OK, I misunderstood the line causing the error. So take the advice I gave in my previous response and apply it to the command "/o pt/ceph/ceph/build/bin/ceph -c /opt/ceph/ceph/build/ceph.conf config assimilate-conf -i config.conf" You may need to prefix it with the python binary path BTW.

Hi, I am try to debug ceph-nautilus source code in CentOS7.6， and just built succesfully, but failed to run vstart.h. the log is below. Could someone give me advice?

Run this command successfully. Error in line: echo Populating config ... cat <<EOF | /$CEPH_BIN/ceph -c $conf_fn config assimilate-conf -i - I save config in a file "config.conf", and run: /opt/ceph/ceph/build/bin/ceph -c /opt/ceph/ceph/build/ceph.conf config assimilate-conf -i config.conf The callltrace is the same to before. And debug it. the error happens: try: if childargs and childargs[0] == 'ping' and not parsed_args.help: return ping_monitor(cluster_handle, childargs[1], timeout) result = run_in_thread(cluster_handle.connect, timeout=timeout) // error if type(result) is tuple and result[0] == -errno.EINTR: print('Cluster connection interrupted or timed out', file=sys.stderr) return 1 except KeyboardInterrupt:
BTW: In my case , python's version is 2.7.5.
If so you could gather a better stack trace from gdb and also valgrind output as follows.
# gdb --args /opt/ceph/ceph/build/bin/ceph-mon -i c -c /opt/ceph/ceph/build/ceph.conf (gdb) run wait for it to crash (gdb) thread apply all bt (gdb) x/i $pc (gdb) info reg
Alternatively you can gather the same information from a coredump.
# gdb /opt/ceph/ceph/build/bin/ceph-mon core.1234 (gdb) thread apply all bt (gdb) x/i $pc (gdb) info reg
# valgrind --trace-children=yes --show-reachable=yes --track-origins=yes --read-var-info=yes --tool=memcheck --leak-check=full --num-callers=50 -v --log-file=leaky.log /opt/ceph/ceph/build/bin/ceph-mon -i c -c /opt/ceph/ceph/build/ceph.conf
Gather the file leaky.log file.
The above information should be enough to begin an analysis.
