Re: configuration question

Hi Daniel,

Thanks for the answer!

I would like to setup my storage cluster with actual partition (2TB) and after setup the same boxes with one big 10TB partition on each box. My goal is to compare the two solutions in terms of performance.

I have a supplementary question: Is it possible to configure glusterfs with more than one partition in a brick? If yes, what's the syntax to use?

Thanks,

Fabrice

    Hi all,

    I need some advices for configuration of our brand new storage boxes
    with glusterfs.
    We have 2 boxes with each 10TB of disk space. This disk space is
    separated in 2TB partitions by autocarving on
    hardware controller. I want to aggregate all that disk space with
    glusterfs. I don't want to have HA.
    I know that it's possible.  But I would like to know what's the "good
    practice" to implement this configuration.

    Thanks in advance,

    Fabrice



Fabrice,

I installed a small cluster last week and I also had problems creating partitions with disks bigger than 2TB. This howto helped-me a lot: http://www.unixgods.org/~tilo/larger_2TB.html <http://www.unixgods.org/%7Etilo/larger_2TB.html>. In a few words, use parted to make the partitions and a different partition label called gpt. Maybe you will need to recompile your kernel.

If you only want to aggregate the space together and have a 20TB "disk" for you clients, them try reading http://www.gluster.org/docs/index.php/GlusterFS_Multi-server_Config_Example.

If you also want to do HA, having a copy of every file on both servers, then you will need AFR, read http://www.gluster.org/docs/index.php/GlusterFS_Translators#AFR_Example_in_Clustered_Mode.

If you are just starting with GlusterFS, I think you should also read http://www.gluster.org/docs/index.php/Getting_Started_with_GlusterFS.

Best regards,
Daniel Colchete
