Hi all,

First at all I'm glad to write to the list :D thanks for reading!

I'm currently experimenting with lot of ideas to store the
instances(/var/lib/nova/instances) and do a live migration with them, well
here it's a tiny resume:

DRBD + OCFS2: Works pretty well but as it depends on DRBD which it's a raid
1 system it can't grow any further than the initial size... bad idea if you
want some scalability

GlusterFS: A bit slow, it can take some minutes to replicate but works, the
only problem that it has it's that you can't perform a live migration, the
reason, cache != none or that's what the logs says

Ceph: It runs pretty good tests, but it's slow with the machines in my lab,
and throw some errors about being too slow. Anyway, I tried the live
migration and it didn't work either.

Now I'm currently starting my test with MooseFS but don't know yet if it
will work, according to the openstack manual it's a good idea, but I will
like to have the experience of the list on this matter, does anyone try any
of this options or another successfully? or have other options that I
haven't found yet?

Thanks in advance for all you answer!
