2017-01-25Composable HAMichele Baldessari1-1/+19
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 Baldessari1-1/+7
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
2016-11-29pacemaker: create Mysql_user once Galera is ready (puppet4)Emilien Macchi1-1/+2
Puppet 4 ordering make things more strict in catalog, which is good. Resources have to be orchestrated or Puppet will take them in the order they are found in catalog. This patch makes sure we create MySQL users only when Galera is actually ready. Closes-Bug: #1645787 Change-Id: I536a1a128c3a7eca49bcc4f34a1307bcd60b029e
2016-10-13pacemaker/mysql: wait step 2 to remove default accountsEmilien Macchi1-1/+11
remove_default_accounts is a mysql::server parameter that, set to True, will execute some MySQL commands to cleanup MySQL defaults accounts created by packaging. In order to successfully run the commands, we need MySQL up and running, which is not the case at step 1 but at step 2. This patch make sure we run the commands at step 2 on pacemaker master only. No change for scenarios without Pacemaker. Change-Id: Ifad3cb40fd958d7ea606b9cd2ba4c8ec22a8e94e Closes-Bug: #1633113
2016-10-05Enable usage of "short names" for Galera clusterJuan Antonio Osorio Robles1-1/+6
We're not able to use FQDNs yet, so to work around this, we give precedence to a "short name" list we'll get from t-h-t. Change-Id: I4ef7786474c229d5212a0deb2ca02ee992b030d8 Related-Bug: #1628521

2016-09-27Move db syncs into mysql base roleDan Prince1-0/+5
This patch moves the various DB syncs into the MySQL role. Database creation needs to occur on the MySQL server to avoid permission issues. This patch also moves database creation to step 2 so we can guarantee that all per-service databases exist at this time. This avoids complex ordering needed during step 3 where services, on different hosts, can run their own db sync's in a distributed fashion.

2016-09-24Make mysql bind-address configurableJuan Antonio Osorio Robles1-2/+7
It used to be hardcoded that the bind-address was always coming from the $::hostname fact. This is wrong, as it disregards where we have configured the mysql address. This commit actually makes it configurable, so we'll be able to set it via hieradata. On the other hand, we use the hiera key that we already set 'mysql_bind_host' as a default; if, for some reason, that's unavailable then we fall back to $::hostname.

2016-09-16mysql: never add brackets to mysql_bind_hostEmilien Macchi1-1/+1
Don't add brackets on mysql_bind_host parameter in Galera config. Having brackets from this parameter works with old version of Galera but not newest one. So let's remove them at all, so we can safely upgrade Galera in RDO. Change-Id: Ic904d4efda162f18ec8dffb91c2f383f54361f41 Closes-Bug: #1622755

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.

Prepare the pacemaker mysql manifest that galera_node_names will be an array. Stay backwards compatible to handle comma-delimited-string too and avoid a chicken-and-egg patch problem between t-h-t and puppet-tripleo.

2016-08-17Configure galera-monitor on all controller nodesMichele Baldessari1-1/+1
When we implemented the galera composable role we accidentally moved the xinetd.d monitor service on the bootstrap node only. This meant that haproxy believed that galera was down on the non-bootstrap nodes. A shutdown of the bootstrap node meant that galera was effectively down because haproxy would refuse to redirect the traffic to the non-bootstrap node. Fix this by creating the /etc/xinetd.d/galera-monitor on all controller nodes. Change-Id: Ib5a06b3abbc32182476c2b0c81eb77a12821ad6b

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.

2016-07-27Remove global openstack-core resourceGiulio Fidente1-11/+0
The openstack-core resource is not needed by the NG Pacemaker architecture. It was moved into an isolated role by [1] so that it could optionally be enabled when wanting the older architecture. This submission removes the old openstack-core global resource. 1. I74a62973146c0261385ecf5fd3d06db51e079caa Change-Id: I16a786ce167c57848551c7245f4344c382c55b3d
2016-07-22use parameter to lookup the step instead of hiera againEmilien Macchi1-3/+3
In some profiles, we were looking up the $step by using Hiera again, while we already do it in the parameter definition. When using this class outside THT, it will fail but with this patch, we could use just set the $step parameter and the rest of the manifest will work.
