Use Ceph as redundant storage for failover FTP service?

I need to setup a redundant FTP storage service that can survive one server-crash.

I have two servers SrvA and SrvB that shares a virtual IP IpVirt (an IP that will usually point to SrvA but that will point to SrvB if SrvA were to have a problem).Both servers (Debian) will have a FTP daemon and FTP users configured.

At this point the FTP daemon can always be reached using IpVirt: failover FTP service = OK

For the actual storage part I see the following options:

• rsync the FTP data directory between SrvA and SrvB
• Use a replicated file system whose nodes are SrvA and SrvB: The replicated FS infrastructure would do the synchronization job for me.

I am considering the second option: and I wonder if Ceph (which I would like to try) could do the job?

Can I make SrvA and SrvB the two nodes of a Ceph infrastructure where datas are stored on both SrvA and SrvB.But also make that Ceph infrastructure still be accessible by any Ceph client (SrvA, SrvB or any other) when at least one of SrvA or SrvB is up? A Ceph "master" failover system (client would be using that same IpVirt IP).

In this scenario, the FTP data directory would be a mountpoint for a Ceph "volume".

Note: I plan to use theses two servers for other storage oriented services (SMB, WebDAV, storage-oriented web applications...). Theses services'data directory would then be other mountpoints to other Ceph "volumes".
