[Maria-discuss] Minor version upgrades across a cluster
by Craig Bailey 27 Oct '16

27 Oct '16

Hi, We have a three node MariaDB Galera cluster on version 10.1.14 an we would like to upgrade to 10.1.18. Our approach to this was to offline a node upgrade it and then add it back to the cluster and allow it to do an IST to catch up (rinse and repeat for other two nodes). However this would mean that we will have a period of time where nodes in the cluster will be on different minor versions, is this safe, or will it possibly cause some kind of data corruption or crash?

[Maria-discuss] wsrep-node-name vs. wsrep-node-address?
by l vic 25 Oct '16

25 Oct '16

Do I need to use "--wsrep-node-name" option with dns names to identify the node in Galera cluster instead of "wsrep-node-address", or is the "--wsrep-node-address=<dns-name>" supposed to work? Thanks,

[Maria-discuss] MariaDB and TLB misses / Large Pages
by J. Cassidy 21 Oct '16

21 Oct '16

Hello all, is there a reliable cookbook / checklist to implement Large Tables on a SuSE SLES 12 SP1 Linux distribution? I find there there is a lot of old/inaccurate/dodgy information on my search machine travels. The test setup is as follows- Everything enabled for Large Pages as per various online Fora. 128GB RAM 72GB InnoDB buffer size, eight instances. MariaDB is DB is defined in a 52GB RAM disk. (This is a test to tie down TLB and Lx cache misses and high CPU next activity) Any pointers/hints most welcome.

You made a question and also provided the answer. If you really need to run a storage engine optimized for a specific use case on an operating system that is not good for MySQL, use Docker :) Federico -------------------------------------------- Lun 17/10/16, Richard Bensley <richardbensley(a)gmail.com> ha scritto: Oggetto: Re: [Maria-discuss] MariaDB Server 10.3 notes A: "Rich Prohaska" <prohaska7(a)gmail.com> Cc: "Maria Discuss" <maria-discuss(a)lists.launchpad.net> Data: Lunedì 17 ottobre 2016, 17:10 With hyper-v becoming free, the arrival of the Linux subsystem, and docker for windows 10; there isn't much of an excuse to proclaim you are unable to use the Linux binaries.
