[Maria-discuss] MariaDB 10.1.14 failure to initiate SST after RSU schema upgrade
by Mark Wadham 21 Jul '16

21 Jul '16

Hi, We have a repeatable failure to initiate IST with MariaDB 10.1.14 after performing a schema upgrade on a single node in RSU mode. The error condition is when there is a delete query in the format: delete from <table> where id >= <n> on the non-RSU cluster nodes while the node is disconnected from the cluster. On rejoining the node determines that it is in sync with the other cluster nodes and no IST is performed, despite the rows that were deleted in the cluster. If we then delete the rows manually from the joining node, mysqld immediately crashes on the other nodes because they can't execute the new write transaction. The process we followed is: 1. Set up a 3-node cluster, nodes 0,1,2 2. Enable RSU on node 0: SET GLOBAL wsrep_OSU_method='RSU'; 3. Isolate node 0 from the cluster: SET GLOBAL wsrep_cluster_address="gcomm://"; 4. Perform a backward-compatible schema change, since this is the point of this process. In our test we added a single column to a table with a default value of null. Additionally we deleted some rows from a table on nodes 1 and 2, with: delete from <table> where id >= 100; which affected around 20 rows. 5. Rejoin the node to the cluster: SET GLOBAL wsrep_cluster_address="<gcomm string from config file>"; At this point the node immediately rejoins without doing IST and believes it is in sync, yet the rows are deleted on nodes 1 and 2 but not node 0. Interestingly if the delete query is: delete from <table> where id = <n>; there is no problem. Also we have not had any issue with syncing INSERT and UPDATE statements. A combination of INSERT, UPDATE and DELETE where id >= resulted in the insert/update statements being synced but the deletes not synced. It is as if the quorum somehow doesn't recognise delete where id >= as an event. Our next test cases are: 1. Switching node 0 back to TOI mode before rejoining the cluster, although I can't really see how this would make a difference. 2. Upgrading to MariaDB 10.1.16 which was released a couple of days ago. 3. Testing whether regular IST is affected, ie IST that should occur normally without switching to RSU mode or dropping a node out of the cluster. This seems like a pretty basic failure and I'm concerned that it may also affect regular IST, i.e. a node falling behind the cluster for normal reasons without any involvement of RSU mode, which would effectively make the whole system useless if it could randomly drop delete statements. If anyone can shed any light on why this may be happening we would be very grateful! Thanks, Mark

[Maria-discuss] New Question: MariaDB Installation error
by AskMonty KB 20 Jul '16

20 Jul '16

Hello, A new question has been asked in "MariaDB FAQ" by palash.harchandani93_43595. Please answer it at http://mariadb.com/kb/en/mariadb-installation-error/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I am getting error with ibdata1 auto extending of the files when running mysql_install_db and it fills the file with zeroes. But when i delete the ibdata and run the mysql_install_db again everything goes fine. Also the size in my.cnf file is innodb_data_file_path = ibdata1:100M:autoextend InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data! How exactly to resolve the error? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-installation-error/

[Maria-discuss] Key lengths for file_key_management plugin

19 Jul '16

I've asked directly in the documentation page, but maybe someone will know answer here: https://mariadb.com/kb/en/mariadb/data-at-rest-encryption/#comment_2346 In that article it is said that 128, 192 or 256-bit keys are supported, but later AES_CTR and AES_CBC modes talk only about 128bit keys. What piece of information am I missing? Honza
