Hi guys, With RBD images, the theory makes possible to mount them multiple times on different servers, of course **no one** wants that. If you care about the consistency of your data :D I was wondering if ceph has any lock ability on the RBD device like DRBD does with secondary resource. Apparently not, I was able to mount an image on multiple server and wrote data on both. Is this an incoming feature? I don't really know the difficulty level that this kind of feature implies, but it would be nice to have it.
