[one-users] experiences with distributed FS?

[João Pagaime]

Hello all,

We're looking into the possibility of using a distributed FS, like 
glusterfs or similar solution for the image repository

Can anyone share his experiences on this topic?  any hints would be 
nice... Existing specific documentation? REcommendend configurations? 
Tested configurations? Things to watch out for? Things particular to 
open-nebula? Problems? Stability (is it maintainable without a general 
shutdown)?  Effort/learning curve ("large", "small", hours, days, 
weeks)? Any other information?

Thanks any way, best regards,
João
