[one-users] experiences with distributed FS?

[Maxim Mikheev]

Hi Joao.
I made a similar search recently. Here is my results:
Lustre - does not have redundancy, If you will use file striping between 
nodes and one nodes go offline all data are not available.
Gluster - does not support KVM virtualization. Software developer lead 
mentioned that it will be fixed in next release (April).
Shipping Dog - Working only with images does not allow to store plain 
files on it. one image can be connected to only one VM per a time.
eXtremFS - does not have support. If something not working it is your 
problem even you ready to pay for fixing.

And my choice: MooseFS - redundant any node can go offline and data will 
be available, scalable, with striping, with CoW, Create copy of huge 
images in a second, has internal checksum correction, has commercial 
support, data deduplication (commercial version only) and many other 
features.

there are plugging for OpenNebula. It has some bugs but you can start 
from this point.

Regards,
     Max
