Open@BNCF - LinuxDay 2011 a Pisa

Submitted by gionn on 22/10/2011 19:21

This year I've joined the LinuxDay of Pisa with a talk about my recent works in LiberSoft to the BNCF.

These includes:
* Desktop migration to Ubuntu Linux (10.04 LTS) with centralized login management (OpenLDAP) and shared /home with MooseFS;
* OpenNebula KVM-based Cloud with MooseFS as backend storage (and publishing of the relative transfer manager: https://github.com/libersoft/opennebula-tm-moosefs);
* GlusterFS-based infrastructure for the national italian legal deposit of books (italian article: http://www.bncf.firenze.sbn.it/pagina.php?id=212&rigamenu=Magazzini%20Di...)

ZFS + GlusterFS on Linux

Submitted by gionn on 27/08/2011 11:44

Time is almost ripe for start using the native ZFS port on Linux (http://zfsonlinux.org/), and to increase the performances, reliability and space usage of our affordable distributed opensource storage solution.

Installing ZFS on Debian/Ubuntu is straightforward: you need first to build the SPL (Solaris Porting Layer) and after ZFS itself.

Download the latest SPL package, unpack it and build:

  1. sudo apt-get install build-essential gawk alien fakeroot linux-headers-$(uname -r)
  2. ./configure
  3. make deb
  4. dpkg -i *.deb

I've written a post for the OpenNebula official blog about the usage of MooseFS as shared storage:
