Hi, > I hava a ubuntu 12.10 host with image mapped with rbd module. The > problem is that when this host > face a power failure all data on the mapped image is lost. If I unmap > the image via the rbd unmap command, the data is preserved. I've > noticed this problem also in version 0.56 Make sure you use a recent kernel (like latest 3.6.x or more recent). I remember having RBD corruption and panics when I was using 3.2 series, but since I moved to recent RBD code, it never happenned again.
