[Maria-discuss] Table encryption 10.1.4
by Rhys Campbell 16 Apr '15

16 Apr '15

Hi All, Been playing with encryption in 10.1.4 today and there's a few issues... Firstly the manual<https://mariadb.com/kb/en/mariadb/table-encryption/> gives the following example... "Example my.cnf to enable XtraDB encryption: [mysqld] file-key-management file-key-management-filename = /mount/usb1/keys.txt innodb-encrypt-tables innodb-encrypt-logs innodb-encryption-threads=4" But doesn't make mention of the fact you need to add.. plugin-load-add=file_key_management.so for this to work. Secondly... With this config.. "plugin-load-add=file_key_management.so file_key_management file_key_management_filename = /home/rcampbel/key.enc file_key_management_filekey = FILE:/home/rcampbel/keyfile.txt file_key_management_encryption_algorithm = AES_CBC innodb-encrypt-tables innodb-encrypt-logs innodb-encryption-threads = 4" I receive the following error... ERROR Innodb: Tablespace id 0 encrypted but encryption service not available. Can't continue opening tablespace." Then if I comment out inndob-encrypt-tables we get a step further but it complains.. "unknown option -innodb-encrypt-logs" <- documentation for 10.1.4 says different<https://mariadb.com/kb/en/mariadb/table-encryption/> If I change this to... innodb-encrypt-log The server then starts up successfully. Here's a snip of some relevant variables... [cid:image001.png@01D07869.79EBCC60] After this I do seem to be able to dynamically set innodb_encrypt_tables and create an encrypted table... [cid:image002.png@01D0786A.287E0B80] Side note file_key_management_plugin.so is missing from the 10.1.3 .tar.gz bundles Rhys Campbell Database Administrator TradingScreen, Inc. 23 York House, 5th Floor London WC2B 6UJ Email: rhys.campbell(a)tradingscreen.com<mailto:rhys.campbell@tradingscreen.com> Follow TradingScreen on Twitter<http://twitter.com/#!/TradingScreen> , Facebook<http://www.facebook.com/pages/TradingScreen/214046251945650> and our blog Trading Smarter<tradingsmarter.tradingscreen.com> This message is intended only for the recipient(s) named above and may contain confidential information.

[Maria-discuss] enforce_storage_engine
by Ian Gilfillan 16 Apr '15

16 Apr '15

Hi What is the reason for the the new enforce_storage_engine option being session only? Percona's implementation is global, and I realise there was a request to make it less strict, and be overridden by session for users with the super privilege, but surely it would make sense to allow a global default to be set, rather than just session only? The notes say that it was implemented based on default_storage_engine, but that variable is global and session, not just session. ian

[Maria-discuss] Does user have SUPER privilege?
by Rasmus Johansson 15 Apr '15

15 Apr '15

Hi, I was wondering if there is a straight forward way to check whether a user has SUPER privileges or not. I came up with doing the following: --check for user’s Super_Priv on the current host SELECT Super_Priv FROM mysql.user WHERE user = 'user1' AND host = 'host1'; --and then also check for user on whatever (%) host: SELECT Super_Priv FROM mysql.user WHERE user = 'user1' AND host = '%' But is there some more convenient way of doing it, maybe using SHOW GRANTS?

[Maria-discuss] MySQL for Database Administrators Ed 3.1
by Lukas Lehner 15 Apr '15

15 Apr '15

Hi I will attend "MySQL for Database Administrators Ed 3.1" from Oracle University. I will take 1Z0-883 "OCP MySQL 5.6 Database Administrator" exam. I choose Oracle University because of their high quality education (did quite a lot of courses at them). On my job I will work mainly with MariaDB and Galera Cluster. Is this exam and Oracle University course helpful for me? I have a background with classic Oracle RDBMs. cheers

[Maria-discuss] SHOW GRANTS change?
by Felipe Gasper 15 Apr '15

15 Apr '15

Hi all, I’ve noticed that MariaDB 10.0.14 shows an IDENTIFIED BY PASSWORD .. section in SHOW GRANTS, but 10.0.17 doesn’t show the password. I can’t find anything to this effect in the changelog; was this an intended change, or is it a bug? The MariaDB docs show SHOW GRANTS behaving without the password dump. Thank you! -FG

[Maria-discuss] New Question: Determining size of a row in bytes
by AskMonty KB 14 Apr '15

14 Apr '15

Hello, A new question has been asked in "MariaDB Community" by shortwave. Please answer it at http://mariadb.com/kb/en/determining-size-of-a-row-in-bytes/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have a small but essential requirement that is making me seriously consider a shift away from MySQL and I am wondering if MariaDB is a viable alternative. I need to measure the size of a row in bytes (easily). Specifically, a table consists of rows belonging to several users. I need to know how much disk space is consumed by each of those users. The only solution I can find in MySQL documentation/forums are inefficient and inaccurate approximations. Does MariaDB provide some way of doing this easily? I have to do it on multiple tables which will probably change, so I don't want to build maintenance overheads in. Also obviously I don't want too much of a performance hit. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/determining-size-of-a-row-in-bytes/

Please answer it at http://mariadb.com/kb/en/will-mariadb-101x-pick-up-mysql-577-system-variabl… as the person asking the question may not be subscribed to the mailing list. -------------------------------- Will MariaDB 10.1.X pick up MySQL 5.7.7 system variable changes for innodb? http://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb… • innodb_large_prefix is enabled by default in MySQL 5.7.7. This change coincides with the default value change for innodb_file_format, which is set to Barracuda by default in MySQL 5.7.7. Together, these default value changes allow larger column prefix indexes to be created when using ROW_FORMAT=DYNAMIC or ROW_FORMAT=COMPRESSED. If either option is set to a non-default value, column prefixes are silently truncated to 768 bytes. innodb_large_prefix is deprecated in MySQL 5.7.7, and will be removed in a future release. innodb_large_prefix was introduced in MySQL 5.5 to allow users to create tables compatible with the InnoDB Plugin in MySQL 5.1, which has reached the end of its product lifecycle. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/will-mariadb-101x-pick-up-mysql-577-system-variabl…

[Maria-discuss] Query exceeding 16384 bytes, skipping. Probably a bulk insert query.
by Umarzuki Mochlis 02 Apr '15

02 Apr '15

When I'm restoring dump of all database to one of my MariaDB 10.0 nodes (2 nodes galera cluster), I saw "Query exceeding 16384 bytes, skipping. Probably a bulk insert query.". So I ran again mysqldump for all database and diff with its original dump. There's a lot of differences. Where should I configure on my.cnf to allow each query from dump running successfully? Thanks.

[Maria-discuss] New Question: Strange issue with a complex stored procedure and Union Query

[Maria-discuss] New Question: Please list OS requirements.
by AskMonty KB 31 Mar '15

31 Mar '15

Hello, A new question has been asked in "Graphical Clients" by openiduser56. Please answer it at http://mariadb.com/kb/en/please-list-os-requirements/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- It' quite annoying to have to click around the destination website to try to work out what it takes to actually run the tool. I suspect most people looking for a GUI tool already have an operating system they want it to run on, and sometimes even restrictions on how much extra stuff they can install to get it working. So saying "runs on MacOS... you just need Parallels and a Windows licence" is unlikely to make sense. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/please-list-os-requirements/

Hi, It seems that source package of MariaDB 10.0.17 for Ubuntu Precise Pangolin (12.04 LTS) isn't provided. Binary packages for Precise Pangolin are provided. mariadb-10.0_10.0.17+maria-1~trusty.dsc (for Trusty Tahr) and mariadb-10.0_10.0.17+maria-1~utopic.dsc (for Utopic Unicorn) exist at: http://mirror.jmu.edu/pub/mariadb/repo/10.0/ubuntu/pool/main/m/mariadb-10.0/ But for Precise doesn't exist at there. Is Precise support finished? Could you confirm it? FYI: Source package of MariaDB 5.5.42 for Ubuntu Precise Pangolin (12.04 LTS) is provided. http://mirror.jmu.edu/pub/mariadb/repo/5.5/ubuntu/pool/main/m/mariadb-5.5/ Thanks, -- kou

[Maria-discuss] Reason for changing the thread_pool_size default value?
by Ian Gilfillan 19 Mar '15

19 Mar '15

Hi What was the reason for changing the default thread_pool_size from the number of CPU's to 8? If I look at the history of sql_vars.cc - https://github.com/MariaDB/server/commits/10.1/sql/sys_vars.cc?page=2 - the commit made on the 17th of November still has it as the number of CPU's, but the next commit on the 2nd of December has it at 8. This doesn't appear as a change in the summary. ian

[Maria-discuss] Error Message spelling mistake

I feel like a bit of a pedant reporting this... "Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'Error: connecting slave requested to start from GTID 1-1-7, which is not in the master's binlog. Since the master's binlog contains GTIDs with higher sequence numbers, it probably means that the slave has diverged due to executing extra errorneous transactions'" Errorneous should be erroneous Rhys Campbell Database Administrator TradingScreen, Inc. 23 York House, 5th Floor London WC2B 6UJ Email: rhys.james.campbell(a)googlemail.com<mailto:rhys.james.campbell@googlemail.com> Follow TradingScreen on Twitter<http://twitter.com/#!/TradingScreen> , Facebook<http://www.facebook.com/pages/TradingScreen/214046251945650> and our blog Trading Smarter<tradingsmarter.tradingscreen.com> This message is intended only for the recipient(s) named above and may contain confidential information.

[Maria-discuss] Enabling feedback pluging for MariaDB 10.1.4
by Michael Widenius 12 Mar '15

12 Mar '15

Hi! We had originally planned to enable the feedback plugin by default for the Alpha and Beta stages of MariaDB 10.1, but we forgot to do this for the alpha so I suggested Sergei today that we should enable it for the beta period of MariaDB 10.0 We agreed that before doing this we would have a discussion on the maria developer list to explain why we would like to do this. The reason we would like to enable it is to get information about which features people are testing and using in MariaDB 10.1, so that we can concentrate our testing and bug fixing during the beta phase for those areas that people are actually using. This would help our development work a lot and would also help us to plan for MariaDB 10.2 development. Anyone will be able to disable the feedback plugin by adding: --feedback=OFF to their my.cnf file. In MariaDB 10.1 gamma/release we would make it default OFF again. We will of course inform everyone about this change, including how to disable the feedback, in the MariaDB changelog and release notes. We do of course hope that as many as possible will have it on, even after gamma, to help us with our development work! Information about the MariaDB feedback plugin and the statistics it provides can be found at: http://mariadb.org/feedback_plugin https://mariadb.com/kb/feedback-plugin As most MariaDB users should know, the feedback is totally anonymous and no private or sensitive information is being sent. Any comments, suggestions or recommendations? Regards, Michael Widenius Creator of MySQL and MariaDB

[Maria-discuss] mariadb 10.0.17 keeps crashing
by Gabriel Sosa 04 Mar '15

04 Mar '15

Hello, I've been a proudly user of mariadb 5.5.x for a long time now but given the nice feature setI decided to give mariadb 10.x a try. I took one of our current slaves running mariadb 5.5.x (on centos 6.5) and followed the upgrade steps using yum and ran *mysql_upgrade*. The upgrade ran without any trouble...then I moved a huge table (about 1B records right now) from InnoDB to TokuDB. Now, every couple of hours I find that the replication is far behind the master and the reason is because this server keeps checking tables marked as crashed.... I can't seems to find any indicator of OOM killer in the system logs NOR anything related to that in the mysql log, the only clue I have is: --------------- *150303 10:08:57 mysqld_safe Number of processes running now: 0* *150303 10:08:57 mysqld_safe mysqld restarted* 150303 10:08:58 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release. 150303 10:08:59 [Warning] option 'innodb-status-file': boolean value 'ib_status' wasn't recognized.

[Maria-discuss] Questions on image data should be stored in database or not?
by Peter Boston 04 Mar '15

04 Mar '15

I don't know the following questions are valid here or not. I just hope I get some help from experienced experts here. I am planning to use MariaDB on 64bit Linux for a new medical application project. I have to store lots of images. The size of one image is about 263KB. There are about 50 images per patient. It's about 14MB. I have two options here for these image data: Option A: store them in file system and have their location linked in database table; Option B: store them in database in a separated table as BOLB with a unique id; I know there are lots of implementations go with Option A. My concern about Option A is the security and backup. I have to do them separately. Do you have any good idea how to do them? For Option B, I am worry about the size of that table and the database. I read somewhere saying the BOLB and TEXT columns in a table are not stored "inline" and will not be counted to the table size. Where I can find the detailed information about this? Oracle has a special way to handle this situation and is pushing save images into database. Is there a similar mechanism in MariaDB? How about compress a series of images for a patient in Option B? Is it worthy to scarify perform for gaining some spaces? Eventually the data size will be very big, what are the options for me to cleanup and archive old data, including the image data? Thanks, Peter

[Maria-discuss] stored programs
by Federico Razzoli 04 Mar '15

04 Mar '15

Reading 10.0.3 release notes: https://mariadb.com/kb/en/mariadb/mariadb-1013-release-notes/ I see that IF EXISTS, IF NOT EXISTS and OR REPLACE are now almost consistent. "Almost" means that... OR REPLACE still doesn't apply to stored procedures, functions, triggers, events. Recently, during a public session, a PostgreSQL user asked me if MariaDB supports stored procedures - in his opinion, MySQL doesn't, no matter what the manual says. Unfortunately my answer was that MariaDB support for stored procedure is the same as MySQL ("so the answer is no", he said). I feel that these features are generally ignored. I don't understand the reason. While they have many problems in MariaDB/MySQL, some people still tries to use them. Even more people would use them if some developement was made on them. They are also used by important projects like Common Schema and Flexviews, but I'm sure that the authors have to struggle against limitations every time they change a line of code. I struggled hards for a much easier project - an SQL unit test tool. I have several problems in mind: performance, lack of variable number of arguments, cannot prepare a statement from a local variable, no debugger, no way to see the call stack... I'm writing this because I love MariaDB. This is not a hateful criticism: this is a request for something I waited for many years. I hope that you will keep procedures in mind, while planning the next major release. Regards Federico

[Maria-discuss] MaxScale Multiple Masters
by Riz Plate 03 Mar '15

03 Mar '15

Hi I have a very basic scenario, we have one database which is running out of space. database have some tables with incremental primary key ids. 1- for new ids , we want to send read/write to new server and preferably , do id based statement routing i.e. if id%2=0 push to new-server1 , else read/write to new-server2. 2- some tables are created dynamically i.e. dynamic_table_123. we want to send 123%2=0 to new-server1 else read/write to new-server2. 3- all statements in above #1, #2 should go to same MaxScale abstraction i.e. application should not have logic for routing. Can we do this with MaxsScale? what are the configuraion readwriterouter or the cluster? Thanks for your insight and recommendations. Thanks

[Maria-discuss] Serious problem with latest (10.0.16) Windows installer - destroys services.
by Peter Laursen 02 Mar '15

02 Mar '15

I have MariaDB 5.5, 10.0 and 10.1 installed (as Windows services named 'maria55'. 'maria10' and 'maria10_1' ) and always update them to latest soon after an update is available. Yesterday morning I installed 10.0.16 on top of 10.0.15 using the .msi installer. When I tried to connect to it a few hours later it was not possible. I thought the service might not be running. It wasn't. Actually it did not exist anymore at all! "net start maria10" returned "service does not exist" (and indeed it did not appear in Windows "services management" interface). I copied the /datadir, uninstalle , did a fresh install of 10.0.16d (choosing the option not to upgrade any existing server) and copied the old /datadir back. Now Maria 10.0(.16) works again. But now I see that the 'maria55' service is also gone from the system. Files are intact. I can repeat the exercise I did with 10.0 of course or install service again from commandline. Not a big problem, but very annoying and waste of time. MariaDB 10.1 installaton is not affected. 5 diiferent Oracle/MySQL servers (from 5.0 to 5.7) also are not. I need all those instances for application testing. Questions: * Has somebody else experienced this? * Has somebody replaced @wlad as maintainer of Windows installers? @wlad was the only person who ever was able to write reasonable MySQL/MariaDB installers. So I would regret that. It is perfectly legal on Windows to have multiple MariaDB servers simultaneously running as Windows services. They won't conflict as long as service name, port, basedir and datadir are all different. What happens with one should not affect another. I the installer does not respect this, it is a bug. -- Peter -- Webyog

[Maria-discuss] Giving up on dynamic columns
by Tom Worster 02 Mar '15

02 Mar '15

I discovered this showstopper on Friday while working with real data in development of a new app. I managed to narrow it down today and filed the bug report. https://mariadb.atlassian.net/browse/MDEV-7650 Looks like Maria saves an illegally formatted dyncol string if a dynamic column is longer than 64kB and is not alphabetically last by name among the dynamic column in the blob. Tbh, even is this were fixed tomorrow so I could proceed with my work, I'm not sure I would use dyncols. My confidence in the feature has been shaken. It's a pity because the Active Record ORM extension I wrote was working. Tom

[Maria-discuss] myisam_use_mmap unstable in MariaDB 10.0.x
by Reindl Harald 01 Mar '15

01 Mar '15

historical: http://lists.mysql.com/mysql/226361 after it turned out to be stable in 2013/2014 upgrade to MariaDB 10.0.17 yesterday and the logs started with "table corrupt", "table not closed properly" and so on for tables which where not only read this time not with 'mysqld got signal 11' but "only" corrupted MyISAM files and after disable 'myisam_use_mmap' all is clean and stable over hours BTW a 'repair table' don't delete the TMM file leading in a 'optimize table' later failing until you delete the file manually from disk __________________________________________________________________ this configuration is unchanged for years and so my only conclusion is that Oracle managed to kill the feature again, this is also confirmed for Percona Server 5.6 where even queries fail confirmed from another sysadmin which found out that playing with my settings leaded to problems while here MariaDB 5.5.x was in use and hence no troubles - given that 'myisam_use_mmap' is borked at MariaDB 10.x and Percona 5.6 it's likely a backport from MySQL 5.6 delay-key-write = ALL concurrent_insert = 2 open-files-limit = 750000 myisam-recover-options = "FORCE" myisam_use_mmap = 0 wait_timeout = 300 interactive_timeout = 300 max_allowed_packet = 200M max_connections = 500 max_tmp_tables = 150 max_connect_errors = 250 max_delayed_threads = 32 flush_time = 0 query_cache_limit = 256K query_cache_min_res_unit = 1K query_cache_size = 1280M query_cache_type = 1 table_cache = 10000 table_definition_cache = 10000 thread_cache_size = 400 tmp_table_size = 256M max_heap_table_size = 256M key_buffer_size = 256M sort_buffer_size = 256K myisam_sort_buffer_size = 15M join_buffer_size = 1M preload_buffer_size = 128K read_buffer_size = 128K read_rnd_buffer_size = 128K

[Maria-discuss] warning from binary tarball file installation.

I am installing mariadb-10.0.15 on Fedora 20 from a binary tarball file. After several changes on .my.cnf file, I minimized the installation warning to three. I am using the default my-large.cnf file from the release.

[Maria-discuss] Default privileges for anon. user.

Hi!

[Maria-discuss] questions from a new user
by Peter Boston 25 Feb '15

25 Feb '15

I am new to use mariadb on linux machine. I am using Fedora 20 and I have downloaded the mariadb 10.0.15 tar.gz file and its instruction. I removed the existing mariadb from my Fedora 20. I have installed the mariadb on my machine by following the official instruction. It seems successful (without error) but I cannot start it as expected. I also have few other basic questions. Some background information here: this database will be accessed by a local application. This local application may be running under a general user account, user1. I installed it in /var/local as a root user. Questions: 1. How to uninstall it completely? I want to try again to see if I did anything wrong before. 2. Because it will be accessed by a local application and the local application will be running by a general user, user1, should I install it with user1? 3. Basically I am confused with these three users: user1, mysql and root. "user1" will be used to run the application and login the machine. "mysql" will be used to connect the mariadb. "root" will be used to install mariadb into /usr/local. Who will start the mariadb? It will be "root", I guess. But if "root" starts the service, "user1" and "mysql" don't have problem to access its resources? 4. If I don't want to install it as root, can I still install it under the /usr/local directory? 5. I renamed the my-large.cnf to .my.cnf and uncomment the InnoDB table section. Is this only change I need to make if I want to use InnoDB? should I disable the myisam? how? 6. where should I put the .my.cnf file? put into the home directory of the user who starts the mariadb or the user who logon the system if they are different? 7. there is a my.cnf file from the Fedora 20 installation, when I start mariadb without the "--defaults-file=~/.my.cnf" option, I will get the following error from the log: [ERROR] mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 "No such file or directory") I have to manually create the mysqld folder inside the /var/run folder each time after reboot. how to avoid this? 8. After started with that "old" my.cnf, I try to stop the mariadb but cannot because I cannot find its service name: [user1@dev2 mysql]$ ./bin/mysqladmin -u root -p status Enter password: Uptime: 685 Threads: 1 Questions: 3 Slow queries: 0 Opens: 0 Flush tables: 1 Open tables: 62 Queries per second avg: 0.004 [user1@dev2 mysql]$ sudo systemctl status mariadb.service mariadb.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) [user1@dev2 mysql]$ sudo systemctl status mysql.service mysql.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) [user1@dev2 mysql]$ sudo systemctl status mysqld.service mysqld.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) how stop it? 9. if I start mariadb with the renamed my-large.cnf ([root@dev2 mysql]# ./bin/mysqld_safe --defaults-file=~/.my.cnf --user=mysql), I got the following error: 150225 0:09:28 [ERROR] Can't open the mysql.plugin table.

[Maria-discuss] SHOW GRANTS: MySQL vs. MariaDB
by Felipe Gasper 24 Feb '15

24 Feb '15

Hi all, We have custom logic in place that “suspends” a MySQL user by: - reversing the password hash - replacing the leading “*” with “-” In other words (pseudo-code): my $hash = SELECT password FROM mysql.user WHERE user = 'theuser'; $hash = $hash.replace(/^\*/,"").reverse(); UPDATE mysql.user SET password = "-$hash" WHERE user = 'theuser'; I have noticed that MySQL’s SHOW GRANTS reports these “suspended” password hashes with the leading dash “fixed” to a leading asterisk. MariaDB 10, though, has SHOW GRANTS report the literal contents of mysql.user. Is this behavior by design in MariaDB 10? Is it behavior that we can depend on moving forward? -FG

[Maria-discuss] Mariadb galera tolerance to network and io latency
by Lyle Franklin 21 Feb '15

21 Feb '15

Recently we observed that when network and IO latency increased significantly (and correspondingly, that bandwidth reduced significantly) all nodes in a 3-node mariadb galera cluster reported the other nodes as partitioned. We understand that by default galera is configured to wait 6 seconds before declaring other nodes partitioned. Is there any additional documentation on the performance on mariadb/galera with respect to network/IO latency and bandwidth? Are there hard limits beyond which a cluster is known to fail, and soft limits which are known to degrade performance? Thanks, Rob and Lyle Cloud Foundry Core Services

Hi Nirbhay, thank you very much for your answer. This cluster is already in production, with few databases (for mail user authentication, radius authentication, and so on). My question is: what would will happen if I change wsrep_sst_method on one node? How the other node can be "synced" if wsrep_sst_method is different (even for a few seconds)? Thank you, regards

For example: 1) shutdown node 1 2) change config to xtrabackup-v2 on node 1 3) restart node 1? 4) shutdown node 2 5) change config to xtrabackup-v2 on node 2 6) restart node 2 ..and what about garbd on the third node? :) Thank you very much ----Messaggio originale---- Da: nirbhay(a)mariadb.com Data: 17/02/2015 14.22 A: "absolutely_free(a)libero.it"<absolutely_free(a)libero.it> Cc: "MariaDB discuss"<maria-discuss(a)lists.launchpad.net> Ogg: Re: [Maria-discuss] Switch from rsync to xtrabackup Hi!

Should I simply install percona package and change this configuration? Right, the package name is "percona-xtrabackup". wsrep_sst_method=rsync to wsrep_sst_method=xtrabackup ? Or rather go for "xtrabackup-v2".https://mariadb.com/kb/en/mariadb/galera-cluster-system-variables/#wsrep_sst_method SST methods other than "rsync" also require "wsrep_sst_auth" variables to be set.https://mariadb.com/kb/en/mariadb/galera-cluster-system-variables/#wsre… Best,Nirbhay Thank you very much _______________________________________________ Mailing list: https://launchpad.net/~maria-discuss Post to : maria-discuss(a)lists.launchpad.net Unsubscribe : https://launchpad.net/~maria-discuss More help : https://help.launchpad.net/ListHelp

Hi all, according to this URL: http://www.fromdual.com/huge-amount-of-time-wait-connections is it recommended to change default behavior of tcp_tw_reuse and tcp_tw_recycle? I am using two MariaDB nodes with haproxy, keepalived and garbd on third node. Thank you very much
