Hi, I have been trying to figure out the actual error for bug #18576 [0] using a vstart environment, but have been unsuccessful in generating a proper backtrace for the issue. I have enabled debugging in the build using "-DCMAKE_C_FLAGS="-O0 -g3 -gdwarf-4" -DCMAKE_BUILD_TYPE=Debug". Thanks to Nathan Cutler who identified and linked the bug to #18696 [1] which shows a proper backtrace and might be the reason for the segfault experienced in the initial bug. I have enabled all possible debug messages in ceph.conf [global] debug rados = 25 debug client = 25 debug finisher = 25 debug rbd = 25 Are there other settings I am missing which will help me generate a proper gdb trace for this issue? Appreciate all the help. --Ganesh [0] http://tracker.ceph.com/issues/18576 [1] http://tracker.ceph.com/issues/18696 -- 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
