Aug 6 12:24:24 testserver mysqld: 150806 12:24:24 [Note] /usr/libexec/mysqld (mysqld 10.0.20-MariaDB) starting as process 115096 ... why is this now stdout instead mysql logs? on systemd based distributions that spits now to the global syslog and finally on machines restarting 2 instances every hour for backup reasons it annoys until 10.0.19 or 10.0.20 that was not this way

[Maria-discuss] Virtual CHECK constraint using Virtual columns
by Peter Laursen 16 Oct '16

16 Oct '16

As described in this Blog http://mablomy.blogspot.dk/2016/04/check-constraint-for-mysql-not-null-on.h…. A very nice hack/trick IMO. However it is not working with MariaDB as VC's cannot be declared NOT NULL. What prevents that? -- Peter -- Webyog

[Maria-discuss] New Question: Swap usage won't decrease
by AskMonty KB 28 Jun '16

Hello, A new question has been asked in "MariaDB FAQ" by alexandraarreaza. Please answer it at http://mariadb.com/kb/en/swap-usage-wont-decrease/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- We have a 5 DB nodes Galera Cluster in Production (MariaDB 10.0). About a week ago a DB import was performed over an existing DB (Its size ~30G) and during this process, all DB nodes started complaining about swap usage and haven't stopped complaining since then (e.g: One of them would be using 814 MB out of 4095 MB). I have read a good few articles about MySQL and swapping issues (this is a good one: https://blog.jcole.us/2010/09/28/mysql-swap-insanity-and-the-numa-architect…) and also about swapping in MariaDB (https://mariadb.com/kb/en/mariadb/configuring-swappiness/) but still can't find out a way of solving this problem without restarting MySQL. We have NUMA architecture with 2 nodes and 96G of RAM. Our buffer pool size is 70G and it is set to use 12 innodb_buffer_pool_instances. 1) Is there any fix to this situation besides restarting MySQL? 2) Is there a way of tuning our cluster to avoid swapping in the future? Thanks. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/swap-usage-wont-decrease/

by AskMonty KB 27 Jun '16

Hello, A new question has been asked in "MariaDB FAQ" by palash.harchandani93_43595. Please answer it at http://mariadb.com/kb/en/snchronizing-monyog-on-two-servers/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Is it possible to monitor MariaDB database from two servers where MONyog is installed and keep them synchronized. By Synchronization i mean if i add a new monitor on one server then that monitor should automatically be added on the second server?? This is important as if one server where monitoring is done goes down MONyog wil stop monitoring the database. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/snchronizing-monyog-on-two-servers/
