How well did it work for you? I know GlusterFS does not care for data 
integrity and I'm concerned about potential inconsistencies due to lack of 
metadata server...

No no no. I strognly advise against Ceph. It is very sophisticated and 
fragile with huge and messy code base... Ceph is very unreliable, very slow 
and difficult to set up. Ceph couldn't care less for data integrity and in 
loing term data corruption is inevitable. I'm talking from experience. Please 
stay away from Ceph, it does not worth the effort.
