[Maria-discuss] Weighted Quorum for Three Nodes
by Tom Worster 27 Dec '15

27 Dec '15

In the Galera docs <http://galeracluster.com/documentation-webpages/weightedquorum.html#weighte d-quorum-for-three-nodes> I read > When configuring quorum weights for three nodes, use the following pattern: > node1: pc.weight = 2 > node2: pc.weight = 1 > node3: pc.weight = 0 > Under this pattern, killing node2 and node3 simultaneously preserves the > Primary Component > <http://galeracluster.com/documentation-webpages/glossary.html#term-primary-… > mponent> on node1. Killing node1 causes node2 and node3 to become > non-primary components. The wording makes it sound as though this is a general recommendation. But, iiuc, this cluster of 3 nodes has a single point of failure: node1. How is this desirable? Tom

Re: [Maria-discuss] enforce_storage_engine galera cluster
by Federico Razzoli 22 Dec '15

I didn't suggest to use MyISAM :) Now I understand your purpose. If you use MaxScale, you can use a filter and replace MyISAM with InnoDB. Something like: /engine( )*=( *)myisam/i And you can use similar regexps for each storage engine. The filter that you need is this one: https://github.com/mariadb-corporation/MaxScale/blob/master/Documentation/F… Hope that this helps.

Anyway, this bug seems to break our plans, so we should report the bug and find another way in the meanwhile....in addition, MyISAM replication is described as experimental and we don't want to use it in such early development phase.

[Maria-discuss] enforce_storage_engine galera cluster
by Michele Tota 22 Dec '15

22 Dec '15

Hi, we have a problem using enforce_storage_engine variable set to InnoDB. We have three servers in cluster (multi masters). When we issue create table with engine=MyISAM the engine is correctly enforced to InnoDB only on the node we are connected to. On the other nodes the replicated table is created as MyISAM. This is our servers configuration, the same on all nodes: ... enforce_storage_engine='InnoDB' wsrep_on=ON sql_mode='' ... How can we enforce InnoDB on all nodes? Thanks, Michele

[Maria-discuss] Announcing release for MariaDB 5.5 and 10.0 on CentOS Linux 6 and 7 x86_64 SCL
by Honza Horak 21 Dec '15

21 Dec '15

I am pleased to announce the immediate availability of versions 5.5 and 10.0 of the MariaDB server on CentOS Linux 6 and 7 x86_64, delivered via a Software Collection (SCL) built by the SCLo Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo) QuickStart ---------- You can get started in three easy steps (example of MariaDB 10.0): $ sudo yum install centos-release-scl $ sudo yum install rh-mariadb100 $ scl enable rh-mariadb100 bash At this point you should be able to use MariaDB just as a normal application. An examples of commands run might be: $ service rh-mariadb100-mariadb start $ mysql In order to view the individual components included in this collection, including additional subpackages plugins, you can run: $ sudo yum list rh-mariadb100\* About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The collection rh-mariadb100 delivers version 10.0 of the MariaDB server (with daemon called rh-mariadb100-mariadb) and related client tools. The collection mariadb55 delivers version 5.5 of the MariaDB server (with daemon called mariadb55-mariadb) and related client tools. Both the collections include no client library libmysqlclient.so and client applications are advised to use the client library available in mysql-libs package from base system. For more on the MariaDB, see https://mariadb.org. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the MariaDB collections being released here, we also build and deliver other databases, web servers, and language stacks including multiple versions of MySQL, PostgreSQL, MongoDB Apache HTTP Server, NodeJS, Ruby, Python and others. Software Collections SIG release was announced at https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html You can learn more about Software Collections concepts at: http://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto get involved and help with the effort. We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: https://www.centos.org/community/calendar) for an informal open forum open to anyone who might have comments, concerns or wants to get started with SCL's in CentOS. Enjoy! Honza SCLo SIG member

Hello, A new question has been asked in "Slow Query Log" by yu.d.sun_32615. Please answer it at http://mariadb.com/kb/en/slow-query-log-and-long_query_time/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- In my understanding if we enable slow query log, MySQL will capture all SQL statements that take more than long_query_time seconds to execute into the log.

[Maria-discuss] max key length in import
by Warren H. Prince 17 Dec '15

17 Dec '15

I’m considering moving from MySql to MariaDB so I did a dump today and attempted an import. It failed with the “Specified key was too long; max key length is 767 bytes” error. I dealt with this in MySql and knew to change file format to Barracuda. I zapped the partial import, did a fresh mysql_install_db, restarted the service and tried again to no avail. To confirm my settings immediately after the failure: MariaDB [(none)]> SHOW VARIABLES LIKE 'innodb_file_%'; +--------------------------+-----------+ | Variable_name | Value | +--------------------------+-----------+ | innodb_file_format | Barracuda | | innodb_file_format_check | ON | | innodb_file_format_max | Barracuda | | innodb_file_per_table | ON | +--------------------------+—————+ Does anyone have any suggestions? The dump is 795M compressed so it’s difficult to find the exact place where the problem is (I used zcat for the import). My distribution is: 10.0.22-MariaDB running on Ubuntu 15.04 Thanks in advance.

[Maria-discuss] Replication variables in my.cnf seem ignored if master connection does not exist
by Игорь Пашев 16 Dec '15

16 Dec '15

MariaDB 10.0.22 I saw weird things a couple of times: I start clean MariaDB with theses options in the configuration file: foo.replicate_wild_do_table = foo_live.% foo.replicate_ignore_table = foo_live.schema_updates Then I execute RESET SLAVE "foo" ALL just to be sure there is no such connection. Then I import the dump of master, and set master options like host, user, password, etc. Then I execute START SLAVE "foo" Then SHOW SLAVE "foo" reveals empty 'Replicate_Wild_Do_Table' and 'Replicate_Ignore_Table'. (And replication shortly breaks, because foo_live.schema_updates wasn't imported). I can fix this by restarting MariaDB. I'd expect the foo.replicate_* options are taking effect anytime. As a work-around I'd set those options dynamically after dump is imported. (I will fill MDEV in case it is confirmed as a bug)

[Maria-discuss] MariaDB Performance and Diagnostic Tools
by FERRETTI, ANDY 15 Dec '15

15 Dec '15

I'm looking for recommendations on MariaDB Performance Analysis tools. 1. I try MySQL workbench, but much of the capability is disabled. I get an error when I click on the Dashboard "This feature requires MySQL version 5.6.6 or newer". 2. I'm wondering if there are some good scripts to help identify key performance metrics from the performance_schema. I'd like to see a capability similar to an Oracle AWR report. I spent a fair amount of time doing google searches, and found some information on the performance_schema: https://php-built.com/enabling-performance-monitoring-for-mariadb-and-mysql/ , but I really think there should be something better.

[Maria-discuss] Galera Cluster: Cluster Blocked, when one node down?
by Benoit Panizzon 14 Dec '15

14 Dec '15

Hello We use MariaDB Galera Cluster for our email service platform. We decided to use Galera to create a high availability platform. After a year of operation, we start to relaize, that somehow Galera Failures seem to be the most common cause for outages we had in the past. So I wonder if others operating galera clusters also observe this situation: All our services using DB connections use a DNS round-robin name, to connect to one of our three galera instances. While testing this setup, we usualy killed one instance, or disconnected the node from the network to simulate an outage. In this situation, this works as expected. The client connect to the two remaining nodes, no service outage. When the node is re-started it is being re-synced quickly and service with three nodes is restored. Now we experienced a few galera cluster fails, which seem to happen this way: One of the nodes is getting a lot of load. DDOS Attacks, Memory Leaks or similar, which just renders the whole physical machine laggy for a short time. So the affected MariaDB node is being thrown out of the cluster by the two other nodes, probably for not syncing fast enough anymore. But as the node is not 'down' completely, it still accepts connections from the DB clients, but does not reply to them and seems to remain in a 'db locked' situation. Strangely this then also affects the two remaining nodes, who also go into 'locked' mode and do not reply to queries on the time expected by the application anymore. Of course this then causes more DB clients (IMAP, SMTP-Auth, etc) to spawn and to create DB connections worsening the whole situation. The situation seemingly can only be resolved by shuting down the MariaDB node that got thrown out of the cluster. Then the situations normalizes with the two remaining nodes and the third one can be restarted. Is this expected behaviour? Is there a way to tell a MariaDB node that got excluded from the cluster to shut himself down completely so it does NOT accept any more connections from clients, blocking the whole service?

[Maria-discuss] Queries Not Completing After Backup
by Brad Jorgensen 11 Dec '15

11 Dec '15

We have a three node (db1, db2, db3) galera cluster with MariaDB 10.0.22 on CentOS 6.7. A couple days ago I upgraded to 10.1.9. Xtrabackup (2.3.2) is run every night on each node at 1am, 2am, and 3am respectively. Before the backup starts, the node is desynced. The first night after upgrading to 10.1.9, the problem began. All connections were going to db1 until the backup started when db1 was removed from the routing pool and new connections began going to db2. At that time there was little traffic aside from the backup; much of it is probably monitoring queries. Our monitoring shows that running threads went from about 2 just before the backup finished around 1:32am to about 150 just after. At the same time, the running threads on db2 went from 1 to 10. After the backup completed, all new connections were going to db1 again. The running threads on db1 continued to slowly grow until the queries that are stuck took up all of the server processes on our application servers and we were alerted around 3:50am. I checked the process list and almost all of the queries were in the "query end" state and I think they were all write queries. I tried to kill most of them but they just stayed in the same state. I restarted db2 to try to kick the cluster without losing data. I had to force the shutdown since three threads never ended after about 10 minutes of waiting. The running threads on db1 returned to normal. db2 had do do a full SST which took until 6:05 to complete. At that time, the running processes on db1 began to increase again. When db2 was back up I downgraded to 10.1.22 and rejoined it to the cluster. I tried to restart db1, but it needed a full SST so I left it down. A bit later I took down db3 to downgrade it, too at that went fine. The cluster was fine through the day during normal business operation. The next night only db2 and db3 were up and were running 10.0.22. What appears to be the same problem started at 3:31am, when xtrabackup paused galera ("Provider paused at 8c53b634-9514-11e4-b8bd-dab05673fb36:875650526") on db3 for the backup. At that time the running threads on db2 shot up and slowly increased until I shut it down at 6:28. I had to kill it again due to three threads on ending. db3 showed nothing unusual in the logs. I got the innodb engine status from db2 three times a few minutes apart before I restarted; they are attached. Additionally, I attached an excerpt from the logs on db2 and db3 during the second incident and the my.cnf from one of the servers, it's basically the same for the others. I'm working on getting a clean set of logs from the first incident, but from what I initially saw, they are basically the same as the second set of logs. I'm ready if the problem arises again and I'll try to get more information including SHOW GLOBAL STATUS. Our environment hasn't changed for at least a month and the issue first appeared after upgrading to 10.1.9, but since it didn't go away after downgrading, I'm not sure where the issue is. I found a few mentions of what might be the same problem: http://marialog.archivist.info/2015-04-03.txt https://bugs.launchpad.net/percona-xtradb-cluster/+bug/1149755

[Maria-discuss] Most reliable SST (or IST ?) method for MariaDB Cluster
by Bertrand Caplet 05 Dec '15

05 Dec '15

Hi all, I'm using MariaDB Cluster with 3 servers and I often have split brain because of network. When a network split brain happen, only one node is disconnected. What is for you the best choice for SST or maybe IST method for this configuration ? (N.B.: I already tried rsync method but i'm not really satisfied with it). I have another question, I tried xtrabackup-v2 but it seems this method can't be use for bootstrapping while database is on. Does xtrabackup method can do this ?

[Maria-discuss] MariaDB and Galera Support from Redhat (instead of MariaDB corp)
by Lukas Lehner 25 Nov '15

25 Nov '15

Hi we run DBaaS (Galera Cluster) with growing customer base. We also offer MongoDB, where we have commercial support from MongoDB (we can recommend it). MariaDB is included in RHEL, so Red Hat offers support. We anyway pay for Redhat support. So it means we don't need to buy support from MariaDB? Does Redhat employs MariaDB developers and have DBA/Expert know how? Lukas

[Maria-discuss] Creating MySQL .MYD, .MYI and .frm tables in Maria
by Carl Whalley 25 Nov '15

25 Nov '15

This is the final stage from my thread regarding a botched F22->23 upgrade which hosed bacula. I have been on to bacula support and they claim not to support Maria. Well, "not support" isn't right, just "not explicitly tested" - I know everything was ok under F22/Maria as I have another server to upgrade which runs fine now with this setup. It seems the MySQL tables were created when bacula was installed several iterations of Fedora ago, and at that time they were of the .MYD, .MYI style. Each time fedora was updated, these were carried forwards - possibly through the swap from when MySQL was native to it becoming Maria, as we see now. That's why all the existing ones are in the form with the extensions I mentioned. So, I'm now in a situation where it seems I have to create one last table ("Snapshot") and am having trouble because it somehow has been created but not in the .MYD, MYI style. The create table command is supplied already for me to enter - how can I remove the phantom one and create it again in the format the rest of the tables are in please?

[Maria-discuss] Problems installing MariaDB 10.1 on LEAP.
by Peter Laursen 23 Nov '15

23 Nov '15

I am facing problems installing MariaDB 10.1 on OpenSuSE LEAP (42.1) from the MariaDB repository for OpenSUSE 13. Even though built on/for SuSE 13.1 it worked fine on SuSE 13.2 as well. But not on LEAP: Please see attached screenshot from YaST (GUI) installer environment. I think that tells everything. 10.1 packages displayed here are from MariaDB repo (that registers with no problem with YaST/zypper, BTW). 10.0 and other packages displayed are from official SuSE repo. The 10.0 server from SuSE repo works fine, but I prefer 10.1 on this new VM. I am not interested in a 'hack-solution'. I can wait for a proper solution. But something (the memory allocation manager, seemingly) seems changed in OpenSuSE between-from 13.2 and LEAP creating a dependency problem with **MariaDB_from_MariaDB**. Is a new repo required to support OpenSUSE LEAP? @Daniel? -- Peter -- Webyog

[Maria-discuss] per session query rewrite?
by James Leu 21 Nov '15

21 Nov '15

Hello, I've recently discovered the QueryRewrite plugin. I was wondering if there was any thought, or active work on making the rewrite rules associated with a connection/session. If there is not any active work on this, would the community find this useful? If so I would be willing to start development towards it. Any guidance would be greatly appreciated. -- James R.

[Maria-discuss] Connect Engine with ODBC
by Bruce Carlson 19 Nov '15

19 Nov '15

Hi, I've been experimenting with the new Connect engine and the ODBC table type. I've installed MariaDB 10.1.17 on a test machine. I have an ODBC diver connected to a C-ISAM database. I am able to use this ODBC to connect from a MS Access 2013 database and despite some restrictions related to the C-ISAM DB it works well I have also been able to connect successfully from MariaDB and create connect tables. The only issue I'm having with the ODBC table type is the lack of indexes. However, I have noticed that in the MariaDB documentation accessible from https://mariadb.com/kb/en/mariadb/connect-table-types-odbc-table-type-acces… there is a note :- "Version 1.04 (from MariaDB 10.1.6<https://mariadb.com/kb/en/mariadb-1016-release-notes/>) adds remote indexing facility to the ODBC table type." As I've now installed 10.1.17 on my test machine, would someone be able to provide more information on the status of remote indexing, how it works and on how I may be able to make use of this? I am using HeidiSQL (Vers. 9.1.0.4867) as a front end tool and when I try to create indexes for the connect tables I get a message "SQL Error (1105): Table type ODBC is not indexable". Kind Regards, Bruce Carlson
