One question from one of my customers : why am I the only one to complain about that problem ? I know that Ceph users often use qemu/librbd instead of kernel client, but what is the trigger of those «race condition» ? Having "multiple requests" per RBD image ? It should be a normal use, no ? If someone can help me give an explanation, thanks :) Olivier -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
