Sage, can you please create and foster a compatibility matrix between Ceph Kernel-components and the Ceph Userland-components ? Also the naming of restrictions and/or additional features for specific combinations would be very much appreciated. e.g. Ceph Kernel 3.0 | 3.1 | ... | 3.7 | 3.8 | 3.9 | Ceph 0.48.x ? | (1) | ... | ? | ? | ? | Ceph 0.56.x ? | ? | ... | ? | ? | ? | 0.57-0.60 ? | ? | ... | ? | ? | ? | Ceph 0.61.x ? | ? | ... | ? | (2) | ? | 0.62-0.66 ? | ? | ... | ? | ? | ? | Ceph 0.67.x ? | ? | ... | ? | ? | ? | just examples ... (1) no support of ceph.ko (2) support OSD format-2 Thanks, -Dieter -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
