Dear list, this is my 1st time testing Galera Cluster with MariaDB 10.1. With version 10.1.9 I get the following error using xtrabackup-v2 for SST: Dec 7 18:32:21 wsc-db01a-test mysqld: 2015-12-07 18:32:21 140026872588032 [Note] WSREP: Member 1.0 () requested state transfer from '*any*'.

[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 ?

Hi all, It turns out that what is considered to be the largest conference for those interested in the MySQL world, nowadays called the Percona Live Data Performance Conference, is requiring the community to vote on submissions that they would like to hear. Only after voting, will those with a certain threshold (not published) be sent to the next level for the program committee to vote on. Its clear that you *do not* have to be attending the event, but you do need to register to vote. I’m sure all of us would appreciate your votes. The people below offering talks are Sergei Golubchik, Sergei Petrunia, Michael “Monty” Widenius, Gerry Narvaja, Serge Frezefond, Anders Karlsson, and me, Colin Charles.

[Maria-discuss] New Question: Stored Procedures & Functions on nodes in a Galera Cluster
by AskMonty KB 03 Dec '15

03 Dec '15

Hello, A new question has been asked in "MariaDB Galera Cluster" by tim_peart_g. Please answer it at http://mariadb.com/kb/en/stored-procedures-functions-on-nodes-in-a-galera-c… as the person asking the question may not be subscribed to the mailing list. -------------------------------- I am at the planning stage of a new Galera/MariaDB cluster. I can find very little info on how Stored Procedures and Functions are handled across the cluster. Am I safe to assume that a Stored Procedure or Function which is defined on one cluster node is not automatically propagated to any of the other nodes in the cluster? If so, then what are the Best Practices regarding update of Stored Procedures and Functions across the Cluster? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/stored-procedures-functions-on-nodes-in-a-galera-c…
