila it is the api service performing db sync, not scheduler. This change moves ::manila::db::mysql (which creates the empty database and users) in the tripleo manila/api profile. Also moves rabbit config into a general manila base profile as that would be needed by the scheduler service as well. Change-Id: I2b537f735b8d1be8f39e8c274be3872b193c1014
2016-09-20Fixup manila-cephfs native backend defaultsmarios1-41/+7
The puppet-tripleo side for manila-cephfs landed without specifying defaults for all class params [1] so when cephfs isn't enabled e.g. only generic, then you will get errors for those params. See review comments at [2] for reports of this. This will fixup the manila-cephfs puppet-tripleo side to be more in line with the tidy up adding netapp at [3]. The config is all moved tripleo-heat-templates side. The tht review for this is at https://review.openstack.org/#/c/358525/ and that will now depend on this review.

2016-09-16Add manila-netapp backend to manila class and tidy up genericmarios1-81/+41
This adds support for the manila-netapp backend. The backend specific config is set tht side. So this change also tidies up the manila generic config, which is unnecessarily being duplicated here ( see https://review.openstack.org/#/c/354019/ ) Change-Id: Ic6f8e8d27ca20b9badddea5d16550aa18bff8418
2016-08-30Write restart flags to restart services only when necessaryJiri Stransky1-0/+6
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 Camacho1-45/+44
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.
