Hi !

I have failover clusters (IMAP service) with 2 members configured with Ubuntu + Drbd + Ext4. My IMAP clusters works fine with ~ 50k email accounts.
See design here: http://adminlinux.com.br/my_imap_cluster_design.txt

I would like to use a distributed architecture of the filesystem to provide more processing power and availability to my clusters. As we know, Ext4 is a good filesystem but it isn't a distributed filesystem. So I would like to use Ceph in my clusters.

I intend to change my IMAP cluster for an architecture like this: Ubuntu + Ceph RBD + CephFS

Is CephFS already stable to provide simultaneous access to data in a production environment ?

Thanks !
