Which repository are you talking about? Is it yum.mariadb.org? If so there might be something you can do. The yum repositories on yum.mariadb.org are replicated on our mirror network. So, for example, you could change your mariadb.repo files to something similar to the following to use the osuosl mirror instead of yum.mariadb.org (I'm using rhel7-amd64 and MariaDB 10.0 in the example, change to whatever yum-based distro and MariaDB version you are using) :

[mariadb]

name = MariaDB

baseurl = http://ftp.osuosl.org/pub/mariadb/yum/10.0/rhel7-amd64

gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB

gpgcheck=1

It was about repo for Debian. (I saw it).

Was speaking with friend he updated to MariaDB 10.0.22 to test ClusterControl with and first and second : OK. Last one error 404.

Do you know which MariaDB mirror you are using for your Debian repository? If you go to the Repository Configuration Tool https://downloads.mariadb.org/mariadb/repositories/ and configure an example Debian repo, you can switch the mirror chosen for you to a different one.

We don't have a way to increase the bandwidth of a given mirror, but we have quite a few of them spread around the world, so you should be able to find one that works better than the one you are currently using. When configuring an example repository for Debian the repository configuration tool will only give you a choice of five or so nearby mirrors (based on geo-location) but there is a "Show all Mirrors" button that will give you the full list.

i tried any different and same problem (no example now), try to DL : http://archive.mariadb.org/mariadb-10.0.21/bintar-linux-x86_64/mariadb-10.0.21-linux-x86_64.tar.gz

Ok, so you're not using a repository, you're downloading a bintar.

You really do not want to use the archive.mariadb.org mirror. It is a historical archive of all MariaDB releases and is bandwidth-limited. A standard mirror will serve you much better. For example, the MariaDB 10.0.21 Linux x86_64 bintar from the OSUOSL mirror:

http://ftp.osuosl.org/pub/mariadb/mariadb-10.0.21/bintar-linux-x86_64/mariadb-10.0.21-linux-x86_64.tar.gz

...or the recently released 10.0.22:

http://ftp.osuosl.org/pub/mariadb/mariadb-10.0.22/bintar-linux-x86_64/mariadb-10.0.22-linux-x86_64.tar.gz

When you're on downloads.mariadb.org looking at a release you can change the mirror by scrolling down to the "Mirror" section in the right-side column, clicking on a different mirror, and waiting for the page to refresh.

I updated some servers 5~10 then :

yum install MariaDB-server MariaDB-client
Modules complémentaires chargés : fastestmirror, refresh-packagekit

http://yum.mariadb.org/10.0/centos6-amd64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 6 - "Couldn't resolve host 'yum.mariadb.org'"
Essai d'un autre miroir.
Erreur : Cannot retrieve repository metadata (repomd.xml) for repository: mariadb. Please verify its path and try again

got same problem with apt

Aurelien_LEQUOY: I'm able to successfully load http://yum.mariadb.org/10.0/centos6-amd64/repodata/repomd.xml (I tried just now) so I don't know why you're seeing the "Couldn't resolve..." error. You could try using the alternative mariadb.repo file I pasted above comment-77458, modified for rhel6-amd64.

For APT, it's impossible you're seeing the same error as there are no APT repositories on yum.mariadb.org. What is your actual error with APT?

Thanks.

no i got 404 for APT

But to what repository? It's definitely not the yum.mariadb.org repository.

yum.mariadb.org is now load-balanced across 4 different hosts, so it should be much faster

Unable to fix the APT 404 issue as I don't know which mirror was configured, so closing.
