Re: [Maria-discuss] .ibd files remaining after DROP TABLE
by Andrew Braithwaite 17 Oct '14

Hi, It only seems to happen when replicating DROP TABLE IF NOT EXISTS from a master, not when running it directly on that server. I can replicate this problem every time.

[Maria-discuss] Aborted connection (Unknown error)
by Florent Bautista 15 Oct '14

15 Oct '14

Hi all, I'm getting annoying errors when I want to switch clients from MySQL to MariaDB. I use Debian Wheezy, and MariaDB 10.0 repositories, then I install mariadb-common & libmariadbclient. Then I restart services using MySQL Client Library and I have a lot of warnings like these on my MariaDB Server (with Galera or not) : [Warning] Aborted connection 136305 to db: 'db' user: 'user' host: 'xx.xx.xx.xx' (Unknown error) I do not have more information in logs. This is not a network problem, because it occurs with 127.0.0.1 too. What do I miss ? Thank you a lot. Florent

Compression is done by CPU in the MariaDB server (InnoDB/XtraDB storage engine). About Atomic Write, I understand there is missing code to have this feature to the TokuDB engine. Should I ask to the Mariadb dev team or the Tokutek dev team (or SanDisk/FusionIO dev team ?) to add it (maybe it’s technically no doable ?)? I would start from Tokutek dev team, I do not know fully how database tables are stored on Tokutek, but I do not see immediately a reason why atomic writes would not be possible. Do you think this can boost performances for huge TokuDB tables ? Atomic will boost performance but only if database is stored on device that supports atomic writes. R: Jan

[Maria-discuss] Possible? upgrading gallera cluster without service interruption
by Benoit Panizzon 30 Sep '14

30 Sep '14

Hello We would like to upgrade from 5.5.33a+maria-1~saucy to 5.5.39+maria-1~saucy on a running cluster without service interruption. So we took down one node, upgraded and restarted that instance... It fails to connect to the next gcomm server. MariaDB fails to start. We tested network connectivity, there is no issue we could detect. We downgraded back to 5.5.33a+maria-1~saucy and the connectivity issue disappeared. So my question here is: Is it possible to upgrade the cluster without interruption, or do we have to shut the whole cluster down, upgrade every node and then restart everything? Kind regards Benoit Panizzon -- I m p r o W a r e A G - ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 07 CH-4133 Pratteln Fax +41 61 826 93 02 Schweiz Web http://www.imp.ch ______________________________________________________

Hi Christophe, This is Dhananjoy Das (Joy) from SanDisk (formally Fusion-io inc.,) contributor to the NVM Compression. In regards to your query on access to NVMFS, yes currently its supported on Atomics Series of ioMemory cards(PX/SX), I would suggest its best to get in touch with the SanDisk Sales team (formally Fusion-io inc.,) and request for the LA NVMFS 1.0 (Limited Edition). Additionally, NVM Compression (changes are part of InnoDB/XtraDB) is independent of the TokuDB DB-engine. Hope that help, feel free to reach out. Thanks, Dhananjoy Das (Joy) mailto:Dhananjoy.Das@SanDisk.com Sr. Architect, SanDisk Corporation From: Christophe Le Roux <christophe.le.roux(a)fr.clara.net<mailto:christophe.le.roux@fr.clara.net>> Subject: [Maria-discuss] MariaDB,TokuDB and FusionIO Date: 26 September 2014 19:05:49 GMT+8 To: "maria-discuss(a)lists.launchpad.net<mailto:maria-discuss@lists.launchpad.net>" <maria-discuss(a)lists.launchpad.net<mailto:maria-discuss@lists.launchpad.net>> Hello, After reading the previous discussion about Fusion IO with Torben Mathiasen contribution, I have some questions. I understand that the nvmfs is developed by FusionIO and is closed source. Can we have this module (I think it's a kernel module , right ?) if we buy a new FusionIO card (Only with Atomic Series?)? Is this module ok with "old" FusionIO card (iodrive2) ? About AtomicWrites and the NVM compression, can these features be added to the TukuDB engine ? Can the TokuDB compression and the NVM compression be working together or if we enable one, we need to disable the other ?
