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.
- a MooseFS storage mounted on every nebula host under the same folder (ex: /srv/vms);
Edit oned.conf accordingly:
IMAGE_REPOSITORY_PATH = /srv/vms/images
TM_MAD = [
name = "tm_moosefs",
executable = "one_tm",
arguments = "tm_moosefs/tm_moosefs.conf" ]
Configure nebula host to use the new transfer manager:
onehost create host01 im_kvm vmm_kvm tm_moosefs
If you move your
/var/lib/one inside moosefs (ex:
/srv/vms/one) and symlink it back, you can easily achieve database replication with sqlite for easy frontend migration.
