MooseFS optimized version of the tm_shared driver for OpenNebula (up to 3.2): speed improvements on cloning using mfsmakesnapshot utility instead of cp -R)

opennebula-tm-moosefs

OpenNebula is a fully open-source toolkit to build IaaS Private, Public and Hybrid Clouds.

MooseFS is a fault tolerant, network distributed file system. It spreads data over several physical servers which are visible to the user as one resource.

By combining these two components you can build an effective cloud with commodity hardware and cheap storage, ensuring high availability, replication and scalability.

Installation

Requires a MooseFS filesystem mounted on every OpenNebula host under the same folder (e.g.: /srv/vms);

Configure your oned.conf accordingly:

VM_DIR=/srv/vms/deploy
IMAGE_REPOSITORY_PATH = /srv/vms/images
TM_MAD = [
    name       = "tm_moosefs",
    executable = "one_tm",
    arguments  = "tm_moosefs/tm_moosefs.conf" ]

Copy the tm_moosefs folder into /etc/one or $ONE-LOCATION/etc

Copy the tm_commands/moosefs into /usr/lib/one/tm_commands

Configure OpenNebula hosts to use the new transfer manager with:

$ onehost create host01 im_kvm vmm_kvm tm_moosefs dummy

Goodies

When using SQLite database, if you move your /var/lib/one (and symlink it back) or you do a self-contained installation into the MooseFS volume (e.g.: /srv/vms/one), you can easily achieve database replication and a simple fail-over of the frontend on another machine.
